View Full Version : IL-2 Setup Explained

I've seen confusion and misunderstanding of some of the settings in IL-2 Setup so I thought I'd explain what each setting does. I know you all probably understand most of the settings but there are a few mysterious ones that you may have wondered about. Also, most of my reccomendations are for better performance on low to mid range computers.

Driver Tab
Providor: OpenGL or DirextX. OpenGL will most often give the best performance, especially on Nvidia cards, but try both and see which one gives better performance.

"Full Screen" mode is the standard way to play the game and will often give the best performance/stability.

Video Mode: Choosing lower resolutions and color modes will greatly increase framerate and lower memory usage. 32-bit color is needed to enable "Perfect" mode graphics. For a low range PC, I reccomend 800x600 with 16-bit color.

"Use Stencil Buffer" enables translucent shadows (instead of full black shadows) and is required to enable "Perfect" mode graphics. For a slight performance boost, turn this setting off.

Video Tab
Texture Mipmap Filter: Simply put, this setting affects how sharp a texture may look when viewed from large angles or distances. Anisotropic offers the best image quality at a usually heavy performance loss (only folks with good video cards should use this), and bilinear filtering offers the best performance at a still acceptable texture quality. Trilinear is a tiny bit better than bilinear (it smoothes the transitions between mipmap levels) and the performance hit is very minimal depending on your video card. I reccomend bilinear but it is up to personal taste and your hardware.

Texture Compression: This setting can greatly reduce the memory load and increase framerate by compressing textures. S3TC gives the highest compression ratio and may cause some minor artifacts like little squares on water but it can greatly help or eliminate stuttering (16bit has a smaller compression ratio and less performance boost but also a bit less artifacts). I reccomend S3TC compression.

"Use Dither" helps eliminate the ugly color "banding" when running the game in 16-bit color mode. Has no effect in 32-bit color mode. Reccomended on in 16-bit color mode and can be turned off if running with 32-bit color.

"Use Vertex Arrays" gives faster performance without image quality loss because it allows vertices to be used in groups (arrays) instead of individually. Turn this on.

"Polygon Stipple" is a way of emulating or faking translucent shadows when the stencil buffer is turned off. It does this by creating a "dotted" effect that looks translucent (not unlike the stubble of incoming facial hair). Turn this off for a small performance boost. If stencil buffer and polygon stipple are both turned off, you'll get completely black shadows which isn't much of a drawback.

"Multitexture" affects all multitexturing used in the game, most notably, some water effects, and the very high clouds that are textured to appear more "chunky." Without multitexture, these clouds are smooth white instead of textured. Highly reccomended to leave this on but turning off yeilds performance boost.

"Combine" allows more advanced multitexturing effects. For example, the murky water effect near edges of rivers to simulate shallow depth uses this extension. Turning off gives small performance boost but I reccomend to leave it on.

Turning off "Secondary Color" creates graphic anomalies during fog. For example, nearby forests may not appear to be "fogged out" while everythng else is. This may give a performance boost when turned off but I reccomend it to be left on.

"Vertex Array Extension" allows the use of vertex arrays as explained above. Reccomended on.

"Clip Hint" tells the driver that clip volume clipping for primitives is not neccesary. Basically, it tells the driver not to worry about something the game doesn't do anyway. Minor performance increase when checked (about 1 fps). Reccomended on.

"Use Palette" uses paletted textures instead of full color textures. This can save memory with little to no image quality loss. About 1 fps increase when checked. Reccomended on.

"Texture Anisotropic Extension" should be checked if you selected anisotropic as your mipmap filter. Otherise, uncheck it.

"Texture Compress ARB Extension" should be checked if you're using S3TC for texture compression. Otherwise, uncheck it.

Sound Tab
Playback Channels: The number of channels sound can be played through. Fewer channels give better performance. 8, 16, and 32 are your options but 16 is pretty much the minimum or else sounds may cut out when firing the weapons on a plane with many guns. I reccomend 16 channels.

Speaker Type: Self-explanitory, select your setup.

"Reverse Stereo" should only be checked if your left/right sounds are reversed.

3D Engine Mode: Affects sound engine quality/features. Settings are self-explanitory. I reccomend the minimal mode though I notice very little quality differences between the modes.

Sampling Rate: Affects the sound quality (clarity), lower gives better performance. It's up to personal preference but I reccomend 22050 for low to mid range PC's.

"Audio Enhancements and Hardware Acceleration" enables the use of hardware for sound and uses more sound features/effects. Some people report an increase in framerate when this is turned on (Audigy 2 for example) and others report a decrease (Turtle Beach Santa Cruz, some Soundblasters). You should test which setting gives best performance on your card.

EDIT: Fixed some typos and added a bit more info. Also, since IL-2 uses Java, I highly reccomend everyone get the latest verion of the Java Runtime Environment ("JRE 5.0 Update 4"). You have to scroll down to find it, don't get the JDK or other stuff.

The only thing i would like to add is that when you own a soundcard like an Audigy 2 (no on-board soundcard), you better DO check the "Audio Enhancements and Hardware Acceleration". Your performance will increase significantly, cause it allows the use of the soundcard instead of leaving it all to the CPU.

Correct me if im wrong though..

I did some investigation and yes, hardware acceleration normally relieves some stress off the CPU in most games but in IL-2 it seems that the new sound enhancements used with hardware acceleration cancel out any gains (usually very minimal to begin with) from the hardware use and actually decreases performance. I have a Turtle Beach Santa Cruz, a relatively high-end sound card capable of hardware acceleration, and turning on Hardware acceleration turns on some sound effects but hurts my performance. If anyone else can report otherwise, I'll be sure to edit.

Although I have an older SB Live XGamer, bought around 2000, I leave H/W acceleration unchecked for the same reasons. Yes, it yields better sound effects and such with it checked, but the performance hit doesn't justify it for me.

Sound setup seems to be a major cause of stutters for me. So, applying what you've written in this thread with my own experimenting, I've found a very playable happy medium.

Thanks again for the info. It's people like you that make the internet and this community a better place for all.

When i had my old P4 1.5GHz i tried to run with and without hardware acceleration and it gave me best performance/quality rate when i checked the hardware acceleration. I can't test it anymore since my new CPU is reducing the difference between the 2 settings to 2-3 fps.

I remember the performance boost when i sticked in my soundcard for the first time. Perhaps my settings are not that efficient though.. http://forums.ubi.com/images/smilies/16x16_smiley-wink.gif

Raptor852, IMHO, is absolutely correct. If you own an Audigy 2, there is no way in heck I would ever settle for NOT checking "Audio Enhancements and Hardware Acceleration." First, it not only provides the better sound quality, but it does provide a performance increase. Simply benchmark if you have an Audigy 2, and it should become readily apparent, especially when you are using 16/32 playback channels and a high sampling rate 44100. The playback channels are offloaded to be processed by the soundcard, and not the CPU. This is why if you are NOT using hardware acceleration, this setting will have the biggest impact in sound rendering and the creation of stuttering, since it would then need to be completely processed by the already busy CPU! I really don't see how this could be recommended for Audigy 2 owners, unless I am completely missing something else, which I'd welcome to hear....Just sharing my experience.

Thanks for the input, I based the info on my and a couple others experiences. It appears this is one setting each user will have to check and benchmark for themselves as it varies with soundcards. I will make an edit.

Trilinear is a tiny step better looking than bilinear (I can't really explain how it's better, it makes the transition between mipmap levels a bit smoother but I don't know if you'll understand that). It's almost unnoticable, especially in this game. Also the framerate hit on most cards is minimal to almost nothing. However, the transition from trilinear to anisotropic is much greater, image-wise and performance-wise, only decent video cards should use anisotropic. I reccomended bilinear because I don't care much for the minor benefits of trilinear but selecting won't hurt much at all.

I found some pictures from Quake 3 showing the differences. Notice how trilinear doesn't improve the texture quality but simply smoothes out the transition between detail levels. And this is zoomed in a lot so the difference isn't that visible in normal play.

The change to trilinear has an impact on how textures are drawn especially over distance. A small test: Load the game in bilinear & fly over a road & see how the texture "ends" at a given distance. Do the same in trilinear or anisotropic & the texture "narrows in" in a more realistic way.

That's related to this game using EAX, for further info, the Cirrus Logic CS4630 does in hardware 4.0 directsound3d channels (I have an old terratec sixpack 5.1+ based on one), the center channel only plays mono sources (as rain in il2) as it's only emulated for 3d sound (altough it's another story for 5.1 in movies where it has full 6 channel support), some soundcards using this chip can do 5.1 3d, but there's emulation too. Some much newer builds with the less expensive cs4624 can do up to 7.1 full 3d whith extra hardware (double the 4.0 part for 8 channels).
Back on subject, this game uses EAX (a dsound3d extension) wich only creative cards support by hardware, altough your cs4630 can do pure hw 3d positional audio in dsound3d, to use eax extensions it will have do software emulation using a wraper to sensaura which consume a lot of cpu cycles compared to plain dsoun3d operation. I haven't done testing on it, but forcing eax 1.0 might give better performance than either letting it emulate eax 2.0 or running without hw sound acceleration.
On some games wraping eax 2.0 to sensaura gives a lot of stutter, like a ugly stutter in every 10s, I've seen this in codemasters games as CM 4, toca racedriver, xwing alliance (disabling 3d sound solves), midnight racing 2 and KOTOR. The usual recommendation to set sound acceleration to standard instead of full works on some cases because it disables extensions as eax, but from the top of my head, I don't remember if it disables hw dsound3d too (altough dsound "2d" hw mixing will remain).

Btw, don't be shy on your cs4630, good implementations of it as terratec's (can't talk about turtle beach because I never had one)had much better snr's and overall sound quality than CL's Live series at that time, and to be honest, my Audigy 2 sounds much more metallic and lifeless than my terratec for simple stereo audio playing. The audigy series simply sound awfull on 44khz because on-the-fly oversampling to their native 48khz.
Newer via Envy24 based cards even much better than creative ones on true sound quality, but again, they are even slower than old CS's for dsound3d with creative extensions which seems like a plague that renders anything non creative for 3d games. You can have a great 3d APU, but if doesn't EAX by hardware on top of dsound3d (read non creative card), it's almost useless, except for soundstorm wich does eax1.0 at least as fast as an audigy, but suffers with 2.0 and time will tell what will happen with the new 4.0 standard.

Thanks for the info! I will set my DirectSound to standard to turn off EAX and do some testing (I did some reading and setting DirectSound to standard still gives you hardware acceleration but just turns off the third-party things like EAX). My card never like EAX so that's probably the reason for the performance decrease.

And tjaika1910, the only setting that affects what the menus look like is the texture compression setting. S3TC Compression often makes them look a little ugly but trust me that game still looks just about the same and the performance boost is worth it to me. 16 bit compression makes the menu screens a little better but still not perfect and setting texture compression to None will give you normal uncompressed munu screens. And I'm not sure why you can't change your stencil buffer setting, try the in-game stencil buffer setting as well.

I can uncheck it but the stensil buffer gets reenabled every time I start the game. Ingame I can switch it off, but after pressing "apply" its there again.

I just want to make sure, you're not trying to download the "JDK 5.0 Update 2 with NetBeans 4.0 Bundle," are you?

If you are, you gotta scroll down and get the "JRE 5.0 Update 3," Not the JDK. The other stuff is mainly for developers, not end-users.

can uncheck it but the stensil buffer gets reenabled every time I start the game. Ingame I can switch it off, but after pressing "apply" its there again

If you have one of the newer ATI cards you can not disable stencil buffer.

Now on to trilinear filtering I much prefer this over bilinear for 2 reasons, first if I use bilinear it accualy cuases stutters for me, this may be linked to how ground objects suddenly spawn at close range and at a higher level of detail and second it looks just awe full imho, also the change in FPS between the 2 is just to small to matter.

In flight sims were we need to see over large distances the sudden change in texture quality is just too obvious for me. Having said that if you need to run it for performance reasons then do so, different systems will give very different results

Covino well done on the guide. I know of many people that will benefit from this.

Thanks Covino, I'll check it out. just doing a update from the Java program in "control panel"

Might be a combination of stuff (moving to custom settings, Installing Java, defraggring my HD) but I have just experianced a 4 fps average jump in perfromance. Great work, thank you very much from all the computer illiterates out there http://forums.ubi.com/images/smilies/11.gif

Thanks for the advice, but.....

How do you measure fps within IL2?

(I currently measure framerate by 'stutters with AA' or 'doesn't stutter' ... http://forums.ubi.com/groupee_common/emoticons/icon_rolleyes.gif )

Thanks!

An easy way is to enter the console (shift tab) and type "fps START SHOW" case sensitive. To stop type "fps STOP SHOW"

And you can also get FRAPS (www.fraps.com (http://www.fraps.com)). It can show your framerate in any game and also has benchmarking, logging, screenshot, and movie recording capabilities.

Thanks Covino - a great help for a newbie like me. Just purchased the game this weekend bargain bin for $10. I see I have a hell of a lot to catch up on. Haven't played a flight sim since Secret Weapons of the Luftwaffe!

Thanks Covino. I've been flying for a while and never had a clue when it came to most of the setup functions. S!

Just wanted to share. I just reformatted. I setup IL2 Setup the way I had always ran it. Actually the way I had been advised to run it, which truly, was the way I had always ran it with the exception of a couple things. Anyway running 6A AA & 8X AF in Perfect Landscape and setup after my reformat the way I always used it I had a Min=15 Max=87 Avg=39.48 Then I used Covinos recomendations with the same settings and got Min=16 Max=99 Avg=43.247 WOW!! Anyway, I am an eye candy freak so I decided to set the AF to 16X. Then I got Min=16 Max=100 Avg=42.093 Truly incredible m8's! This is with my Texture Mipmap Filter set to Ansiotropic! This is one of the best stickies I have ever had the pleasure of implementing. Super Covino! Thanks!

Ok this is probably one for Dexmeister but... a friend finally has 3 monitors for his PC. How do I get IL-2 to work across all 3?

Just to clear something up about stencil buffer.

If I recall correctly, SB is auto enabled when 32 bit color is used. If you want to disable it, you will have to switch to 16bit resolution.

id like to know your opinion about the Harware sound acceleration ...

I didnt make a benchmark to compare if i get more fps if i disable\enable it..
but i can tell that i hear "better sounds" (louder, clearer and i can distinguish the sounds of other plane's engines when they get close to my cockpit, alarm noises..ecc) when i leave it disabled ! but theorically i should get that better sounds enabling it...i can t explain this.

My audio card is the one integrate in Nforce 2 motherboards and the audio chip is a Soundstorm.

This is not uncommon at all, for any game even. I'm no expert on sound but sound features/clarity are dependant on your sound card, the game, and especially how well the game makes use of your sound card features (which is not always done so well or doesn't fit the user's tastes).
Perhaps the sound isn't as good with hardware acceleration because the game has a problem with your sound card that doesn't show up in software mode since the hardware features are bypassed, or maybe the game's more advanced hardware sound features just plain don't sound as good.

Since hardware accceleration is something that varies so much from computer to computer, both quality and performance effects, it's something each user must test for themselves.

I'd just like to add that I prefer trilinear or bilinear filtering in this gamer. I notice the difference - the scenery is clearer and transitions more smoothly into the distance. I also notice forests are rendered better this way.

I'd also like to say that I own a low to midrange computer with a 9600XT card. I play the game at medium video settings only rather than the higher quality (ie excellent or perfect) settings that most here seem to. I have my OpenGL anti-aliasing set to 4x and anisotropic set to 2x quality in the ATI control panel. Over the last couple of days I have run the game in this configuration whilst trying every OpenGL driver that will work with this card - from Catalyst 3.0 right up to 5.6. I was extremely surprised to notice that not only did the original Catalyst 3.0 OpenGL driver provide better image quality, but the FPS minimum in the Black Death track was about 4 or 5 fps better than any other subsequent driver. The average fps and maximum fps were also quite a bit higher than with subsequent drivers. Over the last few days I have continued to experiment with the 3.0 driver and so far I can't see any reason not to use it. The performance is noticably better and it seems to work fine (presumbly unless you try to play the game at highest visual quality levels - which I haven't tried since the computer would choke anyway).

Darn. It looks like the 3.0 driver on my setup was too good to be true. I was flying some missions last night and noticed that there was a lot of texture tiling in the landscape popping up. So I tried the 3.2 driver last night. So far no texture tiling, the image quality is still better than the more recent drivers and performance is a tad better. Clearly more experimentation is needed though. I would be happy with the latest drivers, but on my setup there is a clear loss of image quality with any driver from 3.6 onwards.
