View Full Version : Water Effects vs performance

12-29-2007, 10:34 AM
Hi Gents,

I have a question about tweaking my sim to get the best of both worlds. I have an nVidia GeForce 8800 GTS video card and I changed the settings in the sim to Open GL and the Attempt Stencil Buffer is lit (whatever that does http://forums.ubi.com/groupee_common/emoticons/icon_confused.gif). In my conf. file I have the following settings:



Here is the visual effects I see for water and terrain:



Here are my questions:

1. is this the best I should expect to see visually?
2. is it possible to do anything further to try and get better frame rates while still enjoying the visual effcts shown here?

Thanx http://forums.ubi.com/images/smilies/25.gif

That's... pretty good... I'd be happy with it if I were you.

Yes, I copied and pasted it directly from the file. Btw, when I select Open GL, it seems to change those settings in the cfg file automatically (I had water set to a higher setting with Direct X selected but I couldn't get the depth to appear as it does in these pictures).

I'm just trying to see if I've got things set up as best they can be. My frame rates are good, although they were superb before. Thanks for the advice. http://forums.ubi.com/images/smilies/16x16_smiley-wink.gif

hey im new to the game and i wonder why you guys use the "old" opengl over directx? was it better at that time?

IL2 is an OpenGL based game.

Try water=2. My 7950GT actually will actually render the images a bit faster and smoother with water=2. With the 8800 GTS, you should also try water=3 and 4. My 7950GT will do 3 and 4, but the frame rate hit is too much for my tastes.

12-30-2007, 02:37 PM
On my Nvidia 6800 when it was working I found that water 4 was too much of a frame hit so I used water 3.. or 1.. but never 2... You might have differing results.. I always thought that 1 looked better than 2 for some reason.

Okay, here's kind of a dumb question...but do I modify both sets of parameters where water is listed? Or only one? And if only one, which one?

12-30-2007, 06:04 PM
You mean the open GL & DX settings? I would only do one.. the open GL one.. and run the sim in open GL.

Run under openGL.
Select a 32 bit colour mode,
Stencil buffer on.
Change water= in conf.ini under the [Render_OpenGL] section.

For ATI cards water can be 0-2
For nVidea cards water can be 0-4

In both cases higher is more quality and lower FPS
experiment to find what suits you best.
Don't forget to test under poor weather conditions also.

I have an 8800GT 512 and can run any combination of settings. Personally, I like water 1. To me it looks more real, doesn't have that purplish haze. I think a lot of this is personal taste!

By the way guys,

Is the Intel GMA 3000 videocard a good one? And wich water setting could I use?

01-02-2008, 03:30 PM
The Intel GMA 3000 is a fine card for business applications but not for gaming. It supports Pixel Shader 2.0 which is pretty good but it doesn't have much power to back up the feature so it really can't make use of it. I think you *could* try the Perfect mode landscape...but it'll be a slideshow.

Ok, thanx IceFire!

But, what's a slideshow? http://forums.ubi.com/groupee_common/emoticons/icon_confused.gif

One image ('slide') visibly followed by the next one.

So you can see that the 'action' has been created by seperate images/frames shown one after the other.

In smooth play, you cannot see the change of images/frames.

Tip: Use Google Images and look for 'slideshow' http://forums.ubi.com/images/smilies/16x16_smiley-happy.gif

Sorry...thats a colloquial term. It means really really slow. A slideshow would be one image at a time, traditionally done using an old camera and a slide projector.

Translated into this context it means that it would be extremely slow and the updates between frames would be so slow that you'd be watching the updates happen. Not something you want...3D games like this need to be fast and fluid. The opposite of a slideshow http://forums.ubi.com/groupee_common/emoticons/icon_smile.gif

Well, I'm getting a new comp though, with a nVidia 8600GT. Will it work on that one or will it be the notorious "slideshow"? http://forums.ubi.com/groupee_common/emoticons/icon_wink.gif
