View Full Version : What's the verdict? V-sync on or off?

In D3d and OGL. What's better and what's the trade off (FPS vs. Grafix wise)?

For me it's off, I use excellent setting at 1280 by 960, plus x4 aa and x4 ansio. So I like having the slight frame rate improvement since most the time I'm looking forward. For me there is tearing when I pan around, but it's not a big deal.

WOW, so far 50/50 split for/against V-sync.

Hmmm, still wondering whats best????? http://ubbxforums.ubi.com/infopop/emoticons/icon_confused.gif

If you use TIR, definitely on. With it off, things 'break up' when you pan around.

It's this type of statement that always confuses me. I see no improvement in framerates at all.
For me, having vsync off allows my framerate to rise up past the monitor freqency (85hz). If I have vsync on, the maximum fps is 85 (when I look at the sky on an empty map). If I have vsync off it goes up to 95-100fps looking at the sky.

But my average in-game fps is much lower than that (25-60), so vsync makes no difference at all to that average framerate. So it seems that vsync is only relevant if your monitor is stopping your video card from performing to it's maximum.
But even if your card could push the framerate past 85fps, why would you want it to?? I can't see any difference in the quality between 60fps and 85fps?

Under OpenGL is it necessary to also enable triple buffering with Vsynch on?
I recall seeing it recommended somewhere (Coastie perhaps?).

Basically you may be confused because your framerate is way higher than mine. Because of my settings, my framerate will almost never reach the full refresh amount. My framerate on average is about 28, or as low 13 as low over cities, etc.. From doing the blackdeath track vsync on took about 3 fps from my average. So the difference is really between 25 and 28 roughly. Hope this helps...

On, tearing is distracting for me. If I disable Vsync, I can clearly see tearing at framerates of only 20, just 1/3 of my LCD's native 60Hz refresh rate. This happens most clearly while panning in FB, FS2004, and LOMAC. I had assumed that tearing was only problem when the framerate exceeded sync, but aparently not?

BTW, I was asking in the LOMAC forums earlier, does LOMAC ignore the vsync setting in your video driver? With my nVidia panel set to enable vsync, tearing is gone from all games except LOMAC, and my framerates in LOMAC will easily soar above sync in external views. Anybody here have any ideas on this?

On due to TIR2 (got bad tearing on cockpit side structures otherwise). Incidentally, didn't notice a performance hit when I turned it on but didn't test it properly.

OFF for me, better performance, no side effects, but I am not using TIR or anything like that(never heard off it).

What is TIR anyway???

On here - have tried it off & got 15-20 fps but bad tearing when panning. One thing: my monitor is 85Hz but my fps is either 30 (in-cockpit) or 60 (external) no matter what - never in between! How come it's not 85?

Ok, daft question, how do you turn vsync on/off - is there a desktop option for it or can you do it in FB? I have rather cr@ppy intel onboard gfx so any improvement in fps, however slight is welcome http://ubbxforums.ubi.com/images/smiley/16x16_smiley-very-happy.gif

TIR2 user therefore ON

@ASM: go to graphic settings for D3D/OGL and there is a V Sync slider [allways off - default off - default on - always on]
(at least on ATI control panel).

Right-click on the desktop, click on properties/settings/advanced - should bring you to the Display properties for your gfx setup. Hopefully you will have an option to adjust these prop*s for OpenGL - look for a slider marked "wait for vertical sync" and set it to "always on". That's how it is for an Ati card....dunno about any others, but they should be similar.

Oh, and it's ON for me as a TIR user too

I've noticed this too and assumed that it has something to do with DirectX, but LOMAC definitely seems to ignore the vsync button.

Off and I use TIR and TIR works just fine. I see no advatage to having TIR and V-Synch on.

The FPS hit with V-Synch on is just too much for my medium-level CPU.

Whats TIR?

@ solidog!

This is TIR! (http://www.naturalpoint.com/trackir/)

Basicly its a "camera" that can see your headmovement and use that as a mouse movent to pan arund.

Andrew try looking in your bios -some have options for disabling v-sync

BTW - off for me

a quick definition culled from the web for those interested.

Video Synchronization (VSync) is the synchronization of your graphics card and monitors' abilities to redraw the screen a number of times each second. This is measured in Hz (which is the same as frames per second), and your monitor will have a maximum rating in Hz for each resolution €" e.g 1280x1024 at 85Hz. When off, your FPS will improve slightly, however, you may see some image "tearing" as your monitor and graphics card go slightly out of synchronization when the refresh rate exceeds the monitor's abilities. Turn off VSync for best graphics performance, however if the image tearing is annoying then turn it on
