I'm using a BFG 6800Gt 256mb card on open Gl settings in Perfect mode. My typical FPS was in the mid 30s in the cockpit and no more than 75fps when looking skyward.

So I tried a tip I found on the net. I turned off the Vsync and increased my refresh rate to 85hz and saw MAJOR improvement in my frame rates. Skyward is 130-140 fps and 50-60 in the **** pit.

"It seem the refresh rate set in you monitor effects your FPS. Normally the default is 60hz.
VSync enabled actually means that the graphics card must wait until the monitor reports back that it has completed its redraw operation before it will send it's next command to draw the next screen. Thus, they are always in sync.

VSync off allows the monitor and vid card to move as fast as they can without as much regard to what the other is doing. Most of the time with a modern system, this is fine. Sometimes, however, you can get visual "tearing" of the screen. You would know it if you saw it.

With VSync on, your FPS will be limited to your refresh rate. With it off, your card will draw as fast as it can. This may or may not increase your FPS."

Again with the Vsync OFF and increased refresh rate to 85hz ....My fps went up substantially.
You can find the Vsync under Performance and qualitity settings for your card.

Yes it will boost FPS,but if you fly with cockpit on then you get nasty tearing of images.The frame of the canopy tears and looks horrible.Since I always fly with cockpit on , v-sync is a must.Besides,30 FPS on perfect settings ain't that bad. http://forums.ubi.com/images/smilies/16x16_smiley-wink.gif

My refresh rate is 120hz, so leaving V-sync on is not a problem. I don't like the tearing in the cockpit with it off.

Rgr I can see tearing of the cockpit around the window frames a little but I'm using Track IR so it really isn't that bad for me.

Actually is when using a track ir that Vsync is important . run smooth with it ON

Maybe a stupid question, but is this Vsynch ON also important for LCD monitors ?

I set the Vsync to application controled and it works well with TrackIR.
