V-sync off?

Yuck!

I play with it on... with triple buffering on, naturally. It doesn't adversely impact on framerates on my machine (Pentium D 3GHz, 9750GT).

I think you mean 7950GT. And yes, on some systems vsync does not impact performance. But on almost all ATI systems it does, and even a few nvidia setups. It's not usually just the framerate that suffers (because it has to be a divisor of the vertical refresh rate, usually 60hz on LCD screens) but also nasty laggy stutters similar to the ones you see online from time to time. These are almost always cured by turning off vsync. I can finally run vsync on with my new system, x2-4600+, 4gb DDR800, 2x9600GT SLI.

No problems with these cards and vsync in il2, they're FANTASTIC il2 cards in fact. Absolutely beautiful visuals especially with 16xSLI AA.
