I assume you guys would be aware of this- after I looked into it, it seems to be a fairly well-known issue. But since I’ve already posted it in 3 different places, I figured I may as well post it here, too.

I mentioned in the last thread that there was some input lag while using Windows 7.
After doing some moderate investigoogling, this seems to be an issue with vsync, which Win7 uses for everything in the standard Aero layout (the one where with all of the pretty semitransparent borders). This can be addressed a number of ways, the simplest being to go into the display settings and change your layout to Windows 7 Basic, or another non-Aero layout. I tried High Contrast Black and things were also improved, but for some reason Windows Classic felt like it had a bit more lag than either of those two.
I also tried changing the color from 32-bit to 16-bit (under monitor settings), and there seemed to be another improvement. However, it was less noticeable than just switching to a non-Aero layout, so it may just have been a coincidence.
In my case because I’m using a windowed application (GGPO/FBA) I went into Win7′s graphical properties menus. But if you’re running a fullscreen application of whatever game you’re playing, you can just go into the game’s options menu and turn off vsync. I tried it with the PC version of SSF4:AE, and the difference was very noticeable.
When you turn off vsync the game will be slightly less pretty, but it wasn’t a big deal in SSF4:AE, when compared even to some faster-paced FBA games.
