A note on GGPO and Windows 7’s lag.

(Crossposted from SRK)
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 also improved, but for some reason Windows Classic felt like it had a bit less 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 could likely be an illusion.

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 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 to some faster-paced FBA games.

Also, on a super-random note, if you’re recording something with with Hypercam, you probably want to set the color to 16-bit. You will get fewer video errors (video rapidly speeds up after a minute or two, etc).

Also, HIRO’s YouTube channel has updated with a bunch of videos for various games (Melty Blood AACC, GGXX, Chaos Breaker, SF4 etc).
