I put this in the General Hardware section because it could apply to both Nvidia and ATi GPU owners, and there is no section for "Videocards - General" or whatever. I guess you can move it to somewhere else if you think it doesn't belong here. I thought about putting it in the "Games" section, but it's not really specific to one game or type of game, so I'm not sure. Anyway.... Do any of you use VSync without the side effect of some mouse lag? I'm really disappointed about this. My games tear like mad with VSync disabled. It does not matter if I lock the fps at 60 either (UT3 is locked around 60 fps for example). If Vsync is off, it tears bad. No matter what Forceware version I have used. I have a Logitech MX510 mouse. I have tried many things to fix this problem including the following: - Force Triple Buffering (did nothing) - Change Vsync pre-render limit to "1" (seemed to improve barely a little bit at first, but I think I was just imagining) - Turn Mouse Smoothing off in game (this actually makes it worse) - Install Logitech mouseware (made it worse also) - Tried everything in both XP and Vista (nothing worked) - Tried different video drivers (same results) There are two things left that I haven't tried yet: - Hook the mouse up via PS/2 instead of USB. I lost the USB to PS/2 adapter I had before, but I have acquired one here at work that I'm going to try tonight. - Buy a new mouse. Right now I'm just putting up with the tearing. Even though it looks bad and is quite distracting, I'm still more accurate with my aim because the mouse doesn't lag. If anybody has any ideas they think might work to fix this, I'm open to them. I think I've pretty well covered everything though, aside from the last two options I mentioned. My question to those of you who don't get any mouse lag with VSync, what mouse are you using?
