Mouse lag, Windows 7, FPS Games

|cJ| · 1 Mar 2010 at 16:27

Just installed some new hardware with windows 7 64bit, everything seems good but..

Have been looking for ages but can't find any answer.. My mouse is fine on desktop but in FPS games it is a tiny bit laggy? I can't find any soloution and it's annoying! Have tried messing with video settings and mouse settings but still laggy in game. My pc can cope fine with the games so I don't really know..?

Ignore Sig spec it's now wrong..

Try disabling Windows Aero and see if it still happens.
Are you playing with VSYNC on?

Tried turning off vsync?

It's probably vsync, turning vsync off in game or in your control panel wont help either as windows forces vsync with Aero. It should disable vsync if you are running in full screen, so I assume you are running in window or borderless window mode? Right click the games .exe, click compatibility and disable Visual Themes.

Thanks guys, I thought I'd tried vsync as I turned it off in the game options and set NVIDIA setting to 'let app decide'. Made no difference. I had to force disable in NVIDIA settings even though I told the game to not use it it was still doing it.. thanks

I'm assuming you have an LCD? Then leave vsync on and change the maxfps to 59.9.. Each game is different on how to do that.. But as an example any mouse lag i had in COD4 and WaW is completely gone after changing the maxfps to 59 or 59.9

What mouse are you using? Have you tried disabling OS acceleration?

|cJ| · 2 Mar 2010 at 10:55

Yes I do have an LCD. Is there a way to change maxfps to default to 59.9 in all games?

I noticed some mouse lag in BFBC2 on Windows 7 on an LCD, and it was gone once I ENABLED Vsync.

nope, each game find out how to activate the console and google the command needed.

Call of duty series its seta com_maxfps 59.9

another game it may be maxfps 59.9

Personally I'd just make sure vsync is disabled all the time unless you find you can't put up with the tearing. It's inherently better in terms of input lag.

What lag? Do you have lag when you are using windows? As lyon said Aero forces sync on when on your desktop. You can't tell me you have mouse lag there?

Half the time input lag is just blamed on vsync when it's probably a bad mous driver or someone using a wireless keyboard.

Mouse lag on the desktop is hardly going to be noticeable compared to something like a FPS game where the screen is rotating around! Plus it's not something that really matters, an extra frame of latency is irrelevant for desktop work, not so much for fast paced gaming.

There can be other causes of input lag but vsync is definitely one of the culprits. In Quakeworld, there's even a way to measure it ( http://www.quakeworld.nu/forum/viewtopic.php?id=2444&p=1 )

As for wireless keyboards, I've never had one, and I use ezquake's raw input mode (unbuffered) for mousing,
