Doom 3 Mouse Lag

Tom|Nbk · 19 Jul 2007 at 01:16

Ok playing through Doom 3 on with the spec in my sig

Ultra settings
16xCFAA
16xAF

In some parts of the levels I get an odd mouse lag yet the fps seems to stay on a dead 60fps, the FPS has only dipped to around 40fps a few times otherwise. It almost feels like mouse smoothing but I have that disabled from the menu. Can anyone shed some light onto this. Loving the game so far, can't believe I didn't play it sooner

Is it V-Sync?

I get terrible terrible mouse lag with basically any game when I have it turned on.

Nope V-Sync is disabled

Running @ 1680x1050.

Since you have v-sync disabled I'm not sure it matters, but have you turned off triple buffering?

Might be worth checking your refresh rate as sometimes running framerate and refresh rate out of sync can make things feel laggy. I don't mean you should be running vsync (quite the contrary), just that with D3 limited to 60fps you might like to try a refresh rate of 60hz.

try upping your refresh rate, having a crt handy to test would be helpful, a few people complain of this and seems running 85hz+ cures it.

I know its already been said but it really really sounds like a v_sync issue. Even if its off in windows are you sure theres not a setting in the game for it thats enabling it? you might be able to trick it by setting maxfps @ 45fps..and if your fps then drops to dead on 30 (half of 60) ..v_sync is secretly on
