Witcher 2 CPU Intensive?

post #1 of 11
Thread Starter 
i keep dropping into the higher 40's during some fights and some scenes/parts of the game.
Which settings are the ones that eat all the CPU power? The game only uses 2 of my cores and this is why it is limited.
Thank you.

Try lowering AA and probably turning off ubersampling, for me it was the real performance killer, although do notice that my cpu and gpu are quite inferior to yours so i can't exactly say whether this will work in teh same way for your rig as it did for mine !

Hello mate.
Uber is turned off.
I don't think removing AA will help much seen as it is processed by the GPU, right?

I am not an expert on this but i think cpu is also responsible for AA, not the post processed ones like SMAA or FXAA.

Ok now taking Witcher 2 out of the question, here are a few things which depend traditionally on CPU to be processed

1) Shadows
2) Geometry Detail/Terrain Detail
3) Physics
4) Water processing(Unless using GPU accelerated approach)
5) Object Detail/No of entities onscreen.

Sorry if you already knew all this, but that's what i know generally speaking !

Well if anyone with AMD knows how to force AA through the nvidia CP, do let me know. Only kidding, I get what you mean.
Any tips for mouse lag? The amount of mouse lag seems to change. One minute it is very responsive and the next it feels delayed.
I can't game withoyt vsync though because I can't stand the tearing and I am already using triple buffer and an fps limiter.
Cheers!
