The case is this. Before I reinstalled my computer a couple of weeks ago I could run The Witcher 2 on Ultra (with Ubersampling activated) with no lag. Now, after reintsalling Windows I can't run The Witcher 2 on Ultra with ubersampling. I have updated my Nvidia card to the latest beta driver (290.53), but I still canæt run The Witcher 2 without lag.

The game it self is actually not lagging, but it is the mouse sensitivity, camera control and when Im moving Geralt which is lagging. Any help?

I have done a couple of tweak guides, but nothing worked so far. Do I need to install a finished Nvidia driver and not a beta driver maybe?

Sorry for my bad English.

Update: I also forgot to say that the gamr started lagging after updating to the newest version of the game though the launcher.

Update 2: After palying a bit more, it seems it really is just the mouse, camera and movements which is laggy.

Lagging issues use to be related to low FPS.
Are you getting under 30 FPS when you get the mouse lag ?
Yes, it is under 30 FPS, but why is it under 30 FPS after 2.0 update?

I may be wrong, but I don't think this is about 2.0 update.

Did you change something else when you reinstalled Windows ?
Have you installed a different antivirus?
Are you using a bigger screen resolution?
Have you the used the same settings at your video card driver?

PS:
You may want to put this question at http://en.thewitcher.com/forum/
I used to be able to run at 1920x1200 with no lag before 2.0 a well, and now I run at 1440x900 to get about the same performance. I never did figure out why that is. But something about 2.0 definitely caused/causes a performance hit.

I notice the same thing -- I just started playing TW2 actually with my semi-upgraded rig (so I don't know what the performance was like before the update) and while it plays in High/Ultra fine, when I'm running it feels like I have high latency lag. Something I get when I play MMOs on a slow connection. It's VERY subtle.

The actual FPS is fine, especially feels great in combat -- it's just when running.
