Just want to know if anyone else experienced stuttering issues after the patch? I saw some very noticeable stuttering in outdoor / grassy areas after applying it. With the same exact game and CCC settings, I was playing with ZERO graphical issues before 1.1. Incidentally I tried a modified exe w/o the DRM before the official patch and I saw this same exact problem, that's why I reverted back to the original executable.

Any ideas on how to fix this?

Specs:
6950 HD, i5 2500, Vista 32bit, 4 GB Ram.
New file version: 1.1.6157.43917

Yep, there's a number of us suffering from it in this thread. There's a few possible solutions there, though none of them completely get rid of it for me.

Before 1.1 it was fine in my retail copy.

I see, thanks for the info. Looks like I'll put this game on hold for a while until this gets sorted out.

Yep same here
