Prior to/after patch 1.1 and 11.5b hotfix I was experiencing stutter.
Here is what I did (TW2 1.1):
1. Reverted back to 11.5a hotfix (I have a single GPU so I assumed 11.5b wouldnt do much for me)
2. Used Defraggler to defragment ALL witcher 2 files
3. Replaced Fraps with Dxtory (a different FPS measuring tool)
I suspect that Fraps was the main culprit. When I switched between Dxtory and Fraps, Fraps always had the microstutter. That being said my loading times have improved since I defragmented the witcher 2 folder.
My system specs:
i5 760 oc to 3.8
4gig ddr3 1600 gskill ram
1 TB 7200 rpm HD
Sapphire 4830 512mb video card (I know I've been contemplating upgrading)
I get around 30-40 FPS in folstam on 1920x1080 with all settings set to low specs. I want to run a lower res with improved graphic options but the black bars annoy me.
Let me know if this also works for you guys!!!!
Edit: Attached pics of CCC overclock and Witcher 2 config in case anyone wanted to see.
