Stutter and Mouse-lag - even on lowest settings!
I already posted this in a topic from someone else, but I figured that people might overlook my question there and I really would like an answer to this problem, so:
I run The Witcher 2 on an iMac 27inch from 2010. I run Windows 7 (64bit) through Apple's Bootcamp and most games run smoothly on my iMac. However, The Witcher 2 runs terrible even with the settings on Low and the resolution turned down.
The problem is that the game is "stuttering" and the FPS keeps changing between 30FPS and 10FPS at a frequent pattern (every 2 seconds or so I have a huge framedrop resulting in the game sort-of freezing for a brief moment. My mouse also lags terrible and the mouse is terribly slow even if I turn up my sensitivity.
I have tried turning-off the vsync, but no luck there. I have tried turning off all effects, including SSAO, Bloom, Motion Blur and Blur Effects and Uber-Sampling. Still, no luck.
My specs:
model: iMac 27' (2010 build)
CPU: Intel Core i7 "Lynnfield" (2,93Ghz)
GPU: ATI Radeon HD 5750 (1GB)
RAM: 1333Mhz DDR3 (8GB)
The Witcher 2 launcher specs my iMac at "Medium Spec", yet even at "Low Spec" the game still runs awful, with lots of stutter and an awful response time.
Why does my machine not run The Witcher 2 properly? I did (clean) install all the latest drivers for my GPU and I also (clean) installed the latest DX10 and DX11 drivers!
