I'm currently trying to run The Witcher: Enhanced Edition (the 1st one).
My specs are
Windows 7 Ultimate
Core 2 Duo 2.66GHz
4GB of ram
Geforce GTX 550 ti
GPU driver up to date. Game patched to 1.5 which I believe is the lastest version.
I have no idea why the game is running so poorly. It stutters everywhere, both cutscenes and in game. I tried running it at the lowest resolution 800 x 600 and the stutter does get better but doesn't go away.
The machine runs Need For Speed the run fine, it runs Battlefield 3 fine on medium settings. I have no idea why it's not running a 5 year old game on lowest settings.
