Phenom II x4 965 OCed to 4Ghz. My 7970 is also overclocked to 1125Mhz, memory clock to 1575Mhz. Stuttering goes away entirely when I drop the texture quality.
Yeah...maybe you are right on that texture issue with 3GB then. Its just that i keep reading conflicting reports where these 7970 3g's get maxed just like 4gb cards do? I think it was over at guru3d forums where i read this at. Maybe the game uses up all available vram for caching like some games do. I just dont know.
Like i said in my previous post which i did edit in case you didnt see it...my vram gets close to 3gb right on the 3gb spot actually at times.
Your CPU..im not too sure on that CPU being enough but than again i dont know how CPU dependant this game is...i know on my 3770k which is a quad with 8 threads which are used as independent "cores" seems to help over those without it....
I need to look into it further but thanks for your input..
