ok people for the last freakin time:
1: the SP demo has no texture compression
2: it is a part of a number of lvls and has precahching problems whichs cauese the lag u see   

 its not your system, well it may but i dont think it is..plus the R 8500 is not that great..gf 3 ti 500 has better FPS count   
 
and alos try on lowering your choices for all the crap in the Multi demo  

 that should hook u up
