One of my friends, not myself, has 8 GB of RAM, an AMD 4100 Quad Core (I think it's 2.6 GHZ, I may be wrong), and a 1GB GTX 550 TI. For some reason, he can't run many games. For instance, Need For Speed Hot Pursuit requires at least : AMD Athlon X2 64 2.4GHZ, and a GPU with 256 mb and Shader Model 3.0 or higher; for some reason, he can barely run it on low settings. Why is this? There is a video of someone playing BF3 perfectly with that exact CPU and GPU. Link: http://www.youtube.com/watch?v=aW2xmZAN3uI I would appreciate any replies, thanks. PS: He has scanned for malware and such.
