There is also a bug where if you have an nVidia card, your game can crash randomly. Lucky for me though, I have my awesome Radeon 8870
That's why they run betas... update to the most recent drivers will solve those kinds of problems. They released new drivers yesterday I think for nVidia cards to improve performance and bug issues.
nVidia is teamed up with BF3 ...
GeForce system requirements check. That used to (maybe still does, idk I use nvidia) that your computer was not ready if you were using AMD/ATI cards,
.
I heard the opposite, AMD cards were having issues with the beta, but of course, they had fixed it.
