Amnesia lagging/slow on menu/game

[kailip]

Using a 6150SE should be done with the settings you are using, it is the very low end of supported cards, so it is not capable of running with any of the higher settings.

Because Im in the process of getting a new computer (for work purposes) what type of graphic card would you recommend?

a good one... o-o
ati are cheaper, and nvidia have physx and 3d and stuff
