The Devs have said that current graphical issues should no longer be an . . . issue as the Graphics Engine re-write will be from the ground up, so other than looking the same, it should not have the same problems this has. They've also said that they are working with both AMD/ATI and Nvidia, so one card shouldn't really have an edge over the other with regards to graphical issues.

Sit tight and hopefully the new graphics engine and patch will be out in another two weeks.
