Slight improvement in Performance, but buggy.
If you tab out of fullscreen back to desktop and then back to fullscreen again, theres a big chance of bloom effects and weapons textures going all screwy.
Running a GTX 480 here. The performance is a tad better, but everytime I alt-tab to the desktop and head back, the screen is completely colored with a single color (usually blue or yellow) for one or two seconds. Nothing to worry about, just a bit annoying.
The game still stutters extremely bad on Starbase 1, I simply don't know why sometimes it is really difficult to move or look around there. I hope this gets fixed sometime in the near future.
Im glad someone started this thread. I was wondering if all the people that are having hard crashes to desktop with their NVIDIA cards would report any improvements after download this latest driver here. Im having those troubles myself and just downloaded it late last night. I have yet to test it.
