There is a fix to make the game playable on geforce 7 cards even without the patch which would be out soon…

It runs much better than G3 on a low end machine BTW

I tried on a test machine with geforce 7800 , 2 gb ram, and an old AMD 2.2 ghz processor… plays quite ok, even in combat…. G3 would be completely unplayable on this setup in comparasion even after a lot of modding…
