@ratchet: I had several problems with wrong materials and crashes until i upgraded directX, thats why i mentioned it. Also for some reason the Pacific demo has anti-aliasing ( i think thats what it is, forget now ) hard coded to full in script and always reverts to it on restart. Kills framerates on any older cards. I pointed this out to a GG employee but not sure if it will get fixed. I started using Ureal3 and loved it. The editor ran smooth on my old card, ati 5770, until about 3 updates ago. The editor became slow and unuseable with post effects on. Tried several things to get it working as before but could not. My laptop had the same issues ( nvidia 360M ) so it's not just an ATI issue. The response i got from unreal team was to just edit with lower settings.
