There is no problems while shooting Rei, weapon system is really fast and optimized enough, I see no problems with it. I get problems with simple trees and grass even without shooting... For trees collusion, I placed invisible box with polygon flag, tree itself is passable. My system is: Windows XP, AMD Athlon 64 3200+ 2.21 GHz, 2.00 GB Ram, NVIDIA GeForce 7600 GS. About 59-60 jecrking fps, Quad you really think that's ok? I see that in my other projects as well... They are way more simpler than the one I've described in first post. As well, what is good fps to play in your opinion?
