I'm so sorry to hear that you cannot enjoy the game
The problem is that the game needs a very very very fast gfx card. And with my patch, it needs around 30-40% more gfx power.
MSAA 4x: 7900GTX 56GB/s @ 1280x1024 -> 85 fps
MSAA 4x: 8800GTX 100GB/s @ 1280x1024 -> 130 fps
SSAA 2x: 8800GTX 100GB/s @ 1280x1024 -> 100 fps
SSAA 2x: 8800GTX 100GB/s @ 1920x1200 -> 55 fps
You'll need a 8800GTX to run 1680x1050 with MSAA 4x @ 100fps +-
About VSync, it works from nHancer, and you can say bye to tearing, and also, i could enable triple buffering directly from my patch, to help you with the framerate, but, there's another problem. If you enable Vsync, there're problems with the gameplay (you can't execute some combos, or throw people with the harpoon, ...) That's why i didn't implement it. Anyway, prolly i'll add that option to help with the triple buffering.
