Framerate drops when changing weapons and zooming in and choppy mouse movement

[Storm934 0]

I'm having a problem where when I change weapons or zoom in with the sniper rifle the framerate will drop. I tried using this patch but it didn't work.

I also tried using dgvoodoo which helped a little but the framerate still drops. The other problem i'm having is choppy mouse movement even with the patch above. Any solution would be greatly appreciated.

Have you tried running the game in windowed mode?
