And while I am asking questions, do FPS settings impact jumping?
I noticed when I used a slow computer a couple years ago that I could not jump as high, and my characters movements looked choppy from everyone else's vantage. I was also using build15 at the time; when I upgraded to build16 it fixed the problem. So I'm not sure if that's your issue.
When does or where does a FPS skill set become a winning factor? I find those games much more full of machismo.
Then just play those games. Why should DP2 copy all of their styles?
