Excilium, that issue is unrelated to this one. I never connect to a server with a higher ping than 90 in any game. This problem excists in both MP and SP, atleast in my case, and I think quite a few others. Me and my friend made a server with only me and him on, switching between who hosted, but I still got massive lag.
SGTIce, in which way is dxdiag going to help, to upload PC spec's or?
Disableing post processing works very well, and makes the game playable. But still hoping they'll fix it soon.
Thanks to Roytjb and Rick, for sharing this usefull information and solution.
