After the game update today I play some coop and versus.
I had a bad performance experience in coop on Ministry and Outskirts. The fps were about half the usual. I think there's some kind of bug. This problem only seems to occur in coop mode.
In versus, the performance was very good but with some stuttering or frame drop sometimes.
I also played Local mode in Refinery the performance was very good too.
My Dxdiag just in case.
P.S. I didn't like the Domination. The respawn wait is too short and this way nobody cares about to die.
