The oil refinary has some serious lag / frame rate issues. Its not the best map, but it is larger allowing more sniping to take place. Please fix. Anyway, thanks for listening to us. Im really enjoying the new patch.

Agreed. Oil Refinery definitely has some form of memory leak.

I'll be playing and all of a sudden once this map comes up and I play a round on it, I alt tab out and my PC usage spikes up to 50% or some such, PageFile doubles as well.

This should have been fixed in the first patch. This is the exact kind of thing testers should catch if they know how to playtest.
