Reinstalled with fresh dload from MWLL site today. Started off on extrem with solid FPS, 60/70 with a full server at 18/20 ppl. No CCC installed at the time. Game ran pretty solidly all extrem with drops down to about 40 during fairly hvy action sequences. Went onto frostbite after this, fps was stable at around 60, to start with. As the match went on, FPS started to drop to <30 in combat. Then the icing on the cake, took out a puma and went up against an owens, it shutdown and I flamed it with my 2 flamers, FPS clocked in at 9 at this point.
There's something going on guys, It's obvious. I run crysis benchmark with average 60fps on both CPU and GPU test no problems. However it seems to be tied in to assets, when a new asset in purchased somewhere in the game my game suddenly locks up for a second and then re-engages, but my fps seems to have taken a small hit after this. The more assets that get bought, the more my FPS drops.
It screams memory problems to me in all honesty. I've monitored my GPU and CPU heat and noticed no difference in heat levels between periods of high fps and low fps.
PS reinstalled CCC and no noticeable performance increase/decrease.
