Whenever i play say....team deathmatch, upon the round start, and my first encounter with an enemy, the framerate would take a severe dip. Later on it's okay. The thing is, my first one or two encounters often lead to my death because of the dip. I'm getting >60fps at any other time.
It's like my card needs to warm up and during the first encounter, it's not at full throttle, pretty much like how there is always framerate dips when the stage loads up.
same problem with 7970 GE 13.2 B6
it is just one time at the begin, it is just like a hang of a sec, then no more drop
usually >100fps
