New issue

I used to have a hitching problem until IronHorse helped me out. But now I have a more serious problem. It could be the hardware as its not amazing hardware but I've only had this problem for the last month or so. My specs: (yes, its laptop)

i7-2630QM 2.0 GHz (Turbo Boost 2.6 GHz)
nVIDIA GTX 570M 1.5GB DDR5 (latest drivers)
12 GB RAM

I run at 1280x720 resolution with everything off or minimal. While in the ready room and during "normal" gameplay, it is normally around 120-140 fps, but randomly it drops to anywhere from 15-40 fps for about 15 seconds even in the early game, making hide and thus not helping my team. I expect fps drops as its normal but not 100 fps. Any advice would be great. Thank you.

Oh, BTW, I dont believe it happens at all when playing in a combat mod server. While in a combat server, the fps range from 90-150 at times. I'm curious as to why.

EDIT: Here's a few screenshots with the profile enabled.





As you can see, the fps drops become worse the longer the game lasts. When I first joined the game, the bars were red and very small. Then, that. ^^
