I dont know what it could be...I got terrible FPS on Black ops (35-40) and its choppy as hell. My own build. Tried 2 different cards with same exact lag. My CPU? How do i show you my screenshot of the GPU Z?
Windows 7 Enterprise Gigabyte MA785GM-US2H AMD Phenom II 940 3.0 Ghz Quad core ATI HD Radeon 5770 2 X 2g G.Skill Dual Channel DDR2 401.8 MHz (1:2) @ 5-5-5-15 320 GB Western Digital
More aboutsame choppy video cards
I also just put in a new motherboard today. (Same Model)
Your gpu has a 128bitrate a bit weak. My guess is try lowering the setting. You should be getting atleast 60-80fps with that cpu.
Other card was the Nvidia GTX 460, and i got the same lag on the lowest resolution and the highest resolution...it dont make a diff. Thats wuts making me think its the processor....because I tried a new card and I also have a new motherboard.
Well im here to find out how to narrow it down....any suggestions?
