Hello. I have this new PC: CPU: I-5 2500 (without the 'k') @ 3.3Ghz GPU: ASUS GTX 580 direct cu II overclocked to 878 Mhz Motherboard: Intel DH67CL RAM: APACER 8GB DDR3 @ 1333 Mhz I was trying to play Rome: Total War (a game made way back in 2004) at max settings and at 1600x900 resolution (which is the max resolution of my monitor) and I get an average framerate of 20 fps, often even lower. So I checked GPU usage during the game, turns out it never reached 20%. But when I lowered the graphics settings, the fps immediately jumped to 60. As far as I can tell from task manager, there seems to be high CPU usage during gaming, but it doesn't tell how much exactly. So does this mean higher graphics settings require faster CPU clocks and not just a faster GPU? Or does it just mean there's a stability problem with my PC that's affecting its performance?
