I was playing COD:MW3 on a 1440x900 screen on my friend's PC
CPU PII x4 840
GPU XFX HD5770

I couldnt play it in ultra. got around 35-40 fps.. but during levels where there was lots of smoke fps dropped and it started lagging. so i OC'ed the card to 890/1275 (stock is 850/1200) using CCC and the game is running fine at 40+fps.

Is my friend's card underperforming cuz i saw that HD5770 can play MW3(Ultra) at HD resolutions. And by ultra i mean everytihng maxed out AA, SSAO and all

Thank you :-)

Depends on the CPU too. With a litlle overclock to the CPU you will gain another few FPS on the game.

I don't understand, who's graphic card is having the problem? Yours or your friend's?

No, it is not underperforming assuming your CPU is Phenom 840. Overclocking will probably solve your problem. Try overclocking to 3.75 with stock coolers or 4 Ghz with aftermarket cooler.

It's probably the CPU. HD5770 can easily max out MW3 at stock.

My ATI HD5770 seems to be under performing also. Two system monitors (e.g. AMD System Monitor) are saying it's running at 400Mhz, and not the spec'd 850Mhz. Any idea what is going on?
