FX 8120 @4.2Ghz bottlenecking a GTX660? Massive dips in FPS

post #1 of 3
Thread Starter 
Like the title says, I'm having mostly low FPS on every game i try, and was wondering if someone could help me figure out what the problem might be?

Games like Starcraft 2, Tombraider, Crysis 3 and Bioshock infinite all are all nearly unplayable at higher settings. I have tried downloading the G-force experience software to auto-detect and set optimal settings for these games, but even than I get massive dips in FPS every few seconds. Games just feel generally really laggy. When i make turns in first person shooters like crysis, i get insane lag-spikes, the game kinda just freezes for a second or two.

I'm running a fresh install of windows 8 64 bit, and all drivers and BIOS are up to date. My brother has a much weaker CPU/GPU combo, but gets mostly higher fps and fluid gameplay on games I'm struggling with. It seems like there is no difference in fps when this CPU is OC'ed and at stock settings. I used to have ATI4890 before i got the GTX660, my benchmark scores are much higher now, but like I said, no game runs smoothly without hiccups.

The image below is after a few minutes of Crysis 3. Anyone see something wrong?

Windows 8, 64 bit.

turn off v-sync you don't need it if your fps are low. that might help a little.
turn down AA a little bit, i cant remember but i thought i read that the gtx 660 doesn't do anti aliasing well.
whats your monitor resolution. if its real high that could be whats affecting your fps.
this site has some recommended settings for game for your card with different resolution settings.

hello,
it could also be you cpu is down clocking in between work loads while the game is running, leaving you with drops in frame rate.
go to control panel, system and security and then power options and change to high performance.
