Gtx680 sli low fps - Page 2

post #11 of 26
Thread Starter 
well good to see some answers,

to clear some things up i have been testing the sli on bf3 for 2 day now , my FPS are never stable higest going to 80 FPS then dipping to 38 fps some times( make it unplayable below 40 FPS)...so i reduced the MSAA from x4 to x2 that improved the fps by 20 % . many people suggested i OC my 2600k so i did, i tried 4.5Ghz but my cpu tems got too high as im on air-cooling (cm hyper cooler).
then i reduced to 4GHz on the cpu OC which is stable giving me a average of 60 to 75 @ C temp on prime 95 for 1 hr test. on gaming it never goes above 65 C. still on bf3 im averaging 50 to 65 FPS and not higher some times it dips below 55 but never below 45 fps.

i have checked every thing else, and i cant put my finger on the problem, please guys help me out here...

specs are:

2600k @ 4 GHz
drivers are new
sli is installed correctly ( gtx 680 2 gb x 2)
just bought a new PSU : ZALMAN ZM850-HP Plus
8 gb vengeance RAM
asus p8p68 deluxe /gen3 mobo
ssd for boot and gaming
nvidia surround gaming on 22" 1080p 3 monitors


what am i doing wrong???

I mean, 60fps average on triple monitors seems pretty good, but i'm really not sure what your setup should be churning out.

A CPU is basically ignorant to the resolution whether its 640x480 or 2560x1440, it will push the same performance if not bottle-necked by the graphics card.

Have you tried running 3Dmark11 or Heaven Unigine DX 11 benchmark just to see if there should be any problems with the GFX setup ?

try switching to the optimal battlefield 3 play settings from nvidia's website. I know it doesn't give 60 fps according to their website since they aim for 30+ but with their resolution at 2560 by 1600 they say it should get in the mid 40's on just one monitor. http://www.geforce.com/games-applications/pc-games/battlefield-3/ops/Battlefield-3-NVIDIA-GeForce-GTX-680-OPS .


Another thing to add, if you are using vsync then you also need to turn on triple buffering in your nvidia control panel.
