Strange GPU behavior? Tags: GPUs Games Graphics Last response: January 5, 2014 8:14 PM in Graphics & Displays Share Fred5612 January 5, 2014 3:04:53 AM Hello all, I just took this screenshot http://oi44.tinypic.com/mufk5.jpg with MSI afterburner, ran the test with the game "Tomb Raider", but it happens with pretty much any game. I was wondering how come the GPU 1 usage was so smooth while the GPU 2 usage so ragged. What could be the cause? Does this affect performance? I'm running two GTX 680's in SLi Thank you! -Fred More about : strange gpu behavior ewok93 January 5, 2014 3:23:42 AM Shouldn't affect it, it's probably just the main one handling most of the load. m 0 l ShadyHamster January 5, 2014 3:26:45 AM Your screen shot shows gpu 2 power % and gpu 1 % usage. Scroll down to show gpu % usage for both cards. m 0 l Related resources Strange GPU Behavior - Forum Strange behavior with pc, want to see if it is caused by motherboard. - Forum Hard Drive - strange behavior - Forum Strange behavior after installing a new HDD? - Forum Strange external HDD behavior - Forum Can't find your answer ?

Running two cards in SLI doesn't mean they take on the exact same load. m 0 l ewok93 January 5, 2014 3:27:53 AM Ah I missed that. ShadyHamster is right. m 0 l unknownofprob January 5, 2014 3:29:17 AM ewok93 said:Shouldn't affect it, it's probably just the main one handling most of the load. In SLI, both GPU's should be scaled to around the same usage but not always, 60 and 40 % is quite normal what do you mean by ragged? m 0 l Fred5612 January 5, 2014 6:22:33 AM Ops sorry everyone, here is GPU 1 usage vs GPU 2, how come they are so different and GPU 2 is so erratic? http://oi43.tinypic.com/155temv.jpg m 0 l ewok93 January 5, 2014 11:29:17 AM Err.. They're the exact same. They're the bottom two in the screenshot. m 0 l unknownofprob January 5, 2014 8:14:25 PM Fred5612 said:Ops sorry everyone, here is GPU 1 usage vs GPU 2, how come they are so different and GPU 2 is so erratic? http://oi43.tinypic.com/155temv.jpg GPU1 and GPU2 % Usage is exactly the same as mentioned before. The Rest is similar to the other GPU just minor differences which is expected in SLI m 0 l Can't find your answer ? Ask !
