Posted April 25, 2015 I have 2 titan xs in sli and I get poor gpu utilization is games. Sometimes it drops down to 50% for no apparent reason, as there is no cpu bottleneck (I'm running 4970k). What would be causing this poor gpu utilization? I have: 4790k overclocked to 4.6ghz asus maximus VII forumula mobo Corsair 1500i psu 16 gb ram titan x sli nvidia surround at 7680 x 1440 It's pcie gen 3 8 X 8, due to the z97 issue. I was told this wouldn't be a problem, but maybe it is? Somebody else on the forum said the titan x should run fine off pcie 8, is that true?

Posted April 25, 2015 It's not a PCIE bottleneck. What game are you playing? Many games are very poorly optimized for SLI, and if so the second card will be hardly used, if at all.

Posted April 25, 2015 Author It's not a PCIE bottleneck. What game are you playing? Many games are very poorly optimized for SLI, and if so the second card will be hardly used, if at all. it's happened in multiple games. GTA V being the latest. I run msi afterburner and both cards are being used Link to comment https://linustechtips.com/topic/354936-gpu-utlization-is-poor/#findComment-4821042 Share on other sites More sharing options...

Posted April 25, 2015 Somebody else on the forum said the titan x should run fine off pcie 8, is that true? Very true; there is still ample bandwidth. Is Vsync enabled?

Posted April 25, 2015 Do you have v-sync enabled or capped fps somehow (Afterburner / precisionX and so on have this feature) PCI-E 3.0 @ x8 probably be saturated if your trying to run them full blast.. A GTX 690 just about saturated PCI-E 2.0 (About a 4% difference from x16 to x8 in that case as 3.0 is doubvle the bandwidth of 2.0) but you should get past 50% usage even before you saw an effect. I don'T PreSS caPs.. I juST Hit THe keYboARd so HarD iT CriTs :P Quote or @dzzope to get my attention..

No v-sync isn't enabled. It's runs at full speed sometimes, but not always. It just at certain times, which appear random that the game uses like 38% -50% gpu utilization. This happens at 1080p and 6K. It doesn't matter the resolution Link to comment https://linustechtips.com/topic/354936-gpu-utlization-is-poor/#findComment-4821099 Share on other sites More sharing options...

Posted April 25, 2015 Author The fps obviously dip when the gpu utilization goes down. So it's not a vsync issue (as I have that turned off).

Posted April 25, 2015 Author I just ran 3d mark, and my gpu utilization on both cards is near 100% (98% and 96%). I don't know where the bottleneck is coming from with these games <sigh> Link to comment https://linustechtips.com/topic/354936-gpu-utlization-is-poor/#findComment-4821176 Share on other sites More sharing options...

Posted April 25, 2015 Download DDU, uninstall the graphics card drivers then reinstall.

Posted April 25, 2015 Ok, I'll try that. Thanks I can't guarantee it will work, but this is the nature of troubleshooting; you try potentially relevant solutions.
