How can i see if my cpu is bottlenecking my gpu?

DarkDubzs · Nov 25, 2013

So im pretty sure my 6800k is holding back my GTX 660 sc, but i want to make sure. Someone said its as easy as just opening Task Manager while youre gaming and if it shows the cpu is at 100% and the gpu is lower then the cpu is bottlenecking the gpu. So i tried it right now, but i just remembered there is nothing in TM showing you what your gpu load is. So i would like to know a good, free, easy to use program that shows my cpu and gpu load. What is a good program for that? Any help, recommendations, and advice is welcome. Thanks!

Open Hardware Monitor. http://openhardwaremonitor.org/

Is that the same as HWMonitor with the red icon? I already have CPU-Z which doesnt work for my goal, and HWMonitor which i dont like to use because it keeps working in the background unless you end them in Task Manager processes.

No, it's a different program. It actually closes when you close the window; you don't need to end task it in task manager.

Neither of them show the load of the cpu or gpu

Open Hardware Monitor definitely shows CPU and GPU load. I use it all the time.

Sorry, i was derping. Yeah it works great, but how am i supposed to see the percentages while i am playing?

Unless you have multiple monitors, you can't really. However you can turn on plotting and have it plot CPU/GPU load. Then play your game and then exit/minimize it to look at the plot retrospectively.

How do I turn on that plotting thing you're talking about?

aznricepuff · Nov 26, 2013

View -> Show Plot.

Then check the sensors that you want plotted.

So i did the plot thing with Open Hardware Monitor and was playing Far Cry 3. Shows that all 4 cores were around 100% and the gpu was around 50%. Seems like a tiny bottleneck to me...
