100% GPU Usage

Development Platform & Builds

Hey,

My GPU is constantly under 100% usage in my packaged game.
Does somebody knows where I could look to probably find the problem?
I checked GPU Profiler, but there is nothing special. I also deleted my Savefiles, but this wasn´t the solution.

Maybe somebody has an idea.

Best regards

what gpu? whats your game like?

without information all we can assume is that your trying to run a realistic poorly optimized game on a potato.

also the profiler should tell you quite a bit about where resources are being allocated.

If your GPU is under 100% usage it means that something holding up GPU and it really does not need to be bad thing. There few possibile reasons

  1. Framerate limit, like VSync or t.MaxFPS setting will reduce load on GPU and it will show GPU usage under 100%
  2. Your code aspecially on tick event is too heavy so CPU is bottle-necking GPU, if thats the case you can try negativing blueprints. In that case it is CPU issue not GPU
  3. But it might be opposite, your game run so fast on GPU that you hitting your CPU performance limit… so CPU bottlenecking the GPU again :stuck_out_tongue:

GPU usage does not matter as long as you match your performance target, if games perform well under 100% thats actually better for user as your game don’t put stress on GPU. So check other parameters before jurging situation. Keep in mind that Shipping build can run faster then Editor or Development build with debug tools.

I’m having the same problem since updating to 4.19. I have a Titan X (Maxwell) and it’s under 100% load all the time, regardless of map.

I am having the same problem. 100% of gpu in empty level. It is fine in the editor.
