I’m getting 100% gpu usuage in the Unity Editor while my scene is near enough empty. I don’t want my graphics card to be hammered this hard all the time for no reason.
I’ve spent a few hours researching with no results to show.
I’ve tried this:
Also tried switching to OpenGL & update graphics drivers, switching to lowest settings etc.
any other suggestions please?
I’m having the same issue.
Whenever I move camera in scene view or change the GUI in any way GPU usage jumps to 90+%. I tried it in many versions of Unity and it did it in all of them even in empty objects.
I’m running RTX2080.
Newest drivers didn’t help and I don’t think uninstalling Hub is the best possible solution.
Same for me. I run 3 1080 GPU cards and the two of the 3 running at 1700mhz - what’s going on Unity people
Before today, Unity ran fine. Though it started to lag and show high GPU usage when open and even maxing out my graphics card when moving around Editor windows.
A couple things I tried was to open Unity without the Hub open and also updating my graphics driver.
Since I did both of these at the same time, IDK which one solved it. But, my GPU usage is back to normal.
I do find it strange that this lag started happening out of no where today, this questions was posted the just other day, and more than 100 folks have followed this since then.
I’m using Unity 2017.4.28f1 on a GTX 1060 6GB.
Same thing here, Running Unity 2021 and whenever I right click on an editor window my CPU and GPU usage skyrockets, what gives?
I likewise experience high percentages of the GPU being utilized in the editor, but also for builts. I have looked into quality settings, lighting and vSync, but none of these make a difference. The GPU driver is also updated. So, is anyone closer to a solution?
Just to drop my 2 cents about this, since i’ve had the same problem, and resolution was kind of weird. Spent hours and hours on research about it and how its happening for me. My issue was so random, that no relation with hardware what so ever was possible. Sometime game would run fine for 2h, and sometime framerate would drop as soon as intro screen was playing. Just by accident, stumbled upon program called Nvidia Inspector and noticed Performance State monitoring there, and to my surprise…every single time framerate dropped and GPU usage went to 100%, GPU performance state changed to P8, and that is supposed to be used on Windows idle and lightweight GPU workload. After manually placing unity exe file into Full 3D Applications and compiled game binary, issue was gone.
Those GPU performance states are supposed to change automatically upon GPU load, but i guess something in windows is resetting it.
I don’t think this is related to Unity at all, something in Windows is triggering changes on GPU performance states and most likely what you see in editor and build is aftermath of that. I’ve never experienced this issue again after manually setting P0 states for unity editor and game build.
Root cause was never found, but my suspect is AMD platform, since i’ve switched to 5900X. On Intel platform, this never happened.
Idk, maybe this helps someone…
I’m using Unity 2021.3.3f1 - and when in the Editor, no matter what I set “targetFrameRate” to (e.g. 10) and no matter how little content I have in the scene, Unity is using up 11% of CPU (which is 100% of one of my CPU cores) and 50%+ of the GPU! (I’m on a super PC, 12th Gen Intel I7-12700K 3.6 GHz, with AMD Radeon RX 6600 XT, with 32 GB RAM).
On this PC, Unity will accomplish a GREAT DEAL of shading. But the issue here is that even when I give it NOTHING TO DO! (empty scene, Camera turned off! TargetframeRate = 10) - the GPU usage is still 50%!!! and CPU 11% (100% of 1 core)
I’d really like it if Unity didn’t HAMMER my GPU/CPU with NOTHING TO DO. WTH is it doing???
I’d also like the good feeling of knowing “I’m having it do ‘X’ which consumes 5% of my GPU” which then allows me to extrapolate.
Here’s a screen shot of the Profiler, showing CPU dedicated near 100% to OTHER TASKS, and GPU with NOTHING TO DO (I have camera turned off).
But here is my Windows 11 Perf manager, showing CPU at 12% (100% of 1 core) and GPU at 37% (with NOTHING to do at all!).
Hints anyone?
Did anyone find a solution for this?
