Hi,
on start project I have this warning.
<<d3d12: Profiler is enabled, but stable power state is not. GPU timing errors are expected.>>
No errors ,drivers update, windows build and DX12 ok CPU i7 3770,RTX 2060.
All GPU usage in play mode is used by DWM.exe and Unity editor is only using CPU
FPS is low on simple scene.
I trided two systems same result.
Any help??
Thanks,
Did you try to investigate with the help of the Profiler what is eating for framerate?
I also use DirectX12 and RTX 2060 for one of my projects and it a more complex scene than yours by telling from the screenshot. Still having over 60 fps.
Yes, there is only other using GPU, there is a warning on GPU which i don’t know why.
With your RTX2060 what is the CPU for that system?
Ok, there are alot of spikes on your CPU usage. You should check out what is causing them. Can you hover above the yellow explamation mark icon beside GPU usage? I never saw that icon before.
By the way, I’m using a Intel Core i7-9750G @ 2.60 GHz and I have 32 GB ram.
Hi,
Yellow exclamation I don’t know why it is there for. The scene is not using the GPU, if a go to Task manager GPU is not in use.
Here same scene on a new system i9700 RTX 2070 I get 101FPS instaead of 20FPS but almost all from the CPU.The only thing on the GPU is the Shadow depth. Maybe it is using it and not showing, because a have post processing in the scene.
I’m not sure, but I think I have the same issue,
I have a RTX2060 with a AMD cpu
Bellow is the exact same scene running on the same computer, within the same but branch of the project.
Left is Unity 2019.3fb11, right is unity 2019.2.11.
If you look at the legend on the left side of the screen, you’ll see that the ugly olive-green part of the CPU profiler that’s causing the actual spikes are GC. So you’re puking allocations all over the place.
The GPU is just stalling because your CPU is stalling at the same time.
To see GPU profile go Profiler Modules top left, to activate GPU display.
GPU is just not activate on is display. I have a Yellow Exclamation mark on GPU I don’t know why.
I came across this thread because I started getting the same (d3d12: Profiler is enabled, but stable power state is not. GPU timing errors are expected) warning message at project startup.
I also have the yellow exclamation mark against GPU Usage in the profiler. Looking at the docco at (Unity - Manual: GPU Usage Profiler module) it mentions:
Given this I tried:
I am using a Windows 10 development workstation, 12Mb RAM, 2019.3.13f1, URP 7.3.1, D3D12 (needed for Crest Ocean System to work with XBox deployment), GTX 1050Ti, . Using the latest GeForce driver (445.87) - also tried above with Studio driver but made no difference.
While I would like to have access to the GPU Profiler my main interest is knowing why the stable power state message appears and what this means…
Any suggestions for resolution would be much appreciated.
To avoid this message and get comparable GPU timings, you can pass -force-d3d12-stablepowerstate as cl flag to the editor/player. It affects performance but provides stable measurement results by making sure the clock settings are the same between runs.
The yellow warning triangle next to the GPU Usage Profiler legend has been there forever, but it has moved from the bottom to the top in 2019.3. With that change, the tooltip broke. A fix for the tooltip should be in the next 2019.3 release. The warning there is to alert to the fact that having an active GPU Profiler Module while profiling can have a big impact on the performance of the profiled application, which is why the module is not added by default and adding it isn’t retained over multiple editor sessions, to avoid accidentally lowering performance due to leaving the module on unintentionally.
Additionally to that warning, the GPU Usage Module’s chart should show warning triangles if GPU profiling does for some reason not work with the targeted application (e.g. because Graphics Jobs being enabled or because the specific Graphics API is not yet supported for GPU profiling). If you hover those triangles or select a frame without data and and check the details below the charts, the Profiler should tell you the reasons for there not to be any data.
If there is no data and no message as to why, that’s a bug, please file a bug report.
Regarding why unity is not using the GPU? I got nothing, sorry, not my field of expertise. But this sounds like you might want to file a bug report?
Martin,
Thank you for your prompt reply and for clarifying the meaning of the console warning message.
In my case I think the GPU is working (I am not seeing any additional warning triangles) - I just have the one that is currently missing a tool tip.
As an aside, I think it would be really helpful if the clarifications you have provided above could all be added to the GPU Profiler documentation…
Cheers, S
Thanks for bringing that up. We’ll update the documentation 
For whatever it’s worth, the tooltip is also absent in 2020.1.0f1.
hi everyone, i have the same problem but just after i updated my project from unity version 2020.1.16f To: Unity 2020.2.1f, now, unity is so slow and giving me even 7 FPS but, if i close unity and than opening it again, it work good but after 2 min , it’s getting slower every time 
.
i’m using HDRP 10 on windows 10 , i5 - 9400f _ RAM : 16 _ VGA: RTX 2060 OC
also GPU profiler is not working and showing the same error the guys up says …
thanks <3
fixed Issus by just move DX12 to down, now unity runs with DX11 and it’s working fine, but point is why DX12 is not working fine ?
I don’t know but please report a bug.
I’ve the same issue. Is there a solution ?
I don’t know if this was ever reported so no idea. Likely not a bad idea to report a bug on this.
I just reported.
