Windows 10: high GPU usage when run Yolov5 on win11

We have an AI application based on Yolov5 cuda. It works well but suddenly found it took high GPU resource than before.We test on the same PC with RTX4060 with same driver release.When install Win10 and Win11 21H2, the application works well only take about 5%-10% GPU.But when update or re-install to Win11 22H2Win23H2Win24H2 the application takes more 40% GPU, even to 70%.Already try to disable "Hardware-Accelerated GPU Scheduling", but no improvement at all.Please help, we don't want to rollback PCs from win11 to win10.

Desktop Windows Manager high GPU usage persists

Several individuals have reported Desktop Window Manager (dwm.exe) using unrealistic amounts of GPU for video playback, gaming, or any high graphics intensive activity. Here is a list of just a few of the many requests for support on this issue:

Example 1

Example 2

Example 3

Example 4

Example 5

It has been a few years now that this problem has been reported, are there any accepted fixes. From what I gather, even those individuals with serious graphics cards are vulnerable to dwm.exe dominating their available GPU. I myself report this issue, even
on games and design software with the settings at a minimum. For example, Java will be using ~45% of the available GPU, whereas dwm.exe takes up the remaining ~55%. As stated previously, the result is the entire system halting, not just the game. The mouse
will take a few seconds to stutter across the screen, and task manager will take 5+ seconds to even appear.

There have been many suggestions and no results. Is that Microsoft's consensus then? Thank you ahead of time.

 

Roblox low gpu usage issue

Thanks for reaching out! I'm an Independent Advisor and a Microsoft user like you.

Thank you for providing detailed information about your issue. To better assist you, I have a few additional questions and suggestions:

1. Other Games: Could you specify which other games you are able to run without any issues? This will help us understand the performance demands in comparison to Roblox.
   
2. Temperature and Usage: Please check your CPU's temperature and usage while playing Roblox. Tools such as HWINFO, MSI Afterburner, or similar can provide this information. Overheating or throttling could potentially cause the FPS drops you are experiencing.
   
3. Testing Steps: You've already tried several troubleshooting steps, which is great. However, considering the following might help narrow down the issue further:
   
   • Check for any dust buildup or insufficient cooling that might be affecting your GPU's performance over time.
     
   • Monitor the GPU usage and temperatures to see if there are any unusual spikes or drops when the FPS issue occurs.
     
4. Power Supply: Your 320W PSU might be on the lower end for your system's power requirements, especially under load. Even though you've tested with another PSU, ensure that it is of a higher wattage and quality to rule out power issues completely.
   
5. RAM and SSD: Since you suspect the SSD or RAM might be causing issues, consider running diagnostics:
   
   • Use tools like MemTest86 to check for any RAM errors.
     
   • Perform a thorough check on your SSD health using tools like CrystalDiskInfo.
     
6. FPS Unlocker: While you mentioned that the FPS Unlocker isn’t the issue, try running Roblox without it to see if the problem persists. This can help rule out any software conflicts.
   

Please share the results from these tests, especially the CPU and GPU temperature and usage statistics, as they will help in diagnosing the issue further.

 

Low gpu usage in roblox and gpu usage dropping

I can run other games with quite normal GPU usage like 30 - 60 CPU Usage and 70-100 GPU Usage in other games but I noticed that I have other games on HDD disk and Roblox on SSD disk and I was wondering if this might be Disk issue. On the one of screenshots at UserBenchmark results that says to plug in SSD disk into SATA 3.0 port with SATA 3.0 cabel. My problem is low GPU Usage in roblox but in some cases I have pretty high gpu usage and then it drops from like 50% to 20%.

I forgot to add that I have ddr3 ram 1333Mhz
