CPU: 12400F, GPU: B580.My operating system is Windows 11 24H2, and the graphics driver is the official 8629 WHQL version.

I'm experiencing the same issue on my end: OpenGL reaches up to around 800 fps, while Vulkan only hits about 400 at most.

However, I also noticed that your GPU doesn’t seem to be working properly in snapshot2, with only 2% utilization.

My situation seems a bit different from yours. In snapshot1 and snapshot2, the frame rates under the Vulkan API don’t show much difference, but in snapshot2, the frame rate with the OpenGL API appears to be significantly higher than with Vulkan (in the same scene, Vulkan API gets around 400 fps, while OpenGL reaches about 800 fps). I’m not quite sure what’s causing this. CPU: 12400F, GPU: B580.
