WSL2 OpenGL D3D12 is being very slow

When I run glxgears in WSL2 Ubuntu with my NVIDIA GTX 1650, I get very low FPS

415 frames in 5.0 seconds = 82.836 FPS
367 frames in 5.0 seconds = 73.247 FPS
373 frames in 5.0 seconds = 74.504 FPS
371 frames in 5.0 seconds = 74.085 FPS
366 frames in 5.0 seconds = 73.052 FPS

WSL2 is definitely using my GPU, as my CPU llvmpipe glxgears is ~1000 FPS

VSync does not seem to be the issue, as this also occurs with vblank_mode=0

On normal Linux with my GPU, I get around 2000 FPS in glxgears

es2gears is also slower on my GPU than my CPU

Does anyone know why this is? I get that D3D12 is a translation layer but surely it isn't that slow? Here is my system info
