I have set up wpe for gstreamer wpevideosrc on Ubuntu 22.04 on a laptop with a base gpu (intel) and addition GPU nvidia 2060 (m).
I am getting different results depending if using wsl2 from win 11 or native Ubuntu 22.04
standard cmd for all tests LIBGL_ALWAYS_SOFTWARE=false gst-launch-1.0 --eos-on-shutdown wpevideosrc location="https://webglreport.com/" ! videorate ! video/x-raw,framerate=50/1 ! videoconvert ! video/x-raw,width=1920,height=1080,framerate=50/1 ! ximagesink
WSL2 (win11) - reports using apple - but actually using nvidia GPU as expected
rendering https://www.kevs3d.co.uk/dev/shaders/distancefield8.html generates 50FPS as expected if changing LIBGL_ALWAYS_SOFTWARE=ftrue, then FPS = 1
**So WSL2 is using the GPU as expected
Ubuntu 22.04 native (same laptop)
right image shows firefox report GPU being used rendering https://www.kevs3d.co.uk/dev/shaders/distancefield8.html generates 50FPS as expected
prime-select query => nvidia nvidia-smi: NVIDIA-SMI 535.113.01 Driver Version: 535.113.01 CUDA Version: 12.2 lspci | grep VGA 00:02.0 VGA compatible controller: Intel Corporation CoffeeLake-H GT2 [UHD Graphics 630] 01:00.0 VGA compatible controller: NVIDIA Corporation TU106M [GeForce RTX 2060 Mobile] (rev a1)
I have also tried prime-select on-demand, but this was the same result is there a flag or way to force wpe to use the GPU in native the same it it does via wsl2?
