I tried using a compute shader in my project and got the error “Compute Shaders are not supported for OpenGL on this platform.”
To rule out any issues on the part of my PC, I updated my drivers and confirmed that my PC runs OpenGL 4.6. I think it should run compute shaders without any issue. I will use compute shaders with a C++ library to confirm that compute shaders work on my PC.
Note: Windows 11 not 10 as seen in the image.
I thought to print out graphics.adapter_info()and saw that there is an issue with compute shaders in the engine.
the adapter info returns

},
....
In the limits table, everything related to the compute equals zero which explains the error.
max_compute_workgroup_size_y = 0,
max_compute_workgroup_size_z = 0,
max_compute_workgroup_invocations = 0,
max_compute_shared_memory_size = 0,
This seems to be an engine level issue.
Has anyone else encountered this issue?
