Add reference to: OpenGL.Net\OpenGL.Net.WinForms\bin\net461\Debug\OpenGL.Net.WinForms.dll OpenGL.Net.WInforms
Open Form1
Add GlControl
Build
Run on dedicated gpu
Result:
On start, application lockup with high CPU usage.
Attaching with debugger and breaking shows that the application is stuck in:
GetGLProcAddressWGL.GetProcAddress(string function)
Argument function is "wglGetGPUIDsAMD"
This was tested on a laptop with an Intel GPU and dedicated Nvidia GPU (GTX 1070). By default, the application uses the Intel GPU and runs without issues.
