|Project:||The Open Toolkit library|
Tested on Windows, going to test on Linux soon. Laptops that have an NVidia Optimus GPU ("auto"-switching between discreet and integrated GPU) use the integrated GPU for OpenTK applications when they should be using the discreet GPU.
From what I've read about the issue, a quick-and-dirty fix is to invoke a small piece of CUDA or DirectX code to switch to the discreet GPU on Windows, there's probably a better way to do it though. I'll do some digging around and see if NVidia provides a nicer way to do this.
