Is it possible to utilize more than one graphic card at the same time with windows?
If so, how?
I do not want to use SLI which is handled transparently by the driver. I want to control each graphic card separately, through a separate context.
Yes, you can use multiple GPUs with windows.
- Connect atleast one display to each GPU
- Create 2 windows (one on each display).
- Create an OpenGL rendering context for each window
- Make the rendering context current of the window (GPU) to which you want to draw to.
Alternatively u can create 2 threads and make one context current in each thread and issue the draw calls.
Furthermore, there is an NVIDIA extension to do that through OpenGL (WGL), WGL_NV_gpu_affinity. Yet, the spec hasn’t been seen round…
