I have two monitors connected to two different GPU's and I would like the load to be splitted like they are connected. The problem is that is not the case, everything (Video decoding) is calculated by main GPU although it is displayed on second monitor. There are many similar problems in the internet, yet none addresses problems I have.

The outcome I would like to achieve is impossible as far as google questions refer to, although maybe some software can achieve this?

The exact problem I want to refer in this question to is related to selecting which GPU to use per app. This solution would be enough if not for the fact that Windows says the best GPU for power saving and max performance it the same GPU, not allowing me to use any available solution to the problem.

So, I want to ask two questions:

  • is it possible to enforce rendering with GPU that monitor is connected to?

  • can I manually tell Windows which GPU would be better for power saving or another profile?

Edit: my graphic cards are GTX 1060 and GT 730, one monitor connected to each GPU.

  • I think you're trying to apply concept/procedures of a laptop with hybrid iGPU+dGPU to a desktop with 2 dGPUs. It isn't applicable and with such setup it makes no sense to speak of "power saving". The GTX1060 has surely the higher performance and likely also the better energy efficiency so Windows is right.

  • I undestand your reasosing and that is absolutely correct, but that does not address the question. I have the real need for a feature/capability I described and yet I cannot find solution for that

  • If you have a real need (LOL) for such feature use a laptop with hybrid graphics.

This similar question has an answer, of sorts:

Windows 10; Manually select power saving and performance GPU

Summary: Windows 10 Insider Preview Build 20190 has options that will address this.

  • Although I accepted this answer, this is not in Windows (normal) release yet

  • Update: This is supported in Windows 11 (only external links available) - windowslatest.com/2021/06/23/…
