I have a laptop with hybrid graphics that needs both GPUs running in order to cool the system correctly, if the intel GPU is off then its fan does not run followed by my computer overheating. The problem is that I haven’t been able to get both cards running unless I use bumblebee, but it does not support vulkan, which I need for most of my games to work. I was able to get vulkan to work with bumblebee by using primus-vk, the problem with this is that primus-vk is very limited and I loose so much performance that it feels like I am using an intel 4000 card rather than a GTX 1060 even with my games on lowest settings.
I am getting really irritated because I have a nice GPU, but I am limited to the performance of a really low end computer. That or I burn myself playing followed by throttling and my computer shutting itself off to prevent damage. Is there anyway at all to have both cards running while getting decent performance and not sacrificing the ability to use vulkan?
