so I have a ryzen 2400g and an rx 580 in this system
both vulkan capable
for whatever reason, doom renders on my vega in my 2400g and outpu

I believe that's the loader (in src/loader) - nothing radv specific. It's
annoying for GL purposes too, with DRI_PRIME=1 picking the *last* GPU instead
of the second.
It used to work this way, but then the l

I have the same problem using DXVK, and there is a similar bug report on
vkmark:

It seems that there is something in the RADV driver that causes GPUs to

So I think there are several issues in this bug:
1) Running on a GPU that is not connected to the display is slower. Arguably we
should be able to optimize this a bit, especially if the two cards are

There is extra overhead when using secondary GPUs in conjunction with prime
when you want to see the results on the display. The display is only attached
to one GPU so when you render with the other GPU, the

This probably goes without saying, but OpenGL and OpenCL apps does not have
this issue. They will run on the GPU or GPU's I expect them to.
For example, 'ethminer --opencl-device 0' will run on my primary whil

I wonder if that's a bug in the PRIME code, I wouldn't have expected to see a
drop in FPS that much if the cards are identical. Out of interest, do you see
differences at other resolutions?
