<pre>Hi, I've run into this issue with DOOM 2016 recently:
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 outputs to
whatever display i have hooked up
which is why i was only getting 20-30 fps on like medium settings with my RX
580 set as my primary gpu in bios.
the only way I was able to get around this was to go in my bios and completely
disable the integrated graphics
Once I disabled the 2400g's igpu, my framerates returned to normal with my RX
580
Tested on both llvm-svn and mesa-git as well as llvm 6 + mesa 18.2</pre>
