I usually run piglit as last thing in the evening on my Vega/Ryzen 
system. That box has 16GB VRAM, 32GB system.

No idea what the piglit settings actually are since I'm using the Ubuntu 
package to update it. My script just runs "piglit run 
/usr/lib/x86_64-linux-gnu/piglit/tests/gpu.py ~/Temp/".

I have to confess that I rarely look out for regressions in the actual 
result, but rather look out for lockups or KASAN reports from the kernel 
in dmesg.
