You should btw. also set CPU clock governor to either acpi-cpufreq performance
or intel_pstate performance, since governors like powersave, ondemand or
schedutil can already cause severe stuttering at vsynctester.com, even without
a compositor.

The result should be 100% stutter free, at least that's the case for me with
amdgpu.dc=0. This way you should be able to be absolutely sure if the result is
badly affected by amdgpu.dc=1.
