The problem manifesting under low load would explain why I cannot replicate the
problem while running Unigine Superposition.

I began to wonder if powerplay and the frequency at which the chip and memory
were operating were not the problem after reading the following bug report for
Vega 20:


Last Friday, I attempted to capture the operating frequency and temps, but my
attempt utterly failed.

I will disable v-sync and see if that improves and report back here.  If I
manage to capture frequency data, I will report back here and may be your
