This Benchmark ver. 2021.2.18.0 used CPU between 3% – 15% (Benchmark is currently not limited by CPU performance).

my 1650 (non super) unfortunatley refused to start the benchmark 🙁

Thanks for your scores.
Question: how do you measure the GPU usage?
Looks like you use Windows task manager. In that case you have to look at the Graphics_1 sensor, not the 3D one.
