Insane GPU usage even at low settings with high end computer

I had the same problem, I set my screen to 120hz instead of 144 (it give me 120fps max). Gpu load was less massive but still it was not quite ok. But with the today patch I think it's ok because I have no longer 90-99% gpu load but 33-75% load (60% most of the time). So sometimes my 2080ti set to Idle while gaming x)
