Default GpuOwl Nvidia Hardware Accelerated Scheduling Test (Windows)

With the newest Nvidia driver release on Windows along with the newest Windows update, there's apparently a new feature that is called hardware accelerated scheduling under the settings->display->graphics options menu, so I decided to run a quick and dirty test on it.



Without it enabled: one core of the CPU is constantly maxed out (overall usage about 5% on the 3900x)

Code:

With it enabled: CPU usage is way down to around 40-50% on a single core (or around 2% overall utilization on 3900x)

The speed up is seemingly negligible but the CPU utilization is way down, which could make the -yield option unnecessary.
