* This can't be a CPU bottleneck because CPU utilization is between 40-60%. Also if it was a CPU bottleneck then I'd have the same or similar frequent low GPU usage and low framerate issue while GSYNC is disabled but I don't. If I disable GSYNC then the issue disappears.
* I don't have Fast Startup option. Probably because I've disabled hibernation with "powercfg -h off"
* I'll try GSYNC + V-Sync (NVCP), low latency mode and fps cap next time and report back..
