I have a Samsung ultra wide screen, with a 5120x1440p resolution and a second screen, but its mostly unused. I also tried disconnecting the second screen, didnt help. So you dont think my network is a problem, especially regarding the fact that CPU and GPU usage goes down rapidly as the stutters occur, so mostly during the touchdown moment. I have an OMEN pc, so I cant acces the XMP settings in the BIOS. I already trief upgrading from 16gb to 32gb, but it ran at 2133Mhz and I wasnt able to increase it due to the fact that it is a OMEN pc.
Thanks very much for all the tips!
