To be honest i can't tell. LatencyMon still showed really high latency and the ISR and DPC count was still really high but i don't think i can't make out any more glitches, especially the visible glitches stopped appearing. I would probably not have checked my cables and would still be out there in the internet trying many different things. Thanks a lot, i appreciate what you are doing. I think this can be marked as solved <3
