Actually i may try to run default bios settings after a clean, been overclocking for years and i have used MSI Gaming App alot with several MSI GPUs. That might be it.
I will also eliminate alot of background processes, but one thing: This is competitive gaming and not public servers, it comes after longer than 40-60 minutes i believe. Even if it's regular matchmaking, Faceit or Esportal for example.
Getting back to you guys later.
