Major frametime spiking during longer sessions of 1hr+. 100-300ms frametime spikes every ~5 seconds


I am having major performance issues with the game which I have otherwise never experienced. After playing for 1hr+, I will suddenly experience intermittent frametime spikes of 100-300ms every 5 seconds which are very jarring if you’re used to playing at smooth 250+fps on a 144hz monitor. This also occurred on the PTR version of the game. The only fix I’ve found is to restart the game which is obviously very annoying because I can’t do that during comp games. The reduce buffering on/off trick doesn’t solve the issue either.

My hardware is:

  • Ryzen 3600
  • MSI B450M Mortar
  • Nvidia GTX 980 Ti
  • Ballistix Sport LT DDR4 3000 MT/s CL15
  • Windows 10 Version 1903
