Well, I have a really good pc, RTX 2080 Super, Ryzen 5 3600x (4.3Ghz oc), 24GB Ram 3200Mhz (corsair dominator) and my fps usually is around 300, but when in teamfight, it drops to around 210. On some specific maps, like gibraltar , it doesnt even reach 200, and those 3 dots appear next to the fps. The thing is, the CPU and GPU are always under 50% of usage, and since I have a 240hz, I would like to get 240 fps or more all the time. Things that I tried:
Disabled high precision event timer.
Turned AMD cool n quiet off
Updated drivers
Put high priority on OW in task manager
Turned SMT off but turned on again
Tried changing some GameDVR configuration.
Some of them helped, but not enough and sometimes Im still getting those damn 3 dots. The temperature is always between 40 and 60 degrees celsius too
