I usually played with skype overlay, there was no problem at all, stable 160fps, no freezing, etc. but skype doesn’t exist anymore, and I tried with teams, at first it looked as a good option, until I tried to open the game, and I find my game was stuttering and caped at 30fps, searched for any solution and tried some but no solution really lasted, I’m searching for any suggestion beyond “quit the overlay” or “try another app” now I’m gonna detail the things that I tried and the results. Also you can try my solutions for steam overlay problems hoping any of 'em could help cause I see the gaijin response at this topic is “don’t use it -marked as solved-”. btw excuse my grammar I’m not a native english speaker
Reinstalling/updating graphics drivers: It worked, I could play just as always, 160fps with overlay an all, but only once for every reinstall, I started the game and goes well close game, start it again, and now I returned to the start, 30fps cap with stuttering
deactivating other overlays: stoped nvidia overlay and microsoft gamebar it give me like 2 or 3 extra fps at times + stuttering get worse somehow
deactivating hardware acceleration (from windows settings because teams quit lots of graphic config options on last update) and optimization for windowed games: I did it, and worked perfect, but again, only once, next time I started the game the 30fps cap returned.
deactivating g-sync: the stuttering got worse and fps went from 30 to 45fps randomly
reducing graphic configuration: nothing changes, its always capped at 30fps for some reason
Also, the overlay looks weird when the fps are caped the round corners of the overlay start flickering with a weird square black frame, when the promblem is temporally solved the border of the overlay looks normal.
