Question / Help OBS lags with PUBG, but nothing else


New Member
So in the 3 weeks, when i play Pubg it lags my obs making it impossible to stream the game. The strange thing is every other game is fine and iv never had this problem before with Pubg.. I have reinstalled obs to latest version 21.1.2. I have switched servers and nothing helps. I have installed pub and obs numerous times also.
Ill provide some spec info, any help would be appreciated : )
