OBS lags when I record Starcraft 2. The game doesn't lose fps, only OBS.
I record other games with OBS and I have no problems, but with Starcraft 2, OBS lags.
I noticed this issue after Windows 10 got an update on 13th of May 2018.
System Specs:
OS: Win 10
Video Card: TitanX Pascal
Processor: i7 7700k
RAM: 32GB
2GB SSD
6GB SSHDD
What could be the cause of this problem?
ps: before 13 May 2018 I used to record SC2 with the same settings and I had no problem.
pps: when I opened OBS after 13 of May 2018, my Audio Track and Microphone where reset, I had to specify them again.
