Meh, I'll wait for OBS devs to fix this in a new update. Till then, I'm not going to record R6S (because the video will be very laggy). By the way, I've found that if you're using the new Nvenc Encoder and you don't have the best GPU (for example: me, GTX 1050Ti), you should disable Look Ahead option and Psycho Tuning thing option + decrease the preset from Max Quality to Quality. These things have broke my frames while recording. Even with only Max Quality and those options turned off, my last video had 7% stalled frames. But after changing the preset to Quality, my last video had 0% stalled frames. But yeah, I can see how OBS is still broken.
