    Question / Help OBS Drops Frames on NVENC Encoder, Shadowplay Does Not

    Hi! I know there's been questions about this before but I can't for the life of me find a fix. NVIDIA Shadowplay is great, and records my games (Star Wars Battlefront 2015 is being used as a baseline for these tests) at 1080p around 60FPS. Of course, the supported games list isn't too long and...
