Question / Help Huge FPS loss when Recording gameplay

[AussieDucker]

Hi, I've been using OBS for a little while now and have had no dramas with framerate loss until I started recording Tennis Elbow 2013. I can play the game on 60 fps without issue until I start recording with OBS when it drops to just 18 fps.

I'm wondering whether or not the game is poorly optimized (which wouldn't surprise me) but can anyone have a look at the most recent log to see if I'm missing something obvious? I recently changed my encoding from x264 to NVENC to see if that made a difference but it did nothing.

Cheers.

Urgh, I feel so stupid but I've fixed the problem.

The game is in windowed mode but I was using Game Capture. As soon as a I changed to Window Capture - bingo!

As you were.
