Question / Help OBS preview fps drops from full 60 to 40 to 30 fps when in game is fine

[Krikey]

I'm not sure if this is a bug or not but it's mostly been a problem in the previous versions of OBS Studio. I've noticed when even testing out 60 fps preview in obs studio then alt tabbing back into the game the preview drops to 40 to then almost 30 fps when in game is 60+ with NO drop at all. AND with multiple games tested the same thing has happened as well. Also when I'm not testing 60 fps and streaming at 30 fps sometimes it dips to almost 20 with the same issue but when alt tabbing out of the game goes back to smooth 30 or 60 fps on OBS :/ I'm hoping this will get fixed in 0.16.6 but if this helps here's my computer specs!

CPU : AMD FX 8350 Black Edition
GPU: Nvidia GTX 750ti 2GB
RAM : 16GB RAM DDR3
OS : Windows 10 Pro 64-bit

Also here's a log file from when I was just testing the preview as well but hopefully I'm not the only one having this annoying issue and hope this gets fixed as soon as possible just trying to help out!

You need to submit a log that had a recording attempt, not a log that just shows the preview. That said the GTX 750 Ti is too easy to overload the GPU to cause OBS to stutter regardless of OBS settings. You'll have to reduce the GPU load by reducing the game settings and capping the framerate.
