Question / Help Losing FPS during a transition

[eskimal]

I don't know if it's a configuration problem, of my PC, or of OBS, but every time I make a scene transition, the streaming FPS goes down to 20 or 30fps. (Not always, but after having showed some videos).

The transition I'm currently using is in .webm format, weighs about 8MB.

CFG:
- Intel i7 7700k
- GTX 1080
- 16GB RAM

I leave here the last log.

Thank you!
