It seems that every time a new YouTube video is played, in a Tribe House, that Transformice's FPS really hit an all time low. The issue resolves itself if /np or a new video is started usually. I thought this could be due to the standalone I am using but talking to others it seems that their FPS is also experiencing similair woes and they've reported different standalone usages so I am thinking it could be a bug related to TFM instead. Has anyone else experienced this sort of thing?

Yeah i experienced this too with baffler standalone, after another map is put, i lag like hell :c

What you describe suggests your computer cannot handle running both Youtube and your client simultaneously, but unless you are playing with something extremely outdated I doubt that your computer can't handle that. Were you running anything else in the background while playing? Have you actually tried using a different standalone?

I just tried Tigrounette's official standalone, played a video in my Tribe House, exited into a solitary room and experienced FPS lag. My laptop is adequate enough processing wise so it is not that. The only things I have open currently are Google Chrome and Tigrounette's standalone.

This happens to me occasionally but since my computer's CPU is like, Celeron, I've got adapted to this heh.
