hey guys I'm not sure if this is a bug but it's extremely annoying and should be changed if it's intentional;

When I'm playing I normally get 60 FPS but if I want to watch a video or something on the other screen sometimes I will only get 30 fps and for some reason when the game slows down to 30 FPS it seems to lower the timescale by about half at the same time as if I had used game.speed = 0.5.

This can easily be reproduced with Bandicam or DXTory by limiting the framerate.

Hello,
not sure what the reason is, the rendering parts waits for vertical sync, it can be affected by that maybe.

You can try to select Options->other->Low fps, this way, the game runs on 30fps, but there are two logic updates per one render update, so the game speed is preserved.

Just to make that thread complete: What should I do to set the timescale to 50 Hz?
In my opinion I need to set ??

Should be so but... Why?

Let the game run with 50 Hz update rate... So in a video with 25 frames/sec there is no stutter, when recorded with 50 Hz from your grafix card, which was running on a 50 Hz screen.
