Description

If you limit FPS on nvidia or ingame settings, it affects loading times of KSP.
Same happens if you put VSYNC ON.
I got game start with lot of mods at 1minute 5 seconds without FPS limits and VSYNC off.
If i limit my FPS to my monitor i have to wait game couple minutes.

I wanted to limit fps so my gpu doesn't warm too much.

I can confirm this issue, I posted about it in length here: https://forum.kerbalspaceprogram.com/index.php?/topic/196525-ksps-load-times-are-still-limited-by-fps-improve-your-load-times-d/

Basically, it appears that coroutines run on Update so if any resource load takes less than a frame length in time then the rest of the time in that frame will be wasted until the next new frame. This is the cause of the wasted/additional loading time.

Depending on frame rate limiting, at 30fps I was getting over 3x longer load times when compared to an unlimited frame rate which is quite shocking.

I have a video showing this here: https://www.youtube.com/watch?v=4rb7QubxGO8&feature=emb_title
