Bug #24388
Very low FPS after entering a scene sometimes
0%
Description
I have this weird issue where, sometimes, when I enter a scene, the FPS appears to drop to almost nothing. The debug window says ~30 FPS, but it feels more like 1 or 2 FPS. Perhaps this is because the UI interaction is also really sluggish. Then, when exiting the scene and immediately reentering it, everything will be fine, with FPS being 60 and the UI being responsive.
I've noted that when this happens, KSP will use only 10% CPU, despite more than 90% being available. When exiting and reentering the scene, CPU usage shoots back up to its usual 50%-100%.
So far I've had this happen in the main menu scene, and the VAB scene. Exiting these scenes (but not exiting the game) and then going back fixed things.
The debug window show no log-spam.
Note that my hardware specifications will register as "low", but I've had no such issues in KSP before 1.8.1 (note, the last version I played before 1.8.1 was 1.7.2). In fact, when the issue does not happen, performance is significantly better than in 1.7.2 (from 15 FPS to 60 FPS).

This log is of a session where it happened every time I entered the editor except for the first time. The first time I entered the editor, it only happened when the part highlighter was active.
