It is a known issue:
- FPS innaccurate for stage.frameRate
- Innaccurate fps to FlxG.stage.frameRate
- SDL_GetTicks Noticeably Imprecise
If I follow those threads correctly, migrating to SDL3 is a possible solution, if that’s the direction they choose. Version 3 was only officially released in January and I expect moving to it is no trivial task. There’s some discussion about that here.
