this is why I'm always mad that the lerp/deltatime system became the industry standard instead of just having an absolute value per frame- https://twitter.com/adampi/status/1310225180719853568

this would go on to cause a lot of problems in itself, however. I use fixed values every frame and it's slightly less buggy HOWEVER pretty much every physics system in existence works on deltatime, and you know what that means

fixed values are unadjustable meaning you can't ever make the game run at a different framerate to the one you hardcoded into it. this is why so many old games can't be re-released with a higher framerate. also if one object's scripts run on deltatime and another is fixed that-

-means they will move at different speeds depending on how fast your computer runs! nightmare!
