Should I use Delta Time?
I'm rewriting my base code. In my previous love2d projects i have used dt because everyone says you should, but I'm starting to question it's usefulness. I cap all of my games to 60fps because that's the max refresh rate on most monitors and you can't tell me i need more than that for simple 2d games. Unless you're using the latest toaster technology, you will never be dipping below 60fps with my stuff. So my question is, if I'm running on a fixed timestep anyway, what is the usefulness of multiplying by dt? I always hear that it should be used, but I've yet to see a compelling argument. I'm curious. Why do you or do you not use dt?
Re: Should I use Delta Time?
As someone with a 144hz monitor, I'd appreciate the game not to be capped at 60 FPS
However, if you're certain your game will run 60fps at all times, theres no point in using delta time (Though I'd still suggest you learn how to work with it.)

It's not only toasters that may have issues; consider one of your users having a powerhouse of a rig, and for one reason or other, either disables vsync because they force that setting, or that the gpu drivers are shit, and it's buggy so it won't use it: Now your game runs at light speed for them.
Using dt isn't hard; if you want to have determinism in your code, feel free to use an accumulator and a fixed timestep USING dt.

If the game runs slowly (~30 FPS instead of 60), because it's loading something for example, the game will slow down if you don't use dt.
