granite prism
I recently played with the game commands and discovered "mat_drawwater 0" which removes water entirely and thus obviously increased my FPS as well. I was also aware of commands like r_rootlod or mat_picmip having a higher but sv_cheats restricted values.
are there any other commands with similar properties, like what would mastercomfig "very low" be like if certain commands were not sv_cheats restricted?

you could have a look through tf2's cvar list and see if there's anything that interests you: https://docs.comfig.app/latest/tf2/cvarlist_win/
look through the ones labeled as "Cheat" or something

obvious one would be r_drawothermodels 0!
