Usually PS1 games don’t run at 60 fps. Almost every PS1 game runs between 15 and 30 fps and Roblox is capped at 60.
Here’s a script you can add to cap the fps to what ever you want! If you do not like this and would rather leave it at 60 than that’s fine i just thought that some people would like this, i know i do.
local script in starter player scripts.
local RunService = game:GetService("RunService")
local MaxFPS = 19
while true do
local t0 = tick()
RunService.Heartbeat:Wait()
repeat until (t0 + 1/MaxFPS) < tick()
end
