you need a way to detect fps?
i can help you in that case
EDIT: here it is:
local frames,fps,lastsec=0,0,0
addEventHandler("onClientRender",getRootElement(),function()
local frameticks=getTickCount()
frames=frames+1
if frameticks-1000>lastsec then
local prog=(frameticks-lastsec)
lastsec=frameticks
fps=frames/(prog/1000)
frames=fps*((prog-1000)/1000)
end
end)
