Accessing a players Graphics Quality?

Well it seems since the global settings() table is protected and can only be accessed by roblox corescripts and game:GetService'RenderSettings' isn't working, there is no way to access the quality level that I know of, sorry for getting your hopes up.

--[[
local render = settings().Rendering
local qualitylevel = render.QualityLevel -- Quality level of the player


 For some reason unbeknownst to me, the quality levels range from Enum.QualityLevel01 -Enum.QualityLevel21, even when you can only change the quality level bar to levels 01,04,06,08,10,12,14,16,18, and 21 in the default roblox settings tab


if qualitylevel == Enum.QualityLevel.Level21 then -- Level 10
print("Highest quality level")
elseif qualitylevel == Enum.QualityLevel.Level01 then-- Level 1
print("Lowest quality level")
end


-- The lowest value is Enum.QualityLevel.Level01 (AKA 1)
-- The highest value is Enum.QualityLevel.Level21 (AKA 10)

I just played around with RenderSettings, and the error you receive happens even when just calling RenderSettings like this:

renset = game:GetService("RenderSettings")

I tried looking around the Wiki for more, but there isn't much on the Wiki about RenderSettings. I don't think it resides in each player though. So I don't think you can be like

game.Players.PlayerName.QualityLevel

or anything like that.

I'm sorry I couldn't offer more help. I tried to get the QualityLevel of anything in-game, and all it says is "QualityLevel is not a valid member of ..."
