Huge FPS Improver (Not Mine)

Note: Hugely increases FPS. Recommended to use for autofarming. Graphics will look very bad after execution.
Script:
for _,v in pairs(workspace:GetDescendants()) do
if v.ClassName == "Part"
or v.ClassName == "SpawnLocation"
or v.ClassName == "WedgePart"
or v.ClassName == "Terrain"
or v.ClassName == "MeshPart" then
v.BrickColor = BrickColor.new(155, 155, 155)
v.Material = "Plastic"
end
end

for _,v in pairs(workspace:GetDescendants()) do
if v.ClassName == "Decal"
or v.ClassName == "Texture" then
v:Destroy()
end
endd
