OfftiFine
by moehreag
OfftiFine is a Utility mod for Ornithe on Minecraft 1.8.9 that limits what OptiFine can do over the network.
What it does
OfftiFine restricts the networking capabilities of OptiFine. It also fixes the FPS Limit setting resetting after a relaunch when OptiFine runs alongside OptiFabric on Ornithe. Only the client needs it, so servers and other players can join without installing anything. Its dependency Legacy OptiFabric must be present.
