Low Detail - LlemonDuck/runelite GitHub Wiki
Low Detail Configuration
(Default Off) The game will run in low detail, reducing memory usage. When enabled, ground decorations (like pebbles and grass), and some textures are turned off.
Warning:
Please note, Low Detail mode can cause some textures to not render or disappear (e.g. Seer's Rooftop Agility). Turning off this plugin and restarting the client will fix this.
