This guide will show you how to add OptiFine to your Boosted FPS Forge modpack installation.
First make sure you have the correct version of Boosted FPS Forge - Boosted FPS [FORGE] Performance Mods - Minecraft Modpacks - CurseForge (use the CurseForge app and search for boosted fps)
Note: Below method is recommended for version 1.1.5 and onwards of the modpack.
Click into the modpack icon after it has installed (not play but the actual icon)
Click the 3 dots and select Profile Options
Tick the Allow content management option for the profile
Go to the Mods section and disable the following mods (Embeddium, Embeddium Extra, Oculus)
