Pretty much every performance modpack is for fabric But some pople still use Forge and high FPS can be obtained on Forge too
This is a very barebones modpack with no bloat. If you want to add some exta mods you can. Some optional mods that I reccomend are Oculus and JEI
I highly advise against using Forge on versions after 1.20 as mods are dropping support for it left and right. If you really want to use it though, install Bedium
Fullbright SP is included and enabled*
