Yes, I know Forge for the version 1.18.1 is still in the beta phase but I still wanted to report the issue I am facing. It seems like the average frame rate is extremely low while using this version. In normal/Optifine 1.18.1, my pc achieves about 400-500fps without shaders/120-160 with heavy shaders while it can only achieve about 40-70 fps with and without shaders when running Forge 1.18.1.
Again, I know that it’s still a beta version, but I still wanted to point out this issue.
