Performance features such as optifine can be added, shader support and texture pack support can be added, or a combined version with optifine can be released.

OptiFine is a closed source mod, which means it is up to its author to release and implement by PR into Forge the way by which they claim to improve performance.

Note that OptiFine is known to cause a large deal of compatibility issues due to its unusual method of modifying the game, to the point that one of our first recommendations when troubleshooting is to remove OptiFine and similar 'performance-enhancing' mods.

We try to improve the performance of the base game in careful increments, taking care to retain vanilla behavior. (Many performance enhancement mods usually limit or downgrade certain vanilla systems, which lead to behavior differing from vanilla Minecraft.) Most of the time, Minecraft itself improves performance through its various updates (though most don't realize it, because of the focus on feature additions).

Shaders are somewhat of a difficult topic to tackle, because the shaderpack format used by OptiFine is (as I understand it) very specific to OptiFine. Mods exist (both on Forge and on other modloaders) which provide shaderpack support, albeit not to the same specification as OptiFine, and thus needing shaderpacks to support those (usually open-source) shaderpack formats through rewriting.

Because of OptiFine's status as a closed source mod with a restrictive license, we are legally unable to redistribute OptiFine. (This is the same reason why modpacks also don't ship OptiFine.) In addition, we are unwilling to add a mod like OptiFine, as we prefer (genuine, non-vanilla-breaking) performance enhancements to be merged into Forge proper, rather than redistributing a mod not under our control/supervision.

TL;DR: Nope.

Maybe this will work Link to illegaly distributed decompiled Optifine removed not sure of authenticity
