Pyra's lying, v3 is opti bun.
V1 had sps already, V2 has a new bun added to the group of buns, and now V3 is an optimized version of the bun.
Also pyra doesn't have access to V3 anyway they got banned already ._.
(I'm friends with the creator and have access to the logs personally idc if it get leaked or ripped but if you gonna say stuff at least be truthful and accurate )
