In Async (UberShaders), where ubershaders draw only until the specialized pipeline is built, their pipelines are keyed sized for 8 texgens, and the pixel shader reads the draw's count from XF's, kept in the pixel constants' padding (the block and savestates keep their size). 3 are built before the game starts where there were 27. Over the corpus, shaders made fall from 134 to 102, their words from 737739 to 274571, pipelines from 182 to 158, and loading from about 1.03 s to 0.22 s on lavapipe, with the same pictures; ubershaders sized so drew every frame the same too. Synchronous (UberShaders) keeps them sized for the draw's texgens.
