For where there's no vertex JIT (iOS), as they're a few percent slower
than the JIT's but four to eleven times faster than the steps. The
formats carry most of the vertices of ATV Offroad Fury: Blazin' Trails,
Wipeout Pure and Killzone: Liberation, and a lot of Gods Eater Burst's.
They convert like the steps (PrescaleUV moves to the header for that),
and the vertex decoder test now also compares each format's decoder
without the JIT against the steps.
Without the vertex JIT, 10 emulated seconds on an M1, instructions:
ATV -9.9%, Wipeout -6.0%, Killzone -5.4%, Gods Eater -2.2%.
