Waking a worker is a condition variable signal, a system call, and the main thread paid one per idle worker every 48 queued items. With Tekken 6's tiny draws (about 5 vertices each) the workers keep running dry, and those signals were about 10% of the main thread, which is what limits it there. Now no more threads are woken than tiles have work, and only the first is woken from the main thread; it wakes the rest. Co-Authored-By: Claude Opus 5.5 (1M context) <noreply@anthropic.com>
To get to 100% compatibility, we will need a software renderer as there are games out there that do tricks that can't really be faked in a sensible way. Useful for homebrew too that mix sw and accel rendering.
