Those results are pretty spectacular, and they show that the strategy of reducing I/O load during gameplay has paid off.
The quiet (-xyq) benchmark numbers are consistently 22% higher FPS than for the last version.
The -xy numbers are even better: +26% (8MHz), +49%(16MHz), +30%(16MHz + cache). Are you sure about the 16MHz numbers?
Anyway, looks like a Mega STe is becoming a viable option for playing, at least with music turned off. When 0.3.0 was launched, the Falcon had worse numbers than your Mega STe has now.
Thank you, this made my day!
