Changed
DXVK async shader compilation is now off by default, and existing bottles are switched off once. It had been on for every game since 0.3.0.
Despite the name, it doesn't compile in the background and draw later. When a shader isn't ready it skips the draw and shows the frame without that geometry. DXVK's own developers decline to ship it, and the engine's built-in default is off, so Highball was actively turning it on rather than leaving it alone. It was never measured to help on Apple silicon, and when finally measured it made no difference (−0.1%).
The toggle is still in bottle settings if you want it, and it's now labelled to say what it actually does.
Fixed
Bug reports attached the wrong log (#21). Report a Problem could pick a bottle's startup log, which ends before your game runs and can't show what went wrong. It now skips those whenever a real log exists.
Bottle settings recorded sync markers without rewriting the whole snapshot, so repeated changes stay consistent.
