What's new

First release.

World resolution below native with an FSR 1.0 upscale (EASU + RCAS) while the HUD, menus and text stay at native size. Purely spatial, so it cannot ghost. Default sharpening set from a measurement against a native reference frame: a bilinear upscale loses 40% of the picture's fine detail, FSR at this setting lands exactly on native.

Shader shadow map rebuilt every Nth frame instead of every frame, held together with the camera it was drawn from. Measured on the development pack: 70 / 82 / 93 fps at intervals 1 / 2 / 3. Default is 2.

Settings in Sodium's video options, in the mod list, and in config/vira.properties - all three write the same values and all apply while the game runs.

Includes a frame ledger: GPU time, render-thread time, 1% lows, stalls and where the world's CPU time goes, written to the log every five seconds. Off by default.
