This update is about optimization and consequent extending of Visibility distance and smoother FPS for all quality settings.
Also new quality level "High" was added to play with "Ultra" image but w/o heavy soft shadows.
You can extend visibility (Menu / Advanced / Visibility) to the maximum almost w/o any performance impact.
Checked on hardware from AMD FirePro 5130, Vega7 to RTX 2060.
Note: 1st run of Demo will check performance and drop all settings to low if FPS is lower than 30. But you can improve settings further via Menu (see Quality level) and Menu / Advanved (more granular settings).
