Europe, UK, Japan, Asia, and the editions with The Old Hunters). No game files are included.
Linux x86-64 and a Vulkan 1.3 GPU.

None.

Improved

  • Video memory: the copies of the game's memory kept in VRAM are compacted in the default settings too, giving back the VRAM they no longer use. From SrShadowy's fork.

Fixed

  • Frame rate drops that lasted until a reload in some places, mostly on NVIDIA cards (#42). When VRAM was full, a copy of the game's memory could land in system memory and stay there, and the GPU read it over the bus. On cards with more than 4 GB those copies now stay in VRAM, and one that doesn't fit is made again later. BB_MIRROR_VRAM_ONLY=0 (under Advanced > Developer > Extra variables) brings back the old behaviour.

Upgrading

  • From 0.70-linux.3: the launcher's About page installs this one. Your saves and settings stay as they are.
  • If you added BB_MIRROR_VRAM_ONLY=1 for #42, you can remove it: it is the default now on cards with more than 4 GB.

Known issues

  • Stretched shapes can appear for a moment in random places, and a texture can look rainbow-coloured in Yahar'Gul; a reload clears them (#25). Under investigation.
  • Amygdala's lasers could look black (#19).
  • A strong blur can stay after a load with motion blur on (#1). Turning motion blur off avoids it.
  • A crash at guest offset 0x263b8e7 can still happen on the Steam Deck (#27).
  • Local co-op runs a whole game per player: on a mid-range GPU at 1440p, two players get about 30 to 40 FPS each.
  • Above 120 FPS the game's movement can break; the launcher warns about it.
  • Only the 1.09 executable is supported; other versions start and then crash.
