RushVR 0.4.0

Until Dawn: Rush of Blood in VR on a Windows PC, shown in a Quest 3 through Virtual Desktop.
Bring your own copy of the game (US release, CUSA03683, version 1.00); nothing of it is included.

What's new

• Shadows no longer flicker on and off. The emulator used to wipe the whole shadow picture every time the game cleared one tile of it, so which shadows survived changed from frame to frame. Now only that tile is cleared. (The flashlight's own shadows can still jump or show extra lines.)
• Large picture sizes (eye_width 2688 and 2880) no longer run the PC out of memory. The limit
  was the memory Windows can promise (RAM plus the page file). The emulator now frees pictures
  nothing has used for a while when that gets low. Set a bigger Windows page file for the largest
  sizes (see the README), and expect a lot of work for the graphics card.
• Sharpening has its own choice in the start-up window (Off to Maximum); Black corners has
  three tighter choices; the default field of view is now 105 (sharp, hardly any border).
• A MEMSTAT line every ten seconds in the log shows where the memory goes.

What you need

A Meta Quest 3 with Virtual Desktop, a PS5 DualSense connected to the PC, a Windows 10/11 PC with a
Vulkan 1.3 graphics card (an RTX 4080 laptop was used), and the game. Set Virtual Desktop's frame
rate to 120, then start Play Rush of Blood.bat. See the README in the zip.

Known problems

• The picture still looks pixelated or soft in places in the headset. Work continues.
• The flashlight's shadows can still jump around or show extra lines (other shadows no longer flicker).
• Now and then the game freezes for a second or more; the largest picture sizes can run slowly.
• Levels 5 and later are untested; a long session in level 2 and later still needs testing.
