Users were reporting fullscreen crashes and freezes, which upon investigation looks related to Windows 10 display scaling. This update should address the crashes, but depending on your scaling settings, you may still notice some odd behavior -- I recommend disabling the Windows 10 "fix blurry apps" option if you have scaling enabled and want to use this game fullscreen.
OpenVR has been updated to v1.14.15.
Testing has begun (albeit very limited) on 5089's sequel on Discord @ https://discord.gg/4quab2d
v1.5.8 fixes a VR texture format issue, which should make the VR display brighter.
v1.5.9 should fix VR issues on AMD hardware.
v1.5.10 fixes a minor UI issue with lists, adds an error message if your drivers are out of date and fixes some extremely rare crashes.
v1.5.11 improves behavior when Windows 10 scaling is enabled and "fix blurry apps" is also enabled, although this combination is still problematic and error messages have been improved.
