KNOWN ISSUES

In addition to the issues identified previously, we’re working on a number of high-priority issues:

Some players are experiencing startup crashes. Patch 1.01 fixes a few, but not all, of these crashes.
Some players are experiencing GPU-related hangs during gameplay. The improved diagnostic data collection added in Patch 1.01 is aimed at making it easier to track these down.
Some players are experiencing graphical settings issues, such as Anisotropic Filtering not working, 4K not displaying correctly, or HDR not working correctly.
Some players are experiencing performance issues on specific GPUs or hardware combinations.
We're aware of and continue to investigate all issues in this list on Reddit as well. Thank you to u/EvilMonkeySlayer for compiling this for us.
