GloriousEggroll – I mean, Ph42oN – brings the glorious FSR feature back to GE-Proton. Thanks to them for bringing this back; it will definitely come in handy for Linux desktop users.
Aside from that, Protonfixes were added to Hyperdimension Neptunia Re;Birth 1 and 2, and the usual set of software tools, including DXVK, VKD3D-Proton, and Proton-Wine, have been updated to the latest git. The Protonfix for Oceanhorn: Monster of Uncharted Seas has been removed since it is no longer needed, and Ph42oN also contributed a fix for fullscreen not working properly when FSR is disabled.
See the patch notes on GitHub.
