Highlighting some of the key changes Collabora worked on with Valve to improve the system update tooling on SteamOS.
I'm late to the comment board, but I had to say something. I was amazed when one day my broken Balders' Gate III P22 install suddenly not only worked, but worked with Vulkan. Until now, I figured it was an improvement to the Proton-GE or Experimental that came down around that time. Anyway, when I loaded my game (in the underdark) on my OLED, I was shocked at the improvement.
Not only was the framerate closer to 40+ vs 28-30, but it was vibrant. The resolution appeared to be better, too. It was gratifying to see it looked better than on my ancient Lenovo gaming laptop (circa 2016), which, to my surprise, handled it quite well considering the age of the NVidia card.
