Proton 8.0-4 Released With a Long List of Fixes


There’s a new Proton version in town, and it’s been a while since there was one. The previous one was in July 2023. This version comes with a long list of fixes and improvements, as you can see from the release notes, but we have organized it here in a more readable way with more categories. The good thing is that it fixes not just new games, but also more ancient ones like Chaos Code - New Sign of Catastrophe -, a fighting game from Arc Systems Released on Steam in 2017.

Enabled nvapi for the more titles

Enabling NVAPI (NVIDIA Application Programming Interface) for certain titles allows for more efficient communication between those games and NVIDIA graphics drivers, potentially improving performance, compatibility, and overall gaming experience. This can result in better optimized gameplay, reduced input latency, and enhanced graphics rendering, among other benefits.
