Proton Experimental Update Fixes Crashes and Regressions in Several Games
The October 2 release addresses a crash in Terminator: Dark Fate - Defiance, a memory leak in Plan B: Terraform, and two Proton 11 regressions.
Proton Experimental received an update on October 2 that brings further Windows game compatibility improvements to SteamOS and Linux, according to gamingonlinux.com. The release targets a handful of specific titles rather than introducing broad new features.
The update fixes a crash in Terminator: Dark Fate - Defiance and a memory leak in Plan B: Terraform. It also resolves a rendering issue in Sword of the Stars II: Enhanced Edition.
Regression and startup fixes
Two Proton 11 regressions are addressed: Lara Croft and the Temple of Osiris no longer suffers controller stutter, and Locoland plays videos properly again. In addition, the update fixes camera rotation stutter in the experimental branch with the STEEL GULLET Demo, and Blue Effect VR now starts on some CPUs where it previously failed.
Valve recently enabled the FEX code cache in Proton Experimental (ARM) to improve frame timings, and another Proton Experimental update shipped late last month with more general game fixes. The most recent stable version of Proton is Proton 11.0-2.
