One update quietly un-breaks a stack of Linux games on Steam Deck, the other is a publisher racing to fix a fighting game's launch-week PC problems. Both are the kind of fast, unglamorous fix that matters more to day-to-day play than any headline spec.
Proton Experimental Clears a Multi-Game Backlog
Valve's August 7 Proton Experimental update resolves a handful of regressions that had been actively breaking games rather than just running them poorly, per GamingOnLinux's changelog coverage. Far Cry 5 stops throwing a false "old driver" warning on AMD GPUs and gets working HDR on OLED Steam Deck units. Nightingale's Steam authentication failure is fixed, which had been blocking the game from launching at all for affected users. Lords of the Fallen returns to playable after a regression introduced in Proton 11, and seven Command & Conquer titles (Generals, Zero Hour, Kane's Wrath, Tiberium Wars, Renegade, and Red Alert 3) can detect Steam Workshop custom levels again. Steam Deck HQ's report on the same update adds a Forza Horizon 4 memory-leak fix specific to launching under KDE Wayland.
None of this is new functionality; it is Valve paying down a backlog of things that stopped working, which is the less visible but more consequential half of Proton maintenance. Anyone hitting one of these specific bugs should just need the Experimental branch to update, since none of the fixes require an opt-in flag.
Marvel Tokon's PC Patch Cuts the Stutter, Not All of It
Arc System Works' Marvel Tokon: Fighting Souls launched August 6 for PS5 and PC, and the PC build drew immediate criticism for stuttering and inconsistent frame rates severe enough that fighting-game creator Maximilian Dood uninstalled it, according to PC Gamer's coverage of the patch response. Four days later, a 10GB patch went after CPU-side causes rather than anything GPU or driver related: reduced CPU load during startup, removed unnecessary audio processing during matches, and fixed a bug where the game was continuously polling for available audio inputs and dropping frames as a result. It also fixed frame-rate drops tied to specific resolution choices and improved automatic graphics-quality detection.
Reception is mixed rather than resolved. Push Square's rundown of player reports describes many players getting smoother frame rates and better online matches, alongside others who say the game feels largely unchanged, so the patch is best read as a real improvement for a launch-week problem rather than a full fix. Steam reviews for the PC version have not recovered to match the console reception, which tracks with a stutter problem that a CPU-side patch improves but does not fully resolve for every system.
