Revenant Survivors action roguelite targets Steam Deck via Proton

Mongma Studio is preparing to launch its dark fantasy survivors-like roguelite, Revenant Survivors, into Steam Early Access. While the game is a Windows title, developer testing indicates it is playable on Linux-based handhelds using the Proton compatibility layer.

Initial performance testing on a Steam Deck LCD running SteamOS 3.8.28 and Proton 11.0-2 shows the game maintains a stable 60 FPS during standard gameplay. However, performance dips occur during high-density combat encounters, with frame rates dropping to between 38 and 49 FPS.

Steam Deck performance and Proton testing

• Compatibility Layer: The Windows build (version 0.2.9) was tested using Proton 11.0-2 on SteamOS 3.8.28.
• Hardware Configuration: Testing was conducted on a 512 GB Steam Deck LCD at a native resolution of 1280 × 800 and a 60 Hz refresh rate.
• Frame Rate Stability: Standard combat maintains a 60 FPS cap, but crowded enemy waves cause drops to 38–49 FPS, with brief dips below 30 FPS lasting approximately three seconds within a five-minute sample.
• Stability Metrics: No system crashes or freezes were reported during the 304-second test period.

Why it matters

This development highlights the ongoing importance of Proton for bringing Windows-only roguelites to the Steam Deck ecosystem. While the game is not yet 'Verified,' the successful execution of the Windows build suggests that developers can achieve playable results on SteamOS even in the Early Access phase.
