Best Steam Deck Settings for Warhammer 40,000: Boltgun 2

The Boltgun 2 demo’s default 1280×800 resolution and 100% scale are the evidence-backed Steam Deck starting point; full-release performance remains untested.

For the pre-release demo, start with the default graphics settings at 1280×800 resolution and 100% resolution scale. Steam Deck HQ reported 60 FPS in many smaller fights and drops below 60 FPS—but above 30 FPS—in the largest fights. Those are observations from a demo build, not a guarantee for the full game.

Recommended starting settings

Use the demo’s default graphics settings, with resolution set to 1280×800 and resolution scale at 100%. Steam Deck HQ reported testing the demo at those values and said it reached 60 FPS in many smaller fights. In the largest fights, performance fell below 60 FPS while remaining above 30 FPS. These are one reviewer’s pre-release demo observations, not formal benchmark statistics or results promised for every Steam Deck.

What to try if heavy fights feel uneven

Large enemy encounters are the stress case identified in the cited demo testing. If frame-rate swings there distract from play, you can try a 40 FPS / 40 Hz cap through SteamOS and compare how it feels with the default uncapped behavior. This is an experiment for your device, not a setting established as optimal by the Boltgun 2 test. Check frame pacing and battery use yourself; comparative results for different caps and Deck models have not been established.

What the demo results do—and do not—tell you

The figures above come from Steam Deck HQ’s hands-on pre-release demo preview: Steam Deck HQ’s Boltgun 2 demo performance report. They offer a useful starting point, but do not establish full-game performance, worst-case frame rate, or battery life. A separate Deck Wizard video description names a Steam Deck OLED and SteamOS 3.8.5 for a May 21, 2026 demo test, but does not state the graphics values tested; it cannot confirm a particular preset.

Release status and compatibility context

As of October 7, 2026, the Steam listing scheduled the PC release for October 14, 2026, with a public demo available and the full game not yet available for purchase on Steam. The listing describes a single-player first-person shooter featuring Malum Caedo and Nyra Veyrath, with a branching campaign. See the Steam store listing for the current release details.

Steam’s minimum and recommended specifications are Windows PC requirements, not a Steam Deck compatibility rating. The minimum lists an Intel Core i5-8600K or AMD Ryzen 5 2600, 8 GB RAM, a GeForce GTX 980, Radeon R9 Fury, or Arc A580, and 13 GB storage. Recommended specifications list an Intel Core i7-10700 or AMD Ryzen 7 2700X, 16 GB RAM, a GeForce RTX 2070 Super or Radeon RX 5700 XT, and 13 GB storage. Those desktop requirements do not substitute for testing the game on a Deck.

What to check when the full game is available

The October 14, 2026 release date is scheduled, not evidence that the launch build has been tested on Steam Deck. After release, the useful checks are frame pacing in a representative heavy fight, clarity at 1280×800, and battery runtime on your own model. Until those results are available, the demo defaults are the best evidence-backed starting point—not a definitive full-game preset.

The developer also describes returning gameplay accessibility options—Invulnerability, Infinite Ammo, and Unlock all weapons—plus new Undying Mode. These are gameplay options, not performance settings for Steam Deck.
