Onimusha: Way of the Sword on Steam Deck: rating and settings

Last verified 2026-09-21 by ReviewGamers Editorial

Onimusha: Way of the Sword launched on Steam on 3 September 2026, and Valve’s compatibility report rates it Playable on Steam Deck as of 15 September. This guide explains what each of Valve’s five test notes means for you and sets out the handheld settings Steam Deck HQ recommends from its own testing. None of the measurements below are ours.

Valve’s rating: Playable, with five notes

Playable sits between Verified and Unsupported. It means the game runs and is usable on the Deck, but Valve flagged at least one thing that falls short of its Verified bar. For Onimusha the report lists five results:

1. Interface text is not legible. This is the warning that keeps it from Verified. Expect small menu and subtitle text on the 7-inch screen.
2. The default controller configuration is fully functional. No community layout is needed.
3. Controller glyphs match the Deck. Button prompts show the right icons.
4. The default configuration is performant. Valve considers out-of-the-box settings acceptable on the Deck.
5. First-time setup requires an active internet connection. Do not expect to install it and start playing offline on a flight; get through the first launch at home.

The Steam page lists Windows 11 as the OS requirement, so on the Deck the game runs through Proton. It is priced at A$107.95 in Australia.

Why 30 fps is the sensible target

Capcom’s own minimum specification on Steam targets 30 fps on the Low preset at 1080p with upscaling, on a GTX 1660-class card. That floor is a desktop graphics card, so a locked 30 fps is the realistic handheld target rather than an arbitrary choice, and it is also where Steam Deck HQ landed. Capcom lists DLSS 4.5 and FSR 3.1 super resolution on PC; DLSS does not apply on the Deck’s AMD hardware.

Steam Deck HQ’s recommended settings

Steam Deck HQ published its review and settings on 31 August 2026. Its recommendation is deliberately hands-off:

• Frame limit: 30 fps
• Proton: default
• TDP limit: none
• Scaling filter: Linear
• Manual GPU clock: disabled
• Graphics preset: leave the defaults

Steam Deck HQ reports a mostly solid 30 fps with that setup, with stutter in the Eastern Kyoto hub area. Its power-draw readings were 13 to 14 watts in contained areas and up to 20 watts in the hub, with temperatures of 65 to 75 degrees Celsius, and it estimates 2.5 to 3 hours of battery life. The site also found that lowering settings produced little visual gain and made performance less stable, which is why it advises leaving the defaults alone.

Steam Deck HQ does not state which Deck model it used, so treat the battery estimate as a guide rather than a figure for your specific LCD or OLED unit.

System requirements and storage

The PC version requires 50 GB of storage on an SSD. Capcom’s official minimum specification calls for a GeForce GTX 1660 (6GB VRAM) or equivalent AMD Radeon RX 5500 XT, paired with an Intel Core i5-8400 or AMD Ryzen 3 3100, 16 GB of RAM, Windows 11 64-bit, and DirectX 12. This baseline targets 30 fps on the Low preset at 1080p with upscaling. The recommended tier steps the GPU to a GeForce RTX 2060 Super or Radeon RX 6600 and the CPU to an i5-10400 or Ryzen 5 3600, with the same RAM, OS and storage requirements. On the Steam Deck, a mobile APU with far less memory than even the minimum spec runs the game at the locked 30 fps target, which demonstrates why Capcom’s own floor—a desktop GTX 1660—is conservative for handheld playback.

Graphics modes and rendering settings

On PC, Onimusha offers two graphics modes: Prioritize Quality (targeting 30 fps at high resolution) and Prioritize Performance (targeting 60 fps at lower resolution). Ray Tracing can be toggled on and off, and frame-rate targets can be locked at three points or uncapped entirely. The game uses NVIDIA DLSS 4.5 and AMD FSR 3.1 for super-resolution scaling on compatible PC hardware; these technologies are not available on the Deck’s AMD GPU, which lacks DLSS support. On PC, ambient occlusion and complex shadow settings have the greatest impact on frame rate when adjusted, whilst most other settings—volumetric fog, shadow detail, and rendering distance—can be lowered from ultra to high or medium presets without noticeable visual loss. On the Steam Deck, however, Steam Deck HQ found that lowering settings from the defaults produced little visual gain and made performance less stable, which is why the default preset remains the pragmatic choice for handheld play.

Cloud saves and system features

Steam Deck and PC versions both support Steam Cloud saves, allowing play to resume across devices without manual file transfer.

Lock-on targeting mechanics

The in-game lock-on targeting system can exhibit inconsistent behaviour during combat. When an enemy moves or a lock-on target changes, attacks initiated under the previous lock may continue in the previous direction rather than following the new target. This is a known characteristic of the game’s combat system and not specific to the Deck.

How to apply it

1. Complete the first launch while connected to the internet, per Valve’s note.
2. Open the Deck’s performance overlay from the quick-access menu, set the frame limit to 30 and leave TDP and GPU clock controls off.
3. Under the game’s Properties > Compatibility, keep the default Proton selection unless Valve or Capcom advises otherwise.
4. In the game’s display options, set the scaling filter to Linear and otherwise leave the preset alone.
5. If you hit stutter in Eastern Kyoto, that matches Steam Deck HQ’s findings and is not a sign your settings are wrong.

What is not in this guide

Some sites claim 60 fps is reachable on the lowest preset with aggressive FSR settings, and mention a frame-generation option. Neither claim is verified against a named test, so neither is repeated here. Capcom’s own Steam post confirms more than 1 million copies sold worldwide on launch day, so more handheld testing is likely to appear; this guide will be updated if a named outlet publishes it.
