Onimusha DLSS 5 Mod Tested on RTX 4090 — 33 to 43 FPS at 4K

A DLSS 5 mod for Onimusha: Way of the Sword lifts an RTX 4090 from 33 FPS to 43 FPS at 4K Quality, and hits 60 FPS at 1440p Quality.

RTX 4090, 4K, and a mod that buys ten frames.

A player-built DLSS 5 mod for Onimusha: Way of the Sword has been put through its paces on an RTX 4090, and the results show both how far the mod stretches and how demanding the game's 4K path is on native hardware.

The Measurements

Test conditions: 4K resolution, DLAA anti-aliasing, settings below maximum. In that configuration the game averaged 33 FPS natively. With the DLSS 5 mod in Quality mode, the average climbed to 43 FPS at 4K. Dropping to 1440p with DLSS 5 Quality pushed the average to 60 FPS — a genuinely smooth target on this card.

Context for Your Own Setup

The stock game officially supports DLSS 4.0 and FSR 3.1 upscaling, and Capcom's own platform performance targets promise 60 FPS console modes at dynamic resolutions — so a 4090 needing upscaling for comfortable 4K says more about the native 4K load than about the card. If you are chasing 4K/60, the practical ladder is: DLSS/FSR Quality first, mod second, settings trim last.

If your rig is more modest, the mod's 1440p result is the number to remember: mid-high cards can reach 60 FPS where native rendering cannot.
