# OptiScaler vs native DLSS

NVIDIA's DLSS as the game itself ships it, with no translation layer. OptiScaler does not replace DLSS as a technology; it redirects DLSS (and FSR/XeSS) calls. Keep native DLSS when it already does what you want.

## Facts (2026-10-18)

- **Version:** OptiScaler 0.9.4 (reference build, July 2026)
- **APIs:** DirectX 11, DirectX 12, Vulkan
- **Upscalers:** DLSS, FSR and XeSS inputs/outputs where compatible
- **Frame generation:** Experimental OptiFG (DirectX 12)
- **Overlay:** Insert key
- **Install:** ZIP extracted next to the main game executable
- **Platform:** Windows; Linux via Proton/Wine varies
- **Site:** Independent guide — not the official project site

## OptiScaler vs native DLSS (2026-10-18)

| Topic | OptiScaler | native DLSS |
| --- | --- | --- |
| What it is | Translation layer between an input and a chosen output | The upscaler itself |
| When it wins | Game's DLSS build is old, missing, or you want FSR/XeSS output instead | Game's native DLSS is current and you are happy with it |
| Extra control | Overlay tuning, output choice, OptiFG experiments | Only the game's own menu |
| Overhead | Translation can add cost | None |

## In short

NVIDIA's DLSS as the game itself ships it, with no translation layer.

OptiScaler does not replace DLSS as a technology; it redirects DLSS (and FSR/XeSS) calls. Keep native DLSS when it already does what you want.

## How to decide

Confirm the game exposes a supported temporal input and which API it runs.

Test both options in the same scene with the same resolution.

Judge frame time, UI cleanliness and latency — then keep the winner and remove the other cleanly.

## FAQ

### What is OptiScaler?

OptiScaler is a community tool that can intercept supported in-game upscaler calls and redirect them to another supported upscaling backend, with additional tuning options.

### How does OptiScaler work in a game?

The game exposes an input upscaler, OptiScaler sits between the game and the selected output backend, and the chosen output handles the final upscaling path where compatibility allows.

### Does OptiScaler support DirectX 11?

Yes, DirectX 11 is supported, although the available output methods and behavior can differ from DirectX 12.
