DLSS 5 Swapper

Install and manage DLSS 5 Neural Rendering for compatible games and emulators.

Windows Installer · Portable · Checksums

Features

• Easy installation: native DLSS games, or compatible non-DLSS games through DLSS5-Feeder.
• Your library: Steam, Epic, GOG, modern Xbox Game Pass folders, and manually added games/emulators.
• Search and filters: combine title, graphics API, DLSS status/version and add-ons; click counters to filter.
• Flexible layout: group by store or show everything in one list, with game artwork and light/dark themes.
• Controlled scanning: full-drive scanning is off by default. Added folders still scan normally; enable all-drive discovery or remove scan folders in Settings.
• Right-click shortcuts: open/copy folder, rescan, change cover, restore originals or hide a game.
• Backups and History: restore original files, keep installation records, and copy History/activity/install logs.
• In-game overlay: press F8 to open the app's own panel over the running game and move the real DLSS Neural Rendering sliders while you play. Supports the DLSS5-Feeder and RenoDX v4.7 routes only.
• Rendering API override: optional, per game, with Automatic as the default; detection is never overwritten.
• Custom add-ons: the Add-ons page remains available alongside the integrated installation routes.

New in 2.2.3

Six faults reported by people using 2.2.2, each fixed at the cause.

Installs that were refused for no good reason

• An older card can now try OptiScaler. OptiScaler itself has always run on RTX 40; what needs Blackwell is the neural model file. Upstream 0.2.0 says plainly that older architectures work with a modded nvngx_dlssnr.dll, so the card joins the driver as something said rather than enforced - and a modded model already in the game folder is kept, never overwritten.
• A failed process check no longer refuses the install. Reading the running process list can fail on its own - PowerShell restricted by policy, a cold WMI service - and that failure was being reported as "close the game first" to people whose game was already closed.
• A saved backend profile no longer makes a game uninstallable. ReShade lets a preset be named anything, and mod packs ship them as .txt: the app saved those and then refused to read them back, so the game could not be installed again at all until the profile was deleted by hand. This is the "Invalid backend profile" report.

Getting the neural pass to actually run

• A game's own outdated shader compiler is retired during the install. Spider-Man Remastered ships D3DCompiler_47.dll 6.3.9600 from 2013 beside its executable, Windows loads that in preference to its own, and the neural pass - compiled as Shader Model 5.1 - then silently produces nothing while the install, the add-on and the frame counter all report success. The file now goes into the backup, the game uses the copy Windows ships, and Restore puts it back. Only ever when Windows has a newer copy to fall back on.

The in-game overlay

• The panel reaches the game on a display with scaling. Chromium paints the offscreen panel at the desktop's scale factor - 804 pixels wide at 150% for a 534-pixel panel - and every one of those frames was dropped by a size check, on any scaled display, which is most of them. The panel is resampled back to its transport size instead of being discarded in silence.

Wording

• The Feeder route is named for what it covers: "No DLSS / Incompatible DLSS", in all 38 languages. Thanks to @MaestroMetty (#48).

New in 2.2.2

A release about the reports people sent, most of them fixed at the cause.

Games it can now find and install into

• Executables whose renderer cannot be read are offered anyway. Protected builds, script extenders like f4se_loader, and launchers that start the real engine name no rendering API at all and were silently dropped - the "no 3D executable" report. They now appear in the executable picker, with the renderer shown as unknown for you to set.
• Ubisoft Connect games are discovered, alongside Steam, Epic, GOG and the Xbox folders.
• DXVK and vkd3d games are reported as Vulkan. The scanner used to call them DirectX and offer a route that installs a Direct3D hook, while the installer refused to overwrite the wrapper - a game that could not be installed with no explanation.
• Red Dead Redemption 2 follows the renderer you chose in the game, read from its own system.xml, instead of always reporting DirectX 12.

The in-game overlay

• A game that crashed no longer locks the overlay out of every game after it. Only one game at a time drives the panel, and a killed game could leave its end of the pipe open forever - the panel then said it was waiting for a design that never came.
• The game holds still while the panel is open. No mouse or keyboard input reaches the game, the way ReShade does for its own overlay, so a slider can be judged on one fixed shot.
• The Overlay page says what the service is doing - listening, connected to a game, or not running - with a dot for each state.

Installing

• Files are installed writable. Windows carries the read-only attribute across a copy and the payload inside the installed app is read-only, which is what "Unable to save configuration and/or current preset ... ReShade.ini" on the game's screen means. It also broke a second install and the restore after it.
• Feeder's Vulkan interop layer ships and is installed with a Vulkan game. Some drivers and emulators do not expose the KHR external-interop extensions, and the install then looked perfect and did nothing.
• An older NVIDIA driver no longer blocks OptiScaler. The neural-rendering model file ships with this app rather than being taken from the driver, so an older driver still runs - which matters because 616.64 and 616.86 are measured upstream to fault inside NVIDIA's own runtime, and people roll back deliberately. The ReShade and Feeder routes say so before installing.
• The professional Blackwell boards are accepted. OptiScaler needs a Blackwell card, and the check asked for a name matching "RTX 50xx" - an RTX PRO 6000 Blackwell was refused for being called something else.
• A component that antivirus quarantines says so. "Check your connection" was shown for every failure, including the one where the connection is fine and Defender removed the file after it verified.

Everyday

• An update notice in the sidebar when a newer release exists. One lookup, no identifiers sent, nothing downloaded or installed.
• Hiding a game is reversible: Settings lists what is hidden with Show again, and hiding asks first.
• Closing the window quits. The overlay service held an offscreen window, so the process stayed in Task Manager with nothing on screen.
• A faster, quieter start. Drive discovery no longer blocks on a cold WMI call, two game cards scanning at once can no longer erase each other's results, and the add-ons page does not re-hash every file on each visit.
• A support button on the About page, and in this README.

Components

DLSS5-Feeder 0.14.0-beta.4 (was 0.12.0) · OptiScaler DLSS-NR 0.2.0-patch1 (was 0.1.1.5) · LumeniteFX updated · ReShade 6.8.0 and dgVoodoo2 2.87.4 already current.

New in 2.2.1

• ⭐ In-game overlay: press F8 and the app's own panel appears over the running game — the same HTML, fonts and sliders as the preview, connected to the pinned RenoDX v4.7 build so the controls move the settings that are really loaded. While the panel is open the game receives no mouse or keyboard input, so the camera holds still and a slider can be judged on one fixed shot, exactly as ReShade does for its own overlay. Install it together with DLSS from one switch, choose your hotkey, or remove it on its own. It supports DLSS5-Feeder and RenoDX v4.7 only — the panel is built around that exact, hash-verified build and is not offered for OptiScaler.
• Overlay themes, including your own: Emerald, Azure and Amethyst, plus Create theme — pick an accent colour and the panel's other shades are derived from it, in the app and in the game alike.
• Per-game rendering API override: now optional, with Automatic as the default. Pick DirectX 8/9/10/11/12, Vulkan or OpenGL for a game that reports the wrong renderer; automatic detection is left untouched.
• Artwork for everyone: posters and banners come from Steam's public endpoints with no key, so every user sees the same covers and heroes.
• Some issues were fixed, including the overlay connection line that contradicted the CONNECTED badge, dialogs that stayed dark in the light theme, theme cards misaligned in Arabic/Persian/Urdu, and an updated overlay build that refused to install over the previous one.

Compatibility

Category	Support
System	Windows 10/11 x64; compatible 32-bit and 64-bit games
ReShade / Feeder GPUs	RTX 20 / 30 / 40 / 50; older-series support is reported by the bundled modified runtime's author
OptiScaler GPUs	64-bit games with native DLSS enabled. The bundled neural model runs on Blackwell (RTX 50 / RTX PRO Blackwell); an older card needs a modded nvngx_dlssnr.dll you supply, which is never overwritten. Driver 616.56 recommended
DirectX 12	Native DLSS, Feeder, or eligible OptiScaler games
DirectX 11	Feeder for 32/64-bit games; eligible OptiScaler games
DirectX 9 / 8	DX9: 32/64-bit; DX8: 32-bit, through dgVoodoo2 → DX11 → Feeder
Vulkan / OpenGL	ReShade/Feeder; eligible Vulkan games can also use OptiScaler
DirectX 10	Not directly supported by Feeder; choose DX11 when available
In-game overlay	64-bit DirectX 11 / 12 games with ReShade add-on support; DLSS5-Feeder and RenoDX v4.7 only

OptiScaler's DX11/Vulkan path uses a DX12 bridge with FSR output by default. For Vulkan backend changes, restore originals first. OptiScaler is not the emulator/non-DLSS route.

Emulators

Select the emulator folder and its active renderer, then use ReShade/Feeder.

Screenshots

Before installing

• Anti-cheat: red warning and optional confirmation, not a blanket block. Injection can cause crashes or account bans; the app never bypasses anti-cheat.
• Requirements: Feeder needs Visual C++ runtimes (x64, plus x86 for 32-bit games). Some components download on first use.
• Compatibility is not guaranteed. Keep backups; existing mods may conflict. Not every reported game crash is fixed.
• Linux/Proton: experimental community source only; no Linux binaries in this release.
