NeuralScreen
**NVIDIA's DLSS 5 neural renderer, applied to your whole Windows desktop in real time.** Everything on screen — games, video, photos — goes through the same neural network that DLSS 5 games use, and comes back sharper.

*Everything lives in one menu inside the overlay. The Before / after wipe slider splits the screen down the middle so you can see what the effect is actually doing.*
What you need
- Windows 11
- An NVIDIA RTX card. What works, honestly:
- Nothing installed. The release archive brings its own Python.
Trying RTX 20
Turing is below the minimum architecture - no runtime build makes the neural pass run on it (0xBAD00001, FeatureNotSupported). The program will start and the menu works; the picture is not processed. No workaround exists.
Install
- Download the archive from Releases
nvngx_dlssnr.dll (165 MB, too big for GitHub to keep in the repository,
so it ships in the archive instead).
- Run
NeuralScreen.exe.
NeuralScreen.vbs next to it does the same
thing.
There is no installer and nothing is written outside the folder. To remove it, delete the folder.
Do not use it in competitive online games. A process named nvngx.dll
plus a fullscreen overlay is exactly what anti-cheat systems look for.
Using it
The program sits in the tray (with a taskbar button) and draws over your desktop. Press Num2 for the menu. The hotkeys live on the numpad, so Num Lock has to be on - with it off those keys send Insert/End/arrows instead and nothing happens.
| Key | What it does | |---|---| | Num2 | open / close the menu | | Num1 | neural rendering on / off | | Num3 | screenshot | | Num0 | start / stop recording, with sound | | Num4 / Num6 | processing resolution down / up | | Num5 | process one window instead of the whole screen | | Ctrl+Alt+Q | quit |
Every key can be reassigned in the menu, under the sliders icon.
While the menu is open it takes the mouse and keyboard, so it works on top of a game. Closed, clicks go straight through it as if it were not there.
Startup and mode switches do not flash: the overlay appears with the first real frame, a brief blur-with-spinner covers the pipeline rebuild.
Whole screen or one window
NeuralScreen renders the whole screen by default. To process one window instead (a game, a browser): point at it, press Num5 or pick Select window... in the menu. The overlay follows the window. Back to the whole screen: Num5 again or Fullscreen in the menu. Minimising the window pauses processing.

The dot next to your graphics card is green when neural rendering is actually running on it, red when it is not.
The settings worth touching:
- Profile — how strong the effect is, from Faithful to Extreme. Start
- Before / after wipe — leaves the left part of the screen untouched so
- Resolution the network runs at — one slider. At the top it is your whole
Everything else — which monitor, whether the menu opens on launch, starting with Windows, key assignments — is behind the sliders icon.
Recording and screenshots
Num0 records what you see, with system sound, into an MP4 in
recordings. Num3 saves a screenshot. The menu shows up in both if
open - on purpose.
Record the processed picture externally:
- OBS (recommended): launch with
NS_SPOUT=1(environment variable,
set NS_SPOUT=1 then NeuralScreen.exe). The worker publishes the
output as a Spout2 shared texture - add a Spout2 Capture source in OBS
(free plugin) and record. Works in full-screen mode too. Off by default.
- NVIDIA App / OBS display capture: use one-window mode - point at the
If something is not working
Nothing appears after launch. Check NeuralScreen.log next to the
program; the most common cause is a missing native\nvngx_dlssnr.dll.
The overlay is invisible in a game. True fullscreen cannot have anything drawn over it — a Windows rule. Switch the game to borderless or windowed fullscreen.
The menu pointer is missing or frozen. A fullscreen game hides the system cursor; the overlay only shows the system cursor. Borderless fixes it.
The numpad hotkeys do nothing. They need Num Lock to be on. With Num Lock off the numpad sends Insert/End/arrows and the keys simply do not exist.
The picture is soft. Put Resolution the network runs at back to the top of its slider.
A key does nothing. Something else claimed it; reassign it in the menu under the sliders icon.
The menu is slow in a heavy game. At 4K the pipeline can take up to a second per frame; a press may feel lost. The picture is the priority.
Known limitations
- True fullscreen games cannot have the overlay drawn over them — a Windows rule. Borderless or windowed only.
- A second instance is not guarded — close the first one first.
- The window list shows every visible window; Num5 takes the one under the cursor. A second monitor works but was not tested with a window between them; the menu position in window mode starts bottom-right.
- HDR displays are not supported: switch to SDR (Win+Alt+B).
- Pipeline latency is 40–60 ms — fine interactively, not competitively; processing resolution is capped at 2560×1440 (the network refuses 4K), output is always your full native resolution.
