perseval-BLR/NeuralScreen

DLSS 5 NR on your whole Windows desktop, in real time with Boost, FG, etc. RTX 30/40/50, 12 languages, user presets, recording with audio, one-window mode.

NeuralScreen – DLSS‑5 neural rendering for the Windows desktop

What it is – A Windows‑only overlay that runs NVIDIA’s DLSS 5 neural‑renderer (the same network used in modern games) on every frame of your desktop. It can sharpen the whole screen or a single window in real‑time, optionally adding DLSS‑G frame‑generation.

Key capabilities

  • Neural Rendering (NR) – applies the DLSS 5 up‑scaling network to the captured desktop image, giving a sharper picture.
  • Frame Generation (FG) – optional DLSS‑G mode that interpolates extra frames (×2/×3/×4) to raise perceived FPS.
  • Per‑window mode – select a single window to process; the overlay follows moves and resizes.
  • Adjustable profiles – presets ranging from Faithful to Extreme; three built‑in models (Default, Natural, Cinematic) and sliders for strength, boost resolution, NR passes, etc.
  • Hot‑key control – all functions (toggle NR, FG, screenshots, recording, resolution scaling) are bound to the numpad; keys are fully re‑assignable.
  • Recording & Spout2 output – GPU‑accelerated capture (NVENC) and a Spout2 stream for OBS or other tools.
  • Multi‑language UI – 12 languages, light/dark themes, on‑screen frame counter.

Supported hardware

  • Requires an NVIDIA RTX GPU. Full support (validated) for RTX 50‑series; RTX 40‑series reported to work; RTX 30‑series unverified for NR and known to fail for FG; RTX 20‑series known failures.
  • Windows 11 (or Windows 10) with the latest NVIDIA driver.

Installation & usage

  1. Download the release archive, unpack anywhere (the bundle includes the required NVIDIA DLLs and a self‑contained Python runtime).
  2. Run NeuralScreen.exe (or NeuralScreen.vbs to bypass the unsigned‑publisher warning).
  3. The program lives in the system tray; press Num2 (Num Lock on) to open the overlay menu.
  4. Use the menu or the hotkeys to toggle NR, FG, change resolution, take screenshots, start/stop GPU‑encoded recordings, etc.
  5. To remove, simply delete the folder (the only external change is an autostart entry, which can be disabled from the menu).

Limitations & known issues

  • True fullscreen games cannot be overlaid; use borderless/windowed mode.
  • HDR support is experimental; recordings and Spout output remain SDR.
  • Processing resolution is capped at 2560×1440; output is always the native monitor resolution.
  • Latency of 25–30 ms (10–15 ms with Boost mode) – fine for everyday use but not suitable for competitive gaming.
  • Rotated displays (90°/270°) are not yet handled correctly.
  • Multi‑GPU and Windows 10 setups are experimental.

    OpenDLSS‑NR is a Windows‑only Vulkan re‑implementation of NVIDIA’s DLSS 5 Neural Rendering network. It reproduces the exact 71‑block Swin‑ViT model (FP8 on tensor cores) and provides both a high‑performance PTX kernel path and a reference GLSL path, plus a Filament demo and a WebGPU browser version. Users supply their own model weights; the tool can benchmark, verify bit‑exactness against NVIDIA fixtures, and run interactive demos.
