NeuralScreen proves DLSS 5 neural rendering works desktop-wide — on a leaked runtime

NeuralScreen wraps NVIDIA's DLSS 5 neural renderer around your entire Windows desktop — not just games that have been patched to support it, but every window, video, and photo on screen at once. The mechanism is a fullscreen overlay that captures the display, runs it through the same neural network DLSS 5 games use, and composites the result back at native resolution before you see it. The latency sits at 40–60 milliseconds normally, dropping to 17–20 ms in Boost Mode — tolerable for casual use, not for competitive play.

The hardware story is honest and specific. RTX 50 and RTX 40 cards work natively. RTX 30 support was restored in version 1.5.1 via a universal runtime and an architecture spoof. RTX 20 (Turing) cannot run the neural pass at all — the runtime returns a FeatureNotSupported error — so the program starts and the menu works, but nothing is processed. Optimus laptops fall back to GDI capture on the iGPU display, which is slower but confirmed functional.

The resolution ceiling is worth knowing: the network refuses to process frames larger than 2560×1440. Output is always your full native resolution — the trick is a residual composite that layers the network's result onto the original 1:1 frame, so text and UI elements stay sharp even when the network is working on a downscaled input. Each step down the resolution slider buys roughly 50% more frames at 2560×1440 on a 4K screen, which is a meaningful trade-off for slower cards.

The bundled nvngx_dlssnr.dll is the leaked 310.8.0 runtime. The README states this plainly under the license section and marks it research-only. That single fact shapes everything about how this tool can be used — it is not a product, it is an experiment built on redistributed proprietary code. The anti-cheat warning is similarly direct: a process injecting nvngx.dll plus a fullscreen overlay is exactly what those systems flag.

True fullscreen games are unsupported by a Windows rule, not a software choice — the overlay cannot draw over exclusive fullscreen. HDR is also unsupported; you need to switch to SDR. Windows 10 with multiple NVIDIA cards or a second monitor is described as experimental, built from user logs rather than tested on the development machine.

The interface covers 12 languages, recording works via Spout2 output to OBS or through single-window capture mode, and the whole thing ships as a self-contained archive with its own Python runtime — nothing is written outside the folder, and deletion is just deleting the folder. For anyone curious about what DLSS 5's neural rendering actually does to arbitrary content, this is the most direct way to find out.
