First stop for any problem

DLSS5Converter.exe --selftest 2> report.txt

That runs a real conversion end to end — imports PyTorch, checks CUDA, estimates depth, evaluates DLSS, converts an SDR image and an HDR one — and prints your GPU, driver version, RenoDX add-on version and what the add-on itself said. Most questions answer themselves from it, and it is the right thing to attach to a bug report.

The four most common reports

"It looks identical." Update your RenoDX add-on first — an out-of-date renodx-dlss5.addon64 produces exactly this, with every indicator green. Then click Difference, which shows what changed, amplified, with numbers.

"Everything is green and it still fails." Update your NVIDIA driver. This is confirmed: 572.83 on an RTX 4070 Ti SUPER passed every indicator in Check runtime, including the test evaluation, and crashed on every real conversion. A driver update alone fixed it. There is no published minimum, because DLSS 5 is not released — run the latest Game Ready driver.

"nvngx_dlss.dll was not found" while looking at it. Put the files in dlss_files\ in whatever shape they arrived; the search is recursive and opens zips. Better: click Find my DLSS files…, which searches your Steam libraries, Downloads and Documents and copies a matched set in. If DLSS 5 already works in a game for you, that game's folder is what it is looking for.

"My export is only 3840 px." Two different settings. Max size is the resolution DLSS runs at — that is where detail comes from. Save result… asks for an output size separately.

Things people miss

Compare styles. Natural and Cinematic differ by about as much as the neural pass changes the image at all, so leaving it on the default is a real choice made blind. The button next to Difference runs both and shows them side by side with locked zoom and pan.

Video. The Video tab converts a whole clip and keeps its audio. Each frame is an independent conversion, so it stays stable, and it exports H.264/MP4 (hardware-encoded) that any editor takes.

HDR. .jxr from Xbox Game Bar or NVIDIA capture opens directly, and the whole pipeline stays in linear light — highlights survive through DLSS and come back out as .jxr or .exr. .exr and .hdr are read as linear too.

Sequences and folders. A second tab converts image sequences with your renderer's own depth pass, which is what makes them temporally stable. Apply to folder… on the first tab batches unrelated images at whatever settings you just tuned.

What this is not

It does not ship, link to, or help you obtain nvngx_dlssnr.dll. That is a leaked pre-release NVIDIA binary; you point the app at your own copy. There is no downloader and there will not be one.
