The Linux DLSS panel has grown into a full Proton Upscalers panel — one place to set up DLSS, FSR 4 and XeSS launch options for your Proton/Wine games, whichever GPU you're on:

  • DLSS Ray Reconstruction & Frame Generation overrides (NVIDIA) — the panel now covers RR presets and an FG override alongside the existing SR presets, matching the Windows per-game DLSS dialog. New "Latest" and "Preset J" SR choices too. Works on any Proton, including Valve's
  • One-toggle DLL upgrades — flip a switch instead of memorising PROTON_DLSS_UPGRADE / PROTON_FSR4_UPGRADE / PROTON_XESS_UPGRADE. These use the built-in downloaders in GE-Proton, Proton-CachyOS and Proton-EM to keep upscaler DLLs current without touching game files, with optional on-screen indicators to confirm they're active
  • FSR 4 on RDNA3 or RDNA4 — the panel detects your GPU and picks the right FSR 4 path, recommending RDNA3 mode automatically on RX 7000 cards
  • Per-game validation — select a game and the panel shows which Proton build it actually runs under (read from Steam's own settings) and greys out toggles that build doesn't support, so you can't generate options that silently do nothing on Valve's Proton
  • Copy-paste anywhere — output is a standard ENV=... %command% line for Steam's launch options, and the same variables work in Heroic and Lutris environment settings

Seems cool but getting an overlay stating " dlss ask - do not distribute - contact NVIDIA ro obtain DLLs for your title" and rather not see that.
