FSR 4.1.2 DLLs (2026-11-05): faster 4.1.2l-exact and 4.1.2l-lossy, most of all at 1440p and on the Steam Deck; same pictures

7 days ago

New: faster Lite builds, most of all at 1440p and on the Steam Deck, with the same pictures. exact and lossy are the files of dll-2026-11-01, byte for byte. Everything that changed, in figures

How much faster than AMD's FSR 4.1.2 Lite, Windows timing-kit reports, previous release then this release, on RX 7000 and RX 6000. How much faster than AMD's FSR 4.1.2 Lite on the Steam Deck and the Steam Machine, previous release then this release.

Less time per frame than the same build in dll-2026-11-01, timing-kit reports, median, moving scene:

4.1.2l-exact 4.1.2l-lossy
RX 7000, Windows, 1080p / 1440p / 4K 1% / 9% / 1% 0% / 5% / 0% (other archives' form)
RX 6000, Windows, 1080p / 1440p / 4K 2% / 9% / 2% 2% / 5% / 2%
Steam Deck, 800p / 1080p 10% / 2% 6% / 3%
Steam Machine, 1080p / 1440p / 4K 2% / 11% / 3% 1% / 7% / 2%
  • Faster at 1440p and 800p on every GPU that measured them: RX 7000, RX 6000, the Steam Deck and the Steam Machine (800p: RX 6000 and the Steam Deck, whose screen size it is). Both Lite builds gain most at these two sizes. Passes that do no work for the picture are also no longer started (the 1 to 3% at 1080p and 4K).
  • 4.1.2l-lossy for RX 7000 is its own form now (same picture): the other archives' form rendered 2.4% fewer frames than dll-2026-11-01's on an RX 7800 XT in Shadow of the Tomb Raider under Linux, this one 2.3% more. On Windows RX 7000 one report so far (RX 7600): 0.3 to 0.7% faster than the other archives' form, whose figure is in the table above. 4.1.2l-exact is one form in all four archives.
  • Worse: nothing slower beyond the spread of single runs (4.1.2l-exact on a Radeon 780M / Ryzen Z1 at 1080p measured 1.7% slower in two Linux reports).
  • Picture: 4.1.2l-exact is AMD's Lite picture byte for byte; 4.1.2l-lossy gives the same picture as dll-2026-11-01's. It changes the picture against AMD's: read its WARNING.txt.

Each holds exact, lossy, 4.1.2l-exact, 4.1.2l-lossy and WHICH-SHOULD-I-CHOOSE.txt. Windows 10: use 7-Zip or the .zip. Not for RX 9000; never in online games.

Checked: the test rig, Linux (Proton), every size; timing-kit reports on Windows and Linux from RX 7000, RX 6000, the Steam Deck, the Steam Machine and built-in graphics. Not checked: GeForce and Intel Arc. Windows will warn about an unknown file; checksums: SHA256SUMS.
