Timing kits 2026-11-11: lyrics while the music plays, frame-time steadiness, two new exact test builds

on GitHub

Timing kits, version 2026-11-11 (experimental). Windows: download fsr4-timing-kit-windows-2026-11-11.zip, unpack it and run fsr4time.exe. Linux and Steam Deck: download fsr4-timing-kit-linux-2026-11-11.tar.gz, unpack it, and in a terminal in that folder run bash run.sh. The kit downloads its test builds itself on the first start (about 44 MB on Windows, 45 MB on Linux): you don't need the .pack or music-*.zip files below.

For the best results, run it with the processor and graphics in performance mode: a laptop plugged in, not on battery, battery saver or a power-saving mode.

New in this version:

• Lyrics while the music plays. With the music player on (Space during the runs), the line being sung shows at the top of the window, in time with the song. The songs carry their own timed lyrics.
• How steady each build's frame times are. Besides the average, the summary now gives each build's 95th and 99th percentile and how much its upscaler time changes from one frame to the next. Builds that skip work on some frames swing more; this shows it.
• What a new test pack measures. When the kit finds new tests, it first says in a line or two what they measure.
• Linux: run.sh asks the desktop not to blank the screen or go to sleep while the runs go (where systemd-inhibit works; otherwise it runs as before), and the report names the Mesa driver version and any RADV / VKD3D settings.
• The kit's DLLs are for timing only. The README and the program now say so: the test DLLs are compared with each other, not with AMD's picture, and are not game builds. Builds for games are on the Releases page.
• Two new test builds (n-exact-r3-hlx11, n-exact-r3-hlx11w32): this project's RX 7000 exact build with a different form of pass 11, ported from HelixSR's source (GPL-2.0-or-later, by lonewolf0622; credited in the kit's NOTICE.md). Same picture as n-exact-r3, checked byte for byte in this project's test harness; the kit compares them on your PC too. They run on RX 7000 and RX 6000 desktop cards; Windows reports from those cards are the ones that tell whether this form is faster there. Older kits get these tests too.
• Two more test builds (lt139-reference, lt140-test; a second test pack the same day, which kits download by themselves): a refined FSR 4.1.2 Lite test build without and with a new history rule at moving edges. The kit compares them with each other (what the rule costs on your card), not with AMD's picture. Wanted from every card.
• One more test build (lt141-test; a third test pack the same day, also downloaded by the kits themselves): the same refined Lite build as lt140-test, with the new rule computed only where it applies. Same picture as lt140-test, and it should cost less: the kit compares it with lt139-reference. GeForce reports are especially wanted for it.
• Kits from 2026-11-03 keep working and pick up new tests by themselves; they say this new version exists. The lyrics come with a new song pack that only this version takes.
• Reports from every card are welcome; GeForce GTX 16 / RTX 20, RX 7000 and handhelds are most wanted right now.

On Windows, it will warn about an unknown program, because the file is not signed; the source is in the repository (timing-kit/windows/fsr4time.c, fsr4update.inc, music.inc, timing-kit/linux/run.sh). Checksums: SHA256SUMS.

Songs: written for this project, sung with Piper text-to-speech and the "alba" voice (Edinburgh alba speech corpus, CC BY 4.0); music/music.txt in the kit has the full credits.
