doing some quick benchmarks with and without the scx LAVD scheduler enabled, on my uBlue image with kernel 6.9.12-205.fsync.fc40 (same as Bazzite):
up first is Total War Warhammer 3's battle benchmark at 1080p, running on Proton 9.0-2
image 1 is without LAVD, image 2 is with
very similar average framerate, but a bit smoother in the latter?
much more noticeable difference on the Immortal Empires benchmark
image 1 - without LAVD
image 2 - with LAVD
next, the FFXIV Dawntrail benchmark on the High (Desktop) preset, at 1440p via Lutris
slightly lower score with LAVD enabled, but very close
