After initially submitting I was made aware of the fact that gl and vulkan desyncing between one another is an issue only on my PC. Thanks to -7's efforts in pinpointing the cause of the issue, as noted in the submission thread, I was able to resync the first two floors relatively easily. I later managed to resync 4 more floors, and the final 3 I ended up redoing from scratch, which resulted in better floorgen RNG for Sheol and saved 38 frames over the submission.
Made this a while ago, figured it wasn't really worth submitting but might as well put it up here. Syncs on 1.4.3 with the same settings as the no level skips submission or on the newest interim build (28/04/22) with clock_gettime() monotonic enabled.
