The desync gets worse or better depending on the BIOS version

Analyze both BIOS versions using UEFITool and UEFI Editor. Check for differences in defaults. It takes some trial and error to find the correct menu.

I have a Z590 AORUS MASTER motherboard, and I've also noticed significant differences between different BIOS versions. My motherboard has 10 BIOS versions, but only the F9 version has the minimum input latency; the others don't. It seems that many problems stem from changes in the motherboard BIOS's underlying code, and are unrelated to your specific settings. This issue is extremely difficult to detect.

I can confirm that’s right—I have a GIGABYTE Z790 AORUS ELITE AX DDR4 with BIOS version F12. I’m sticking with this version for now; if I flash to a higher version, performance gets worse, but I haven’t tried a lower one yet. What BIOS version do you have? Also, just so you know, I’m not talking about that nonsense that everyone thinks is ideal. Sometimes flashing the BIOS helps for a few hours or days, and everything works perfectly, but then it gets much worse afterward. I’m ruling that possibility out. I confirm that I’ve noticed: if you change the BIOS version, it might get worse or better, and I test it for about a week—that’s usually enough.

This problem involves two issues. A specific BIOS version and sound card driver are required to solve everything, but some motherboards don't have a usable BIOS at all... Nowadays, all computers have two sound cards: one integrated into the motherboard and another integrated into the NVIDIA graphics card. On my computer, I have to install the NVIDIA's built-in audio driver and configure it to output sound through the NVIDIA audio output. I use the monitor speakers.

I've seen a gamer with perfect 0-latency. I guess he has a perfect motherboard and BIOS combination. I know he's using a 3060 graphics card with the 552.22 driver. I asked him about his computer configuration, but he wouldn't tell me his motherboard model, saying he didn't know how to check it! He's an experienced user; he couldn't possibly not know.

I suspect that might be the root of the problem. He doesn't want the truth to spread because it would affect his interests?

What is the revision number of your motherboard? I saw BIOS F9 when I wrote this.

Motherboard model: Z590 AORUS MASTER. BIOS versions F9, F4, and F5 work, but other versions don't. The problem seems to have started when manufacturers began introducing capsule-style BIOS. Of course, this is just my suspicion.

What is a revision? My motherboard's official website shows the last BIOS version as F11d, and the earliest version as F4.

You only have one revision, rev. 1.0; the company doesn't release any others, but other companies may have more than one.
