Any progress so far?

Hello,
The "Update 3: Asus sent me beta BIOS, currently testing." seems to be the last reported state, dating back to September if I'm correct.
Are the tests still going, or was the issue fixed in the meantime?

Being a Strix Scar 18 user (G835LX.327) I can confirm the issues are far from fixed. GPU instability related to MUX switch handling still there. This causes all the other system latency and other reported issues.
No update in sight. Possibly ASUS has abandoned any fix.
Possibly @Zephkek was silenced. 😟
