About 20 minutes ago, I just flashed the new 2403 for my ROG Strix Z690-F Gaming WiFi, and so far it seems to be OK.
Haven't seen any noticeable improvements to performance but I've not had any problems either.
My system seems to be running the same as before, except the fans don't seem to ramping up as frequently as before... So maybe that's an improvement.
I'll keep an eye on things and if anything changes enough, I'll be back to post it here.
