Ill give it a go it is the only VRR Desktop is it not?

it looks like you're using Steam Beta

You can try this. flatpak run --socket=session-bus com.valvesoftware.Steam

I have yet to have issues with Ubuntu based OSes, Fedora and Arch have been a pain in the ass for Gaming, flatpak saves some of this.

LMDE has some issue's if you don't know what you're doing, Linux Mint is based on Ubuntu, one of the most well supported Desktop Linux OSes in the world.

Also now you can get Linux Mint Edge with Kernel 6.2 or just upgrade the Kernel in the package manager with a few clicks, also Mint has a Driver Manager for Nvidia based GPU's.

Ubuntu Base is the Top OS for Gaming other then SteamOS 3 that does not have a Desktop OS yet, also SteamOS was Using Kernel 5.15 if you want to talk about outdated.

Ubuntu's core is to well supported by Intel, AMD and Nvidia, etc for me to recommend anything but a Ubuntu based OS.

Once Valve releases SteamOS Desktop i will most likely recommend it for Gaming over Mint/Ubuntu.

I have Intel Arc, RX 580's to AMD RDNA, and Nvidia Pascal to Ada Lovelace GPU's, Nvidia's support is just ugly outside of Cuda, AMD's Drivers are Good depending on what Mesa and Kernel, etc you're pairing up, Intel ARC is a work in progress maybe Q2 2024.

The Linux Desktop Drivers for Sound, GPU, Etc. are not well supported like Windows is, this has been a weak point of the Linux Desktop, and Gaming on Linux for 15 or so years the People working on Flatpak, etc and the People working for/at Valve has been the best to happen for Linux Gaming, also the hobbyist who make stuff like package mangers for Wine, write patches, test stuff etc.

If all fails it maybe supported in xpad.

sudo apt update

sudo apt install steam-devices

reboot

M.2 needs to go away it was made to not need a cooler, Good U.3 Drives are about $100 a TB and i hope they keep getting cheaper.

I ran with Linux Mint Mate for years with the Ubuntu test PPA for Drivers and a Nvidia GPU, also do a MemTest on your system for RAM issues. and you can install Kernel 6.2 as well with it.

Asrock boards was the same day and sold out the same day.

Are they doing to support SR-IOV this time?

So can it run Crysis at 60 FPS with the CPU only?

Something about it failing QA.

DDR5 has 265GB RDIMM's, and if you need more the PRO Boards have 8 RDIMM's.
