It's not bad. It's definitely got old Linux/Wine compatibility-in-progress vibes. I ran the beta alongside the Infinity client on pop_os 24.04 LTS. My microphone and controller would only work with GFN Beta; the UI was sluggish and playing felt like being stuck in treacle. It was the opposite with Infinity, which also looked a little better.

I switched to CachyOS this past week and now the microphone and controller work in both the GFN beta and Infinity apps with the caveat that the microphone is either too low in the mix or sounds messed up in the one game I've been playing as of late. It isn't the standalone USB microphone, which sounds crystal clear in Audacity and which I've tried in several USB ports. qpwgraph says it's the capture device for GFN as well. I haven't found a willing soul to subject to poor in-game VoIP audio yet to figure out if it's dependent on Nvidia VM lottery yet or something else.

Given how much support for flight sims and the like they're putting out with HOTAS and VR updates I hope they figure out how to make regular headtracking work too. Right now it doesn't work at all (at least on Linux, wouldn't know about 10/11) and especially won't if your headtracking software is a Steam purchase far as I know.
