Meh, nothing like having the official AMD video drivers crashing several times a day on Ubuntu with a flagship Sapphire RX 7900 XTX. And if you're extra lucky it will kick you out of the session too.
Yeah I don't think I've had a single crash with the mesa drivers after my overclock was dialed in. And I've ran some pretty janky stuff (like my vega 56 that was flashed with a 64 bios).
Yes, personal experience, but also from benchmarks, the open source mesa drivers are just faster at this point, unless you're turning on raytracing in everything.
How are Intel's drivers? My new PC has an A750 because I like to live dangerously. It's been great in Windows for the few games I want to play (the older stuff that has performance issues with Arc I'm largely not interested in or can play on my old PC)
Intel has historically had very good Linux drivers. Last time I checked (8 months ago), there were still some bugs when the cards were new, but I'm sure they're mostly ironed out by now.
The drivers themselves are fine, but the problem is game compatibility. Several games require you to fake your card vendor so that the game thinks you're on nVidia or something, but even then, there may be some compatibility issues.
