Their drivers are getting there. I have not heard many bad things about Battlemage's driver support beyond typical launch day bumps, and would consider buying one myself now honestly.
Their biggest weakness is that their entire architecture is built around dx12 and Vulcan, it has NO hardware level support for dx11/9 or older graphics API's. The largest problem Arc had at launch was it would run modern games decently, but even games a few years old would run at single digit framerates (if at all!) as their driver tried to translate older api draw calls into a newer API, and very poorly at that. They've apparently vastly improved that translation layer by now so it's no longer a problem.
I'm not gonna lie, if you're having continuous driver timeouts that's probably a personal Windows issue. I had some issues with my 7900xtx until I just fresh installed Windows (despite the install only being a month old) and all those problems magically went away.
