in the 850+ some hours I've played the only time I've had the game crash on me was right after an update that one of my mods conflicted with. I removed the mod and the game started right up again. And I'm running Valhiem on Linux using Proton so my system config is already on the edge of what IG testes against.

I would say the game is actually very stable over all and any issues with crashing that other people are commenting about are usually caused by something uniuqe to their hardware and OS. A video driver, antivirus, a malware infection, corrupted OS library, etc.

The devs do test before they release an update but they can't test against all possible configurations so there will always be the odd fringe cases where the game just flat out isn't stable for someone.

If your hardware is mainstream standard with an updated OS and clean filel system you shouldn't have any problems.
