Valheim crashes – how to fix

The good news is that the developers are aware of the problem and are working on a solution. In the meantime, you can try to aleviate the issue by turning down the graphical settings in the game, and using the GPU control panel to force it to prioritize performance and set Vsync to fast.

Other things you could try include disabling the Steam overlay, and forcing the game into exclusive fullscreen mode. You can do this by right clicking on it in the library, then selecting launch options and entering “-window-mode exclusive -screen-fullscreen” (without the quotation marks).

There’s a special uninstaller you can get from their website if you’re not sure what exactly to remove.
