Precision X has stopped showing in The Witcher 3 and it's only affecting this game as far as I can tell. It seems to have coincided with me launching the game from the GOG client to test some things as I usually launch The Witcher through Steam.

It's working normally everywhere else so I'm not sure what's happened. Would appreciate any ideas.

GOG updated to patch 1.22 just yesterday, it could be a patch issue...

*Solved* There is a DLC game overlay that can be installed in the GOG client that was causing the problem. Uninstalling it has fixed it.
