Epic Roller Coasters problem

Hello,

Anybody uses this game here with the 5K+? I like it, it’s cool, simple, and nice to show to people who discover VR. Unfortunately, one of the last updates of something (game, Steam VR, Pitool or who knows, maybe the Nvidia driver) has broken it, as soon as it starts loading it’s a total mess flickering, stuttering etc… impossible to use.
I’ve posted in the steam discussion for the game, seems I’m not the only one. But would be nice to hear from other Pimax users.
