I have made some progress with this.
First the not so good things.
I cant get this running from the Lens, the game icon appears there,
but when I click it, only the game introduction video starts to run and it runs endlessly,
the game does not start although I hit the start button.
I start the game like this:
- sign in to Steam
- start the Cosmos link box
- start SteamVR
- start the right controller
- start the game with the controller, by clicking the game icon
However, it is strange that the game does not start every time, sometimes simply nothing happens when I click the game icon.
Then I close the Steam and VR stuff and repeat the procedure, with the next attempt it usually starts.
Good news:
I was able to get a pretty decent frame rate with new graphics settings.
Previously I had made the graphics settings in the game when not having the VR on. But it is like the VR version would be a different game with its own specific settings.
When I found the graphics settings in the VR game I tried putting all of the settings as low as possible.
Then the game was running with quite good FPS. The image quality was not very good, but not too bad either.
Next step will be testing and finding settings that would give better graphics, but not hurting the FPS.
