Hey! Thank you very much for making a game for Linux - few people would go for it. But I ran into a problem. The game does not start, in the terminal it gives such an error
For some reason, it is not indicated anywhere that the game requires OpenVR, and I have Vulkan support, if needed
P.S.: I forgot to say that I tried to run the game on the laptop's discrete graphics card, but that didn't help either
Hi! Thanks for reporting the issue. From what I already know this is kind of a rare case. Right now I'm trying to reproduce the issue to figure out the reason. Regarding OpenVR, this is just a warning, no need to worry about it. It will be removed in the next patch.
I'll be back as soon as possible!
Could you please tell me your OpenGL version? You can use the following command and tell me what is the output:
glxinfo | grep version
You may need to install mesa-utils package in order to do this:
apt install mesa-utils
Also, if you have Vulkan support, the output of the following would be really helpful
vulkaninfo | grep Version

Hi again,
Found a solution
Need to export or use VK_ICD_FILENAMES correct for my card drivers

To run on an Nvidia graphics card, I use the variables __NV_PRIME_RENDER_OFFLOAD=1 and __NV_PRIME_RENDER_OFFLOAD=1 - this is how I ran glxinfo to display information specifically about the Nvidia graphics card. With these variables, all games on Steam also work for me. However, your game refuses to run on both the Intel video core and the discrete Nvidia video card =(
In both cases, the launch of the game freezes with the message "Unable to read VR path registry"
Okay, I got it. Regarding the VR log, this is just a warning present due to a packaging mistake.
Unfortunately, I do not have a solution for this concrete case. I can say that all the reported issues with Linux were related to the video driver in one way or another. I will do more research about this case.
Once again, sorry for the inconvenience
