The Talos Principle: vulkan version doesn't work
donbastiano Nov 28, 2018
Hi, when I chose the vulkan API the game crashes with the message "Fatal error: Cannot set display mode". I searched but have not found a solution. The relevant part of the log says:
18:48:59 TRC:  Cannot get values for cvar d3d_bTripleBuffering. The variable is not declared.
18:49:08 LOG:  Clearing fullscreen flag on the window.

But the the extension is present

Vulkan Instance Version: 1.1.70

Any idea? I want to see if with vulkan the framerate is a little more "stable"

What version of Mesa are you using?
donbastiano Nov 29, 2018
I'm on Ubuntu 18.04.1 LTS so maybe my Mesa is a little outdated...
OpenGL core profile version string: 4.5 (Core Profile) Mesa 18.0.5
and so the kernel, 4.15.0-39-generic. RX 570 also here :)
If there isn't a workaround, I think I'll wait for 18.04.2 that is scheduled for February. I played for around 1 hour and the game wasn't smooth with many framedrops; maybe I'm wrong, but I expect that with vulkan could be a better experience.

Thank you

Yeah I would absolutely try a newer version of Mesa. Have you thought about trying a PPA that has a newer version? PPAs can be reasonably easily reverted if you're not happy with the result.

I am sure a few Vulkan parts are missing from that Mesa version. I actually use the Padoka stable PPA, though haven't tried Talos with Vulkan.
donbastiano Nov 30, 2018
I'm more for official solutions but maybe some PPA are used enough to be trusted and stable, also if maybe they are more tested with newer kernel. I have to see which one is more suitable, I just know the Padoka and Oibaf and have to see their difference.
I had some problem in the past but maybe at that time I had also fglrx, it is much better the situation now :)
Thank you again

Mesa version 18.2.6 isn't that much better. I don't know what happened but RADV has a problem with this title.
donbastiano Dec 1, 2018
I tried the Padoka stable but still the same problem... me! The game started properly (using OpenGL), then in the menu game I selected the Vulkan API and it auto-restart and crashes BUT I just noticed that when you launch the game it appears a menu where you can select the "normal" or the 64bit version So, solved with the 64bit version, I apologize.
