Can't run vkcube on latest nvidia driver

Hi guys, I'm trying to run vkcube on my arch system and I can't get to run. once I try to run it exit saying " 1 physical devices" and "segmentation fault, core dumped". Dont post code directly because my system is on spanish.
Also I try to run the game "Talos Principle" and when I try to change API from OpenGL to Vulkan and game enginre restarts, it say "no screns found"
Same error when trying to execute vulkanCapsViewer, this app says me "could not enumarted device count!" (looks like its a grammatical error)

My system is running arch stock 4.5.4-1 kernel with Nvidia 364.19-3, also with vulkan-icd-loader installed

If you have any questions about this problem, please feel free to tell me. Any ideas will be welcome.

Thankyou so much

Re: Can't run vkcube on latest nvidia driver

by removing vulkan-intel pkg from aur, now vulkanCapsViewer reports no error and works fine. the game talos principle now dont show any error but screen turns black when switch to vulkan api into the game. I have tested the game dota2 in vulkan mode adding "-vulkan" to the launch parameters and works fine however vkcube still in trouble.

thats the output when i try to run vkcube:

[predacon@predacon-8320 ~]$ vkcube
1 physical devices
vendor id 10de, device name GTX 970
Violación de segmento (`core' generado)
[predacon@predacon-8320 ~]$ 
.

any help will be welcome

Re: Can't run vkcube on latest nvidia driver

I had trouble too with vkcube.
I got TTP to launch if you add this startparameter:
+gfx_strAPI "VLK"

Enter it under: Game -> right Click -> Preferences/Details (the last entry) -> set Startoptions
Then run the game in 64-Bit mode and Vulkan should be active.

Re: Can't run vkcube on latest nvidia driver

thankyou for your reply.

I tired to run with "+gfx_strAPI "VLK" with same result as changing the API to Vulkan into the game however found a solution for nvidia cards here

so, first start the game with opengl adding to the launch parameter

+gfx_strAPI "OpenGL".

then, deactivate VSYNC into the game and delete two files named Talos.ini. to find it try this

locate Talos.ini

and finally change game parameters back to vulkan

+gfx_strAPI "VLK".

Now Talos principle runs fine, but there is a bug changing between apis direclty into the game.
On my GTX970(1455Mhz) and I5-6600K benchmark without time limit on talos gives me 68.0 FPS for vulkan and 68.8 FPS for OpenGL

Still not found post or solution related to vkcube. maybe only run on intel GPUs?

Re: Can't run vkcube on latest nvidia driver

Thankyou for your reply CromatDragon. I've seen links you suggest me but my problem its related only with vkcube app.

In fact, my vulkan support works properly with dota2 and talos principle.

but all the ways thanyou for your help smile
