There was a proton 5.13 release which made some weird stuff with it.
try to switch to older proton 5.0 to confirm if your vulkan drivers work there. If they do then we can check whats needed for newer proton.

Reinstalled my whole system and you are right with Proton 5.0 i have no problems to start. But native games without proton don't wanna start.

whats the output of glxinfo | grep render

also to check native games, you could start steam from terminal and then try to start the game, it should show whats wrong with them.

glxinfo | grep render
direct rendering: Yes
    GLX_MESA_multithread_makecurrent, GLX_MESA_query_renderer, 
    GLX_MESA_query_renderer, GLX_MESA_swap_control, GLX_OML_swap_method, 
Extended renderer info (GLX_MESA_query_renderer):

    GL_NV_conditional_render, GL_NV_depth_clamp, 
    GL_ARB_conditional_render_inverted, GL_ARB_conservative_depth, 
    GL_NV_compute_shader_derivatives, GL_NV_conditional_render, 
    GL_EXT_render_snorm, GL_EXT_robustness, GL_EXT_sRGB_write_control, 
    GL_NV_conditional_render, GL_NV_draw_buffers, GL_NV_fbo_color_attachments, 
    GL_OES_element_index_uint, GL_OES_fbo_render_mipmap, 

found out it seems like its only one native who does not work, so it might be a problem with game itself.

But i would have one more question.

My System has a Hybrid Mode but in the Hybrid Mode, Vulkan won't get any good performance. But i found:

"Hybrid

Hybrid graphics mode uses both the integrated GPU and the discrete NVIDIA GPU. Applications will use the integrated GPU unless explicitly requested to use the discrete GPU.

Vulkan applications must be launched with this command to be rendered on the dGPU (NVIDIA):

__NV_PRIME_RENDER_OFFLOAD=1 <application>

GLX applications must be launched with this command to be rendered on the dGPU (NVIDIA):

__NV_PRIME_RENDER_OFFLOAD=1 __GLX_VENDOR_LIBRARY_NAME=nvidia <application>

Hybrid graphics mode is available on 19.10 and later."

so i tried

NV_PRIME_RENDER_OFFLOAD=1 steam

is there anything i can do?

Is steam a Vulcan application?

tried also "NV_PRIME_RENDER_OFFLOAD=1" in steam launch options. Won't work as well.

your glxinfo output shows you don't have nvidia drivers.
I have no experience with switchable graphics so i dunno what to do there.

shouldn't there be a place like this where you switch your GPU?



and iirc theres a thing on your top panel also where you can do that, or at least i remember seeing it on the interwebs somewhere, but i have no experience with it myself

Hm i use the drivers from system76. It cam out of the box so not sure why there not showing as nvidia drivers.

For switching between graphics i use this:

https://support.system76.com/articles/graphics-switch-pop/

this is the output of glxinfo | grep render in NVIDIA Mode:

so if i understood the website correct with the code "NV_PRIME_RENDER_OFFLOAD=1" i should could start in hybrid the nvidia but i only get this

NV_PRIME_RENDER_OFFLOAD=1 glxinfo | grep render
direct rendering: Yes
    GLX_MESA_multithread_makecurrent, GLX_MESA_query_renderer,

    GL_NV_conditional_render, GL_NV_draw_buffers, GL_NV_fbo_color_attachments, 
    GL_OES_element_index_uint, GL_OES_fbo_render_mipmap, 

but if i use the second code i got this "__NV_PRIME_RENDER_OFFLOAD=1 __GLX_VENDOR_LIBRARY_NAME=nvidia <application>"

ok start steam like this works __NV_PRIME_RENDER_OFFLOAD=1 __GLX_VENDOR_LIBRARY_NAME=nvidia steam

seems like steam is not a vulkan application but can translate then to vulkan?

How could i get set this, without using the terminal? So everytime i start steam yes uses this code?

make a new launcher into the menu with the command __NV_PRIME_RENDER_OFFLOAD=1 __GLX_VENDOR_LIBRARY_NAME=nvidia steam

Call it Steam (Nvidia) or something... i bet gnome has the create launcher option somewhere... havent used gnome for a while though.

It seems like i only had to do this one time. Right now everytime i start steam it just works great!
