You can install vulkan-tools (ubuntu package name - not sure if it’s the same for your distro) and running vkcube. It’s a simple vulkan app that will display a rotating cube using vulkan. It will also spit out the GPU that it’s running on.

If it reports your nvidia card and the cube looks good then your drivers may be fine and the issue is with Steam and/or this application specifically. If not then there’s an issue with your drivers.

Occasionally when I’ve had a kernel update or something the nvidia drivers have gotten borked. Removing, re-installing, and rebooting has helped. Something like this:

<span style="color:#323232;">apt purge nvidia-driver-*
</span><span style="color:#323232;">apt install nvidia-driver-535
</span><span style="color:#323232;">reboot
</span>
