In short, direct users with video cards that only offer Vulkan 1.2, like nvidia's kepler, to use the 7.x-x branch. Vulkan database to check if you card has support: http://vulkan.gpuinfo.org/listdevices.php
According to DXVK: https://github.com/doitsujin/dxvk/wiki/Driver-support#dxvk-next-release
"Note: Nvidia's Kepler architecture (most GTX 600 / 700 series) is no longer supported. Please use DXVK 1.10.3 in combination with these cards."
The last Proton version compatible is the 7.x-x branch.
Regarding vkd3d, version 2.9 started requiring Vulkan api 1.3. The last Proton version compatible is 8.0-2.
For this family of cards, one could use the latest Proton if exclusively using OpenGL translation with PROTON_USE_WINED3D=1 and no dx12 at all with PROTON_NO_D3D12=1. Another option is to stick with the 7.x-x branch.
