If DriverVersion is not really related to vendors, then I think it would be enough to pick the highest "31.*" version and then use it for all vendors. I thought they would have different versions.

DriverVersion is related to vendors, sometimes. Here is an example of a rare case: ```C if (vendor == 0x10de && driverVersion >= 9999) { enable_cool_rtx_stuff();} ``` Proton or DXVK should be able to fix it.

Where did you see this code?

It's an example of what UE4 does.

Screenshots of that UE4 code.

As I said in my PR to Proton: UE4 expects ANY value in the driverVersion string.

I see. Adding a comment saying the last seven digits are the driver number would be beneficial. Also, please add a dot after the commit subject. And you can put the commit message body on a single line. I usually break at 100 characters. Otherwise, it looks good to me. Thanks for looking into this.
