Pretty sure this is a dupe of https://github.com/doitsujin/dxvk/issues/4006
It absolutely is, thanks.
So this is a Source thing, good to know, will help a lot more games than Black Mesa then :)
EDIT: Oh, it's an Nvidia issue then... RIP.
Is has been reported to Nvidia
Apparently Ada Lovelace GPUs are safe from it, but Pascal, Turing, and Ampere are affected (at least).
I have a Ada GPU and can reproduce it. In a apitrace at least
This is the guy that tested it for me, it looks correct here, hopefully that's not an other issue on top of it!
(This is on Windows):
It looks like the fog issue isn't a duplicate after all, but a result of using the option
d3d9.forceSwapchainMSAA
when not using the option, things are normal (at least the fog opacity is)
since it's a custom config, I'm not sure it's worth investigating, I'll close this issue then.
It's been here for many versions but I didn't think of reporting this as an issue because I didn't want to be a bother,
but since Black Mesa may reintroduce DXVK as an option (because it comes with many benefits)
I feel like it's important to talk about it:
DXVK vs native D3D9:

seems to do it with lens flares too, possibly other transparent textures like coronas etc...
