How can I use shaders under the vulkan driver? I’d appreciate step by step. Thank you!
There’s not much to it. Go to the online updater and fetch the slang shaders. If you’ve already got games running in ParaLLEl, just hop back into the menu, go to the quick menu if you’re not already there, go down to ‘shaders’ and then ‘load shader preset’ and choose which one you want.
I don’t see the option to update slang shaders – only cg and glsl. Do I need to be on a nightly to see it? Thanks for your interest!
whoops, my bad. You’ll have to download them from here instead:

Thanks!
Unfortunately I still can’t get them to work. I placed the entire shaders in \retroarch\shaders\slang-shaders-master
And went to Shaders > Load Shader Preset > Slang-Shaders-Master>CRT>crt-easymode.slangp
doesn’t work
manually adding it also doesn’t work.
Thoughts?
Hmm, that should work. Is it giving you any errors?
Nope, it just doesn’t work
Do they work with other cores under the Vulkan context? Can you post a log of you trying to load one?
The Cores I tested seemed to run fine with vulkan but they crashed if trying to force slang presets. If I load slangp shaders, I don’t see any visible change and if I exit and enter again, there are no shaders selected at all.

Hmm, that’s very strange. I don’t see it reporting any slang errors (or anything at all, other than the stock bits), but I assume you tried to load a preset somewhere in there…?
Yes, I did. Like I said, nothing happens. I’ll wait – thnx for help
Any news on this? I’m having the same issue
do you have a log? are there any errors reported?
This is me trying to load the crt royale preset with paralel and vulkan:

Ah, that’s because the push_constant feature was added after the 1.3.6 stable release. It should work in the nightly builds, if you care to update. If not, hold off a bit because 1.3.7/1.4 (whatever we decide to call it) will be out relatively soon.
Thanks alot for the advice 
I look forward to the update
