Can’t get shader/ shader presets that I have uploaded to pi to show in UI
-
Without be sure, i think slang shaders needs vulkan.

You've downloaded a lot of shaders, but the Pi4 is not powerful enough to run the most demanding ones - I think ScaleFX is one of those.
Basically, the shader support is tied to the video driver used in RetroArch.
Driver Preset extension Shader repository gl
(default).glslp
upstream (RetroArch) is glsl-shaders, default RetroPie installs a subset of them from a separate repository glcore
(Pi4/GLES3 needed).slangp
upstream (RetroArch) is slang-shaders vulkan
(Pi4/Pi5, but with bookworm RaspiOS)idem idem So when you're browsing for a preset, look where the preset files are located and try to load it, but I very much doubt that Scale(N/F)X are usable on a Pi4.
In order to choose a different set of presets/shaders, you can change the video driver from the Configuration Editor and then your next RetroArch start-up will look for the corresponding extension when you browse the shaders folder(s). -

I agree because I have no clue what I'm doing :-)
And again thank you for everything you have helped me with lately. I would've never got this far without your and the others' assistance here on the forum.

Well that's a bummer. I've heard that is one of the best ones for bringing the pixels to more of a new style art.
That is the look I am going for, I know it isn't traditional but I would like to make these games look a little more HD/ smoothed but crystal clear. I had used ScaleFX on a windows machine in the past and it did such a good job. I follow you though on the not powerful enough.

Thank you for this table. Very helpful!!

So I will try this again when I get home tonight but I'm pretty sure for whatever reason, when I search within RGUI and the same location where I have put all of the files in the filesystem through WINSCP, nothing is showing on the RGUI side even after a reboot.
For instance, see WINSCP screenshot below. When I get home tonight I will post a photo of me searching in RGUI on the shaders area and I don't believe any of those slangp files will show at this location:
/opt/retropie/configs/all/retroarch/shaders/scalefx

Ok, so depending on what video driver is set in the configuration editor, RGUI will filter what you can see on the UI. With this being said, I will change my driver to glcore, and use the .slangp file as seen in the screenshot below called "scalefx-aa-fast.slangp" if it shows up in RGUI after the reboot.
Thank you for such a detailed response @mitu. I will test this when I get home a report back the result here.--> It's my thoughts that I have not changed my video driver from default so the .glslp files should have been showing up on RGUI and I don't think they were.

You can use the default video_driver, there are
.glslp
presets for ScaleFX in theglsl_shaders
repo. It may not even run, due to the lack of GPU features - may require an OpenGL version which is not supported by the Pi4's GPU. I also expect that switching to theglcore
video_driver will not be enough, since the shader may expect a higher OpenGL version than what's currently supported by the Pi. -
@mitu Everything is working excellently now following your advice/ guidance!! Thank you so much again on helping me get everything working from the start up until now.
Very happy with the results of the cabinet build!!
-
@mitu I follow you. Everything is showing up now as you explained. Over the next few days I will test some of the different shaders. I guarantee you are correct so hopefully I can track one down that does similar effects as scalefx but is less taxing for the system.
Thank you again!!

@mitu I think this is what happened to me on the issue we've been talking about in another thread. Linked below for other forum members:
I ended up downloading the slang and glsl files you spoke of in the previous post.
Can you possibly lead me to some preset files that will give me the scalefx look of almost like a smoothed pixel. (Artistic style).
I was really trying for the scalefx-fast as I heard that was built specifically for the pi but I couldn't get it to work.- So I pretty much deleted all of the contents in my shader directory and started with the downloads you lead me to. (Because most of what I downloaded originally wasn't working)
One last question I have is how do I know which shaders will work in retropie on the pi 4?
-- I noticed on the glsl shaders master gitub, "scalefx" is a selection. I imagine this repo is used for larger systems also (so no issue there).
But how do I know which preset could work for the pi 4 and retropie (or the answer is you really don't unless you research each one or test each one?)
Thank you for this. I think I got screwed up because my originally thinking on these shaders were if they were in the provided repos, they would work on pi 4/ retropie setup.

There are presets for ScaleFx for both
glsl
andslang
shaders in the Github repositories I mentioned before in this topic. I don't know of any other ones.I was really trying for the scalefx-fast as I heard that was built specifically for the pi but I couldn't get it to work.
Where did you hear that ?

Load a game without any shader applied and then use the RetroArch quick menu to load one of the shader presets you have downloaded - you can see if it works and how well it performs on the Pi.

I noticed this. No problem. I will test them.
Just to make sure I understand, you said that the scalefx would likely not working even if they are from the repo you linked me to, correct?

I am wrong, I went back to the reddit post I saw that on and that was for "Open EMU" not "Retropie", I apologize.

Ok, I follow you now. So the shaders at the github you linked me to would need to be tested to see how they will perform on the pi4. (These shaders are for the retroarch project but not a specific hardware)--> Thank you for helping me understand this.

Indeed.
