Do the SUPER-XBR + Guest Advanced CRT Shader is very taxing on gpu or cpu? I have a intel i5 4750 and a 970 nvidia card and a 1080p screen,
I think it’s faster than ScaleFx.
uper-XBR only does a 2x upscale in X & Y then drops down to 1x in y and 2x in x, so resolution-wise it uses a lot less memory and gpu cycles. There are also other variants in there if you want to use Super-XBR with a lighter shader, or without reflections.

Thanks a lot for the detailed answer, love how it smoothes the pixel edges and gives a clean image without looking cartoonish

Hi! I found a bug in the dedithering… It’s more noticiable on the letters, it happens in every game… More noticiable in some games than in others. Here is an example…
Off:
On 4:Hyllian + stripes also happens in number 1, 2 and 3, but 4 and 5 are the most noticiable…

That looks fun, kind sharing your preset?

That looks like a vertical line bug. Not a checkerboard one.

I don’t mind to share it, but I need to know how to share the short preset. I’m not able to do it yet.
I’ve got the simple preset saving on. But can’t find where the file saves. If I save it with the name I want, It saves with the long preset…

These files save under Retroarch/config
Hmm, this is weird, it’s supposed to save a simple preset as well

Inside Retroarch/config, what I see folders of the games and cores, with it’s own slangp. But if I open them with notepad, it comes a long list… If I save them by a custom name, it saves in retroarch shaders folder…

Can you go to your shaders/save page and take a screenshot so I can see what it looks like?

My settings haven’t changed at all but I updated to your latest release. I’m getting the “failed to load shader” error on any core I use. Any ideas?

You have to go to Online Updater and Update Slang Shaders.

Actually I meant a screenshot of the save page inside Retroarch

I have a very strong feeling that part of @RetroGames4K’s issue is that he might have been saving presets with the same name and overwriting them.
I’ve run into similar issues in the past when (accidentally) not saving as a new filename when updating and modifying my presets.
I try to always save as a new filename to avoid this.
