Alphultima PURE 4K -- a crt mask based upscaler. $1000 Challenge!

Please let me know your thoughts! :blush:

I’d like to test, indeed! It’s always good when alternatives appear for RA! Congrats for your achievements! Unfortunately my Retroarch is hooked on a 1080p display and shaders quality is dependent on display characteristics. So, maybe I can’t compare these shaders. OTT, I’m not at home this week.

I’ll try it out. Where do I want to place these in my folder structure?

Thank you so much!! Well you could give the Alt Mask one a shot :slight_smile:

Cool! It depends on your OS, but just where you see any saved presets show up. Let me know what you think :slight_smile:

Here are the shots for the ALT MASK preset:

I guess I couldn’t figure it out. The shader fails to load each time.

Hmm note that it’s in slang format so the video driver in the RA configuration/video options should be set to Vulkan. Give that a shot!

Alternatively let me know which one you’d like to try and I’ll let you know the settings for each shader pass.

Just tried the ALT mask (1080p monitor here) it looks very nice! well done!

@Drybonz to make it load I had to change this line

shader0 = “…/…/…/…/data/user/0/com.retroarch.aarch64/shaders/shaders_slang/stock.slang”

with this

shader0 = “shaders_slang/stock.slang”

with this it loads fine from main shaders directory.

Thanks. With this change it will load but looks very weird as if some of the other elements aren’t loading and needs more line edits in the preset. I’ll take another look at it later.

Thank you very much! :blush:

Yeah not too familiar with that ha :sweat_smile:

Please let me know if there’s some reference guide that shows how to share saved presets (?)

I’m not sure there is a guide in the docs, but just make sure that the paths in your slangp files are relative, when they refer to a shader.

I checked the other presets and I think that in all 4 the line that I showed before has to change. Doing that they will work from the main shaders directory, if you want them to be in some other location you can use “…/” to go one folder up.

@djayjp @alderi3

try here, I just changed the reference of the first pass.

Just finished V2 of the ALT MASK preset that looks way better for 1080p!:

Alt Mask V2 for pre-rendered games:

1080P versions are now about 4x better!

The PURE version now basically matches the 4K sharp version and is suitable for 500 nit 1080P displays.

Version 3 of the ALT MASK preset is not quite as good, but is suitable for 250 nit 1080P displays.

NOTE: they won’t look right at other resolutions.

Would love to know your thoughts on the newest version @Hari-82 ! And sorry I don’t actually have a computer lol (just Nvidia Shield and my Android tablet) so that file issue might still be happening :see_no_evil:

Do I understand correctly?
This is a contest, you have to make a shader from the library look better than these?

Hey thx for asking! This is mainly about my work involving this new scaler/preset I’m showing, but yep you can also try to claim the $1000 prize if you can show a pre-existing shader that looks better than this (full terms & conditions in the original post :wink:)
