Here is CRT-Pi. You have to use masks though with WinUAE.

If you want more authentic masks, please use the modified _winuae.fx and D3D9.

Some options are removed atm, like curvature, but many folks don't like it anyway.

Great job, used WinUAE 3.5 and almost did it on my old crap netbook (30 fps) which isn't capable of doing ANY shader. I am going to try on the big screen later.

Edit: 3x resolution(open image in new tab). Not bad at all

Another interesting (and fast) shader

https://github.com/libretro/glsl-sha...rt-potato.glsl

Uses an external mask

CRT Potato seems to have ambitions to be the simplest/fastest crt shader around and in the right environment it suceeds.

But the actual code is mainly consisting from here unsupported variables like custom texture lookup, input size, output size and frag coordinates so the port would have to be a re-invention instead.

If crt-pi uses the "sharper" option it looks very similar and still runs decently fast (uncomment the SHARPER #define).

I also improved crt-guest to look a bit nicer and run faster, it's tweakable enough i guess.



Sharper setting:



Anyway i wouldn't use potato if pi runs fast enough...

CRT-Guest looks really nice in combination with an Aperture/RGB mask. Could you add bloom that look at least a bit like we know from CRT-Royale?

I adapted the DosBox Daum port of Crt Easymode Halation, where bloom is added. It works correctly only in D3D9 mode.
Has lots of options and looks better with the modified _winuae.fx from previous page.

Looks very nice, but it's unfortunately too demanding in 2x multipliers when i use the new lagless Vsync method. Can you improve it a bit? And maybe add saturation too?

Well i am happy how CRT-Pi looks, very close to how CRT-geom-flat would look and much more light-weight. It works well even on 8 years old laptops with Intel dual core and an old Radeon card. I didn't test but i bet CRT-geom wouldn't run well on such a machine.

Bloom/glow can be a bit demanding with single pass shaders, but i think i found a good compromise, still it isn't intel igpu material.

Started from scratch and implemented it in the fast crt guest. For reference the original lottes-bloom crackles even at 3x res, this one manages 4x without slowdowns on my card.

It has the standard options and some more bloom related.
Hope it works fast enough...

I have a Radeon RX 560. It's better now, but with the lagless Vsync enabled not good enough (38fps now, 25 before). Well, maybe it improves for me after more lagless Vsync updates from Toni. Thanks for the fast rework, looks really great and i like the more detailed glow/bloom options.

It can be made even faster, but has a tiny compromise involved. It looks OK, differences require a magnifying glass lol.

Hope this one goes over 60FPS...

@nobody: nice shots.

Edit: small bugfix in the shader, looks better now.

Yeah, that one works fast enough. Looks great after adjusting some values. Many thanks again. I guess this is it for now. Unless we see Vulkan/Slang support one day in WinUAE.

At Libretro the guys managed to do xBRZ in an arbitrary fashion, which i thought could be cool for WinUAE also.
The shader itself is a bit lighter then integer scale xBRZ, but i would advise to use it with 2x multiplier, is enough for 1080p.
You can also adjust the shader #define when using it with 1x - is around 4x faster, but not as crisp.

Happyhats!

I think that your shaders are very beautiful and realistic. They are helping to give a new dimension for the games I play on WinUAE. Thanks guest.r for coding a so valuable feature! And thanks for Toni, for coding WinUAE all these years!

I've recently become a fan of using D3D:Lanczos16 combined with the Rgb.png mask (both available in the standard WinUAE install). It just completely throws me back on how I remembered my old 'miggy looking on my cheap red plastic rimmed 14'' TV back in Christmas '91 (except I was running Kickstart 2.04 then rather than 1.3!):

The D3D11 xBRZ got some smoothing bugs to iron out it makes my screen go blank unless I start with no filter at first and switching it to that on my latest WinUAE 3.6.1.

It doesn't appear as smooth and appear to be worse than the xBR Level 2 Acc HiRes.
