New CRT shader from Guest + CRT Guest Advanced updates

guest.r · 8 February 2023 17:44

New Release Version (2023-02-08-r1):

Notable changes:

Magic Glow hard-coded parameters are now available for normal tweaking, default look is a notch different, but barely notable (standard and ntsc versions).
Magic Glow has now it’s own parameter section + minor change in Glow parameter description (standard and ntsc versions).

Excellent work on this!!!

I was literally on my way here to post up two different settings for you to try out and get your opinion on, guess I’ll hold out and and see what this update is about to see if it changed anything, back to the drawing board lol. Thanks for the update.

Edit: looks like there’s been a little work done on magic glow. I’m assuming those new default settings is the “safe” settings to use if someone wanted to just enable magic glow and be done with it. The glow seems to display more “balanced” now. Not sure what you did but I’ll start playing with it.

Edit 2: Not bad @guest.r, I’ve managed to come up with something using these new glow settings. If you can please try to get this update to go upstream asap.

I really like this update, especially being able to adjust the “magic glow low/high strength” settings separately is useful.

Sexy pics there, you hardly post but whenever you do you always make it count. Yes @guest.r this update is the one, hopefully this one will be pushed upstream before I put the finishing touches on my next update pack, got a couple new goodies coming in this one real soon.

Edit: Also @guest.r, I noticed some slight frame dips in some of my presets, I thought it was just the ones where I combine them with other shaders but it also happens on my rgb one as well which is just your stock shader by itself. Frames go down to about 56-57 then back to 60 then sometimes wavers back and forth.

Not sure if the newly added magic glow is the reason but I noticed it on this recent update, I even get frame dips while in the menu.

A little new experimentation with magic glow.

I think the default value for the “high” parameter is a tad too much, so I’ve lowered it to 4. What strikes me the most is the color saturation (those blues!), even with the default “saturation” value and low bloom.

m_glow = "1.000000"

post_br = "1.100000"

I’m tweaking magic glow a bit atm, the blue saturation problem is solved i guess with my current private version. Presets which use the feature for increased contrast shouldn’t be affected, so no worries. As i mentioned before one can’t do such glow most properly, there is always a catch, but it’s getting better.

At a quick glance everything still looks the same settings wise, you haven’t added or taken anything away or changed default values of any of the magic glow settings. You gave it some kind of speed boost in performance? I don’t notice those little random frame drops anymore either in the few games I tested.

guest.r · 11 February 2023 11:33

I didn’t initialize new variables, reused some old ones etc. Register usage / caching do sometimes have a thershold for performance drops. A good example are rolled loops for the 2-phase pixel assembly in the ntsc shaders. Some gpu architectures got much stalled if this loop was not unrolled.

sonkun · 11 February 2023 11:39

I see, well that definitely fixed things on my end. Far as I’m concerned this update is the one, hopefully you can get this version pushed upstream to the repository asap. Also I can start getting my new shader pack ready for release.

guest.r · 11 February 2023 13:38

I’ll definitely ask for a repo update, but i guess it should rest a portion of time, like a good steak. Current version is quite complete, should do for quite a while. I’m still interested if there is some feedback or constructive criticism though.

Fab · 11 February 2023 14:05

Oh but I liked it.

I’m getting the hang of magic glow, it surely gets a cleaner and sharper image, nice blacks and such. But regarding fidelity it would be nice to have a CRT. At the moment I think I’ll keep using it and not the ordinary glow, the overall quality of the image seems to be better.

sonkun · 11 February 2023 14:33

So far everything seems good, it’s set up just right just gotta play around with it and get use to the new magic glow settings and find the look you like.

guest.r · 11 February 2023 15:23

Here is a screenie of a magic glow preset (ntsc):

ROBMARK85 · 11 February 2023 19:48

Hi Guest, I wanted your opinion and that of your community: I mixed, using the “Add” function of the early version of RetroArch, the ScaleFX shaders, your Sharpsmother and your Guest Advance CRT (in this order). For now I’m sharing screenshots taken with my smartphone (as soon as I can I’ll do it on my PC screen) to give and get a first feedback. Thank you!

ROBMARK85 · 11 February 2023 20:03

Same preset as before, but with mask 9 and slotmask active at 100 (and width value 1)

guest.r · 11 February 2023 20:29

You could also do some downsampling (in interlacing parameter options) to get a smoother image.

ROBMARK85 · 11 February 2023 21:43

Finally I went back, and went back to an old post of yours, and I re-tested a preset of yours that you had recommended especially for me (scalefx + fxaa) and I edited everything with your GDV Standard, applied the Magic Glow and the slotmask with mask 9 and the result is amazing. Only one thing, to increase the brightness do I have to act on gamma input or gamma output? Here are some shots taken from my brother-in-law’s TV:

guest.r · 12 February 2023 06:43

New Release Version (2023-02-12-r1):

Notable changes:

Magic Glow mask strength control implemented, very nice new combos are possible now.
Current presets aren’t affected (@sonkun…).
