New CRT shader from Guest + CRT Guest Advanced updates

New Release Version (2023-05-28-r1):

Notable changes:

  • no scanline mode bug fixed (deconvergence pass)
  • slotmask bug fixed with increased mask size
  • mask zoom support for enlargened (mask size) masks
  • mask “shrink” mode implemented, works very well, still could need more testings…
  • (the idea is to increase mask size and then downsample the mask to desirable width…)

guest.r how far behind is the online updater’s version? I always hesitate to use the latest version you are giving us because i fear that if I hit the online updater for slang it will revert/mess things up…

The online repo version is quite behind now, but you can just copy / paste the latest version over it without much issues, because mostly new features were added with some improvements.

When the latest version gets a bit tested i will ask @hunterk to update the repository.

As a fun fact, the version from a year ago is only like 2.5% faster with default settings, so there is really no need to worry about performance loss.

Are there any shader settings that impact performance in a notable way?

If you throw in magic glow, bloom, halation, mask bloom and mask interpolation at the same time there is up to 18% performance loss. Up to 20% with deconvergence added on top of all.

Using much more taps in the glow pass is also notable, but not too much.

OTOH interlacing and no-scanline mode increase performance quite a bit.

i have been out of the loop for a while focusing on other stuff.

No, no presets have been posted in this thread, but stay tuned…

Here is an example of the scaled mask 6 preset:

The catch is now different mask width 4&5 setups are possible, very nice for 1440p and 4k…

Definetely has that Trinitron look. Almost spot on, filter, mask and everything.

I tested it on my 4k TV and it looked even nicer. Great experience. I’m somewhat tempted to go 4k on my desktop also, but it could get expensive overall lol. :grin:

I’ve been trying to google and look at some of the thread for Real CRT vs shader comparisons and couldn’t find it. Did anybody do such comparison?

Hi @guest.r, I’ve got a question about Mask Zoom: is it normal that it changes the subpixel layout, from 3 to 4? Because that’s what happens if I use “Mask Zoom: 1” on a Mask 6 layout. I think it wasn’t that way with the second implementation, when you still had the 0,5 intervals.

Also, there seems to be some kind of disalignation, which also happens with Mask 10, but less noticeable.

Zoom on those images to understand what I mean, it should be noticeable even with the compression.

Mask 6 (1440p):

Mask 6, Mask Zoom: 1 (1440p):

Edit: the disalignation (look at the inner thighs).

Edit 2: Mask 7 and Mask 9 seems to zoom (1) without issues.

Edit 3: switching from RGB to BGR layout for Mask 6, Mask Zoom: 1 fixed the disalignation. Don’t know why, but it worked. I leave all of this stuff here so it can be helpful to someone else.

Edit 4: even by switching to BGR when zooming the mask I experience disalignation. Blue gets in place but other colors, like violet, disalign. Weird.

Yeah, this requires special handling at least. You can also try to downsample mask 12, maybe it works better. I remember having slotmask alignment issues and differences between different adapters in the past. It’s not bad to give it some attention.
