New CRT shader from Guest + CRT Guest Advanced updates

[guest.r]

Hey there! I’m very happy for the nice feedback. Maybe i’ll (manage to) improve the existing features even more, i would be definitelly nice if some effects could get an upgrade.

@BT-Kimosabe

is it possible to make a AMIGA CRT preset for the reshade releases, like the ones on this video?

The effect in the video has two components which currently aren’t included with my shaders, namely PAL signaling and camera effects. There are existing PAL shaders available for Retroarch, but getting a nice cam effects shader could be a bit of a challenge. The latter is a layer which doesn’t actually contribute to the natural perception of a crt display, but much hype is nevertheless involved, because it’s the only connection to the retro feel for most of the viewers. Actually i might add a ‘cam’ pass sometime, but dunno at this point…

[BT-Kimosabe]

Crosire would work on that.

But that depends on asking him at reshade forums if he wants to implement on the next updates.

also here is a before and after of the same preset, but with dgvoodoo2’s stretched crt mode

I tested a pal pre-shader with the hd version and it can indeed contribute very nicely to the vintage look.

Amiga monitors are RGB, not PAL

[guest.r]

Dunno, since PAL is not a connection type.

https://wiki.amigaos.net/wiki/AmigaOS_Manual:_Workbench_Monitors#Video_Monitors

Video monitors, such as the Commodore 1084 series, accept only the standard Amiga 15 kHz scan rate (NTSC and PAL display modes); a television is considered a video monitor.

See https://en.wikipedia.org/wiki/Amiga_video_connector. You could also use RGB instead of PAL on TVs, if the TV had a SCART connector (which many PAL TVs had.)

You only got an actual PAL color signal if you used RF or composite output.

[guest.r]

I know what you mean, but it’s not commonly used to name an amiga cable connection type “PAL”, because it’s not entirely accurate.

[guest.r]

Fun fact is that most 1084 monitors could take a composite connection. Newer amiga models also had a composite output.

Here is a “shadowmask” preset example:

It’s using the HD version:

bloom = "0.450000"
mask_bloom = "0.150000"
bloom_dist = "1.849999"
halation = "-0.250000"
gamma_c = "1.325000"
gsl = "-1.000000"
scanline1 = "2.000000"
scanline2 = "20.000000"
beam_min = "5.500003"
scans = "1.250000"
scan_falloff = "0.300000"
shadowMask = "10.000000"
maskstr = "1.000000"
maskboost = "1.400000"
masksize = "2.000000"
mshift = "4.000000"
smoothmask = "1.000000"
deconrr = "1.000000"
deconrb = "-1.000000"
deconrry = "1.000000"
deconrby = "-1.000000"

Pardon the off topic here, but this cover seems familiar…

I’ll show myself the

Uh oh… which came first?

Manowar! Such class.

I ended up finding an interesting article about this, which you are mentioned

https://blog.johnnovak.net/2022/04/15/achieving-period-correct-graphics-in-personal-computer-emulators-part-1-the-amiga/#crt-shader

i would love to see this replicated on reshade, mainly to see how some dos games like WC privateer would look like

[guest.r]

The article is about how to set it up also, comes also with the reshade configuration. But you must use WinUAE for this. You can download the necessary files from the Blog’s page or trought this link:

If you are using standalone Dosbox (?) then just use the Reshade files from the above link.

Here is my first attempt with the Commodore 1084 slotmask preset:

It’s configured with the new HD versions:

bloom = "0.450000"
mask_bloom = "0.150000"
bloom_dist = "1.849999"
halation = "-0.150000"
gamma_c = "1.250000"
brightboost = "1.000000"
brightboost1 = "1.000000"
gsl = "-1.000000"
scanline1 = "2.000000"
scanline2 = "15.000000"
beam_min = "6.000005"
scans = "1.799999"
scan_falloff = "0.200000"
shadowMask = "5.000000"
maskstr = "1.000000"
maskboost = "1.400000"
masksize = "2.000000"
slotmask = "1.000000"
slotmask1 = "1.000000"
slotwidth = "4.000000"
double_slot = "2.000000"
mclip = "0.400000"
smoothmask = "1.000000"
deconrr = "1.500000"
deconrb = "-1.500000"
deconrry = "1.500000"
deconrby = "-1.500000"

Those look really nice. I’ll try your settings later. Thanks

[BT-Kimosabe]

Reshade was updated to 5.5.0 Addon SP only version is included too

[BT-Kimosabe]

here is the preset i used for those doom 3 screenshots

https://files.catbox.moe/y1u0se.ini

you may need guest’s bumpmaping shader

[RetroGames4K]

Just for curiosity… What it looks like? Doom?

[RealNC]

Uh, like the cover of Manowar’s album “Kings of Metal”
