#102

After a lot of experimenting I think the resolution settings are just off / significantly worse. I can’t get a sharp+blended picture like in the old way. (ignoring the Integer Scaling issue for now and comparing)

My Update Wishlist in order of priority:

  1. Return to the old scaling method
  2. Fix Integer Scaling
  3. Add Mask 14
  4. Add new subpixel options (number 10 because it’s not even close to the same priority as the others - edit: the forums change the number 10 to a number 4, they assume I was stupid I guess!)

Did my best to get the blending the same. Jobima Sharpness sample:

@PU786 maybe there are some bugs that happen when I did update it, I will check, thank you for the report

what “Old ReShade” you test with? DevilSingh original one or my update

#104

Ah thank you, I couldn’t remember his name! DevilSingh yes.

#105

so the problem start with my update to crt-guest-advanced-2025-11-30-release1 ?

#106

Yeah that one is borked. Same as above screenshot.

good to know that (the circle of suspicion has become smaller), now maybe it’s my updates or maybe its the Aspect Ratio changes of DevilSingh, so can you check this? https://pastebin.com/S4rEgVvp it’s DevilSingh one but with copy/paste mistake fixed

CRT-Guest-Advanced, HD and NTSC for ReShade!

I would probably forgo (do away with) the Aspect Ratio changes. They seem to work right as it is in DevilSing’s fork.

That fork you just linked has all the issues. Integer Scaling is broken. Adjustments to Resolution numbers don’t blend properly until you enable Performance Mode. And the resolution numbers needed for what you would expect to be a 480p ratio, like 854x480 are instead, … wow, 2560x480?

#109

you mean https://pastebin.com/S4rEgVvp ? then it’s something in Aspect Ratio changes of DevilSingh (even if you didnt use the new Aspect Ratio things)

#110

and to be sure, that https://pastebin.com/S4rEgVvp should replace the other one (if you have them both you will see problems and errors, it’s reshade limitations)

#111

That one works! Tried to send you a friend request on Discord.

#112

the Discord in my main PC which I will not have access for some time

so that mean it’s something in crt-guest-advanced-2025-11-30-release1 update I did, I will check when I can

@PU786 I did try to debug it but still cant find why yet, it happen with 240p too

I find a small bugs that I fixed https://pastebin.com/4E60Zm5R but still has ghosting!

are you sure https://github.com/Jobima1st/CRT-Guest-ReShade/blob/Jobima1st-patch-25-11-30-r1/Shaders/CRT-Guest-NTSC.fx is also has the same problems? if so can you share the settings in ReShadePreset.ini?

#114

I didnt have the time so I did use free claude and seems it find more than 2 bugs, the ghosting is fixed! https://pastebin.com/JpzJ8QK8 , Edit: I did clean “ai” hallucination, so I think this is the final changes https://pastebin.com/eJ2KaruX

can you try and see in your end?

#115
  1. Good news is that Integer Scaling is fixed.
  2. Good news is the same resolutions I put into Sing’s fork seem to produce the intended blending.

Bad news is that outside of Performance Mode, things still don’t look right and you can’t use it to understand what Performance mode will look like. Very much broken.

Do you think it will be much work to add in Mask 14 (which would become Mask 15 here)??

Will edit in pics shortly.

#116

that already added, but there was a missing change that claude mention and add, it’s in both pastebin links and you can test

#117 
if(shadow_msk==15.0)
{
mask=0.0;
pos.x=floor(mod(pos.x,5.0));
if(pos.x<0.5)mask    =0.0.xxx;else
if(pos.x<1.5)mask.r  =1.0    ;else
if(pos.x<2.5)mask.rg =1.0.xx ;else
if(pos.x<4.5)mask.gb =1.0.xx ;else
mask.b=1.0;
mask=clamp(lerp(lerp(one,mask,mcut),lerp(one,mask,maskstr),mx),0.0,1.0);
}else

I think that’d be the code for it…

Oh no, you’re right. It was in there and working.

#118

Sing’s fork:

OGReShade
OGReShade3840×2160 3.06 MB

New Jobima w/fixes:

JoReShade
JoReShade3840×2160 3.24 MB

So as you can see it gets covered in these odd temporal dithering lines for some reason.

#119

maybe it’s another reshade limitation, I will see later

anyway I did fix the original CRT-Guest-NTSC.fx https://github.com/Jobima1st/CRT-Guest-ReShade/blob/Jobima1st-patch-25-11-30-r1-fix/Shaders/CRT-Guest-NTSC.fx too

But it’s working before, so something still needs fixing. In the meantime I can certainly use the Sing Fork to preview Aspect Ratio adjustment needs, however working on the sharpness is already a certified nightmare of Guess --> Check --> Uncheck --> Re-guess

Still suspicious it’s related to this Aspect/Buffer thing. That stuff seemed to work exactly as expected in the Sing Fork…

#121

dont know, but if it work fine with Performance MODE ON then I dont think there are something that need to fix, I may check later anyway
