Thanks for all of the information you posted. This is a bit strange because the DREZ presets worked the last time I checked them. However I’ll check them out again soon.
A log might have been a great help. Please use pastebin if you’re posting a log though as they can get very large.
Don’t bother pasting the log. I found the issue. Try the Le’Sarsh_4K_Optimized folder, there’s a second DREZ file there. It seems to be missing from the other folders. You can try copying it and see if it fixes the issue.
Also, this issue seems to have been introduced in the latest version of my preset pack v1.14.0_25-01-24.
An easy workaround might be to reinstall v1.14.0_05-11-23 choosing not to overwrite any files with the same names.
I’ll see if I can release a fix for this as soon as I get a chance.
Thanks for posting here so that others may benefit.
What size is it and how far away from the screen do you sit?
Have you enabled any power saving features or adjusted the OLED Light setting on the TV?
What values have you set these to? Did you use RTINGS.com to get the peak and 240p Test Suite’s Grey Ramp to assist with setting the Paper White Luminance value?
If it’s still too dark then you probably need to increase your Paperwhite Value. Other than that you can increase the Gamma in the Shader Parameters.
Are you using BFI and also are you using HDR Game mode?
Isn’t per pixel local dimming the whole point of OLED technology? I’d probably leave that on if I were you but I never used a C1 before so you probably know better than me what that setting does and how it works.
Feel free to report back with your settings and after you increase your Paper White Luminance value.
How does the brightness look by default if you use my presets without adjusting your Peak and Paper White Luminance values?
my lg c1 is 55 inch, and I am setting about 9-10 feet aways from the tv.
I used Rtings for the HDR parameters and set it to 640 for peak and about 350-400 peak luminance. I used the snes 240p Test Suite’s with the Grey ramp and the color bar for the sub pixel layout.
I am using HDR with Gaming mode enabled. I am not sure if I enabled BFI or not but please tell me if I need to enable/disable the setting.
for the gamma there are so many gamma options. can you tell me which gamma parameter should I change.
I think I used the wrong term for this one. I meant ABL.
For the default peak luminance it works well with my HDR settings. But the white luminance values are too high for my screen. the colors are washed out or I am missing details (for example the clouds in mega man x or sonic 3).
its probably because my tv’s HDR is not bright enough (it got 6.9 in gaming mode according to Rtings).
Firstly Sony Megatron Color Video Monitor recommends an HDR600 display or better. I’m sure your C1 is capable of more than 600 cd/m².
Secondly here’s a comparison of my TV’s HDR Test results to yours in HDR Game mode.
2% Window - 652 vs 751
10% Window - 651 vs 747
25% Window - 413 vs 412
50% Window - 223 vs 277
100% Window - 129 vs 131
This might be a factor because the presets would have been designed with ABL on so if ABL is off then you might end up with higher effective Paper white brightness at similar settings to if ABL was on.
When Paper White Brightness is set too high, there’s clipping of the highlights.
Are you sure HDR is being enabled in RetroArch? Are you on the latest version of Sony Megatron Color Video Monitor?
I have 2 Megatron Preset packs now, do presets from both of them look too washed out or dark?
These settings seem par for the course for any LG OLED TV perhaps you can try 630 for Peak Luminance.
You should probably set Paper White similarly - which is what the current presets have it set to or try to get closer to 400 than 300, at the moment I’m experimenting with some upcoming presets with Paper White Luminance set to 430.
If that is set to that and all else remains equal in my presets, they would definitely look dark until you lower the Gamma (the last one).
Sometimes you can lose detail if Saturation is too high but if colours appear washed out then you might want to turn up the saturation.
A picture paints a thousand words. Feel free to post a screenshot or photo of the screen so that I can better understand what you’re describing.
You probably should disable it if your TV does not get bright enough with it on.
If you’re using an LG OLED TV, then the best subpixel layout is RWGB (WOLED) - 2.0.
My presets should look good then because this is similar to my viewing distance when I developed them.
Lastly, how does your TV fare using the default Sony Megatron Color Video Monitor Presets? Perhaps you can use those as a starting point?
For those who like Saturn emulation. My latest CyberLab Megatron NX Death To Pixels 4K HDR Shader Preset Pack should be a real treat. This is because I had inadvertently enabled "Horizontal Blending" in Beetle Saturn’s Core Options and this had a terrible interaction with the shaders when it came to resolution. I had compensated for this in my previous Saturn presets but I was never quite satisfied with the output.
All of that has been resolved now and I’ve updated the presets in my latest pack (only) to take the new Core Options into consideration.
The result is that Sega Saturn games should now look just as good as their counterparts on other consoles for the first time using my NX preset pack!
@Bigbang concerning the issue of my DREZ presets not working. I think I had plans to deprecate the old DREZ (base) preset after I had made a much better looking one, which was suposed to replace it.
I probably got sidetracked working on some other updates but had already removed the old DREZ ones and wanted to release an update which probably fixed and improved other things before I was finished working on the DREZ update.
At some point I might see if I can pick back up where I left off where that is concerned.
The biggest change in my latest CyberLab Megatron NX Death To Pixels 4K HDR Shader Preset Pack is the introduction of Near Field presets for all supported consoles.
This is due to a change in viewing distance in my personal setup which sort of makes many, if not most of my previous presets which were developed from a certain viewing distance not look quite as intended anymore.
Those who view from similar distances (and closer) to my new setup might probably welcome these new developments. Those new presets carry the suffix “Near Field”.
I apologize again for replying so late. Thank you very much Cyber for all the information given and answering my messages.
I guess I’ll just wait for that new update from you in the future and enjoy what is working for now which is very impressive and I’m enjoying it very much.
Since what you mention in the previous post also does not work for me unfortunately or maybe i do not understand well what files to move. But well I’m not impatient at all. I am satisfied with what works. And i thank you.
Still I wanted to ask you a question or rather ask you for a recommendation.
Using Beatle of Swanstation or any core scaling to 2x which preset would you recommend?
If you provide some details as to what you tried, maybe I can help you out.
Do you understand what I meant when I said you can reinstall the previous version of my preset pack?
If you try to do that the system is supposed to ask you if you want to overwrite any existing files with the same names.
You just have to say no and that should get the DREZ presets working again.
I recommend the newer DREZ preset though.
This really depends on what graphics card and display you’re using.
If your Graphics Card has 8GB or more VRAM, you should be able to do some upscaling without using the DREZ presets.
Also, if you’re using a 4K Display then I recommend trying my CyberLab Neo GX presets.
Other than that, just try all the presets with PSX in the names or read the full filenames and see which PSX presets seem interesting to you.
You can also browse through the posts and screenshots in this thread and see which presets look good to you.
If you have a 4K HDR Display (or just a bright display), I recommend you try my CyberLab Megatron NX Death To Pixels Shader Preset Pack. You can also give my CyberLab CRT-Royale Death To Pixels Shader Preset pack a try, unless you can’t live without the reflective bezels provided by the Mega Bezel Shader.
Lastly, if you wish to understand the capabilities of my preset packs a bit better, I suggest you read the entire first post of this thread at least once.
Soooooo, apparently my regular BSNES Core might have been inadvertently deleted at least a month ago and I didn’t realize it up now. So my latest SNES Near Field presets ended up being made for the BSNES 2014 Accuracy core.
When I tried them out using the regular BSNES, they looked more than just a tad blurry.
i watched at the path it looks of files why does [CyberLab Megatron Death To Pixels 4K HDR Shader this path shaders_slang/crt-guest-advanced-2024-02-29-release1 & not shaders/shaders_slang/crt
Guest.R updates his shaders quite often. Many times when this occurs, existing presets no longer look as intended so it’s a constant cat and mouse game.
With my original Sony Megatron Color Video Monitor shader preset pack, I asked users to install a specific version of CRT-GUEST-ADVANCED in its default installation folder.
The side effect of this is that if a user updates their shaders via the Online Updater, it will pull whatever version is the latest in the Repo which might replace the required version with a newer version thus possibly changing the way the presets look.
This new installation method solves all of that and makes things much more stable and consistent.
Hey, have only just stumbled across these amazing shaders for 4kHDR. I have been getting retroarch setup and running on AppleTV. Has anyone successfully got this pack running on AppleTV? From a fresh install went through the process of doing all the updates to generate the shader directories etc. Then followed retro-crisis YT for install. I did have to manually delete and replace files and create any directories that were missing because when you copy across to the Apple TV is seems to strip out directories and doesn’t overwrite files it makes a copy with (1) after it. Had a few goes and can’t seem to get it working. Can load other shaders. I was wondering if I needed to manually update a config file in text edit for it to play nicely. The retro-crisis video seems to make some assumptions about your current install and wonder if there are earlier packs etc I have to also install. Fingers crossed this works will be a game changer for AppleTV.
Greetings. I have no idea as no one has ever mentioned this to me.
Okay.
If you could somehow get your hands on a logfile and share it using pastebin that might help immensely in letting us know exactly where things are going wrong.
This is good. Which other shaders can you load?
What I share are mainly presets so if you can get the actual shaders to load (which my presets refer to) then you should be good to go.
It could be some path or filename issues for example the use of long paths and filenames or the use of spaces or case sensitivity that might be throwing a wrench into things.
Once you can get CRT-Guest-Advanced-NTSC, CRT-Royale (or Hyllian’s CRT-Royale Presets), Sony Megatron Color Video Monitor, Grade and/or Super-XBR stock Shaders or presets to load, you should be able to get my presets (which are just settings for these shaders) to load…eventually.
The RetroCrisis videos should be taken just as a visual guide to support what has been written in the readme.txt file or in the first post of this thread. Those text based installation instructions are pretty much all you need to follow and some instructions send the user to the installation and setup instructions of the various shaders themselves.
If the shader presets are giving you a headache and you would still like to enjoy my work, feel free to try my CyberLab Custom Blargg NTSC Video Filter Presets pack which is also available in the first post of this thread. This can be combined with even the most basic scanline and CRT Mask shaders available for some wonderful effects.
Other than that, once you have RetroArch installed then you might already have my 1st gen video filter presets installed in the Filters/Video folder (depending on the installation package).
These shader presets load fine even on my mid range Android phone so if your Apple TV is being fussy about paths and stuff maybe it’s more of an OS thing.
Thanks so much for getting back…I just did a fresh install trying to follow the readme and created a log. One point that I want to check…the read me asks to create a shaders_slang folder in the root of the retroarch folder to install crt-guest-advanced-2024-02-29-release1. I previously had been installing this into retroarch/shaders/shaders_slang…it didn’t seem to resolve it. Let me know if you can see anything in the log worth trying. Thank you!
Also in response to the shaders, I was loading shaders in the HDR directory and can get any of the “crt-sony-megatron-xxxx-hdr.slangp” shaders to load fine.
Hi there, so have been using the log now I know what I’m looking for and added as you’ve suggested, it then wanted an xbr directory that didn’t exist and a file which I had from one of the other packs.
It wanted this which I had from a pack and added
“…/shaders/shaders_slang/xbr/shaders/support/linearize.slang”
and this which I added
“…/shaders/shaders_slang/xbr/shaders/super-xbr/super-xbr-pass0.slang”
I’ve now got so far as the following error looking for “spline16-x.slang” which it is now asking for but don’t appear to have this file in any of the packs I’ve downloaded and my searching has turned up no results where I might find it. It feels like there is an install I’m missing.
Any ideas on what needs to be installed to solve the following?
[ERROR] [slang]: Failed to open shader file: “/private/var/mobile/Containers/Data/Application/5D7AD510-82CB-4511-BF2E-5268271AF7C8/Library/Caches/RetroArch/shaders/shaders_slang/xbr/shaders/support/spline16-x.slang”.
I’m glad you’re understanding how to use the log in order to see exactly what is happening behind the scenes.
From what you’re describing, it seems to me that you might need to use the Online Updater and update your Slang Shaders.
If the Apple TV is having some trouble pulling the updates and saving them in the correct folders then perhaps you might be able to use an Android, Windows or Linux device to use the Online Updater in order to get things in the right locations then just copy the correct Slang Folder structure to the Apple TV device.
Did you use the Online Updater to update your Slang Shaders? Also, there was a major reorganization of Shaders, presets and folders a few months ago, so it’s possible that your might not have the new folder structure if you haven’t updated.
By the way, what version of RetroArch are you using?
Hey @Cyber, it is 1.18 and I did run all the updates available with the retroarch updates menu including the slang shaders. It’s like the install is incomplete, I’ve deleted and done fresh install and updates a few times. The install is all controlled via Apple App Store, once it is installed you can access the install via your local network in a browser on computer to modify the install which is how I’ve installed the packs and some of the missing files we’ve been working through.
I progressed a bit further by installing Retroarch on my laptop and found those missing files, setup those directories…
This is now the current error.
[ERROR] [slang]: Texture name ‘PrePass’ not found in semantic map, Probably the texture name or pass alias is not defined in the preset (Non-semantic textures not supported yet)
[ERROR] [slang]: Failed to reflect SPIR-V. Resource usage is inconsistent with expectations.
One thing that’s really painful when you copy a folder to the Apple TV, it strips the folder structure and just copies all the files into the one directory. It’s really weird. You have to build the folder structure yourself and copy the files over folder at a time.
Hmmm…I’m tagging some folks who might be more knowledge in these aspects to take a look at this issue. It could be some sort of bug why certain shaders are not being downloaded when Online Updater is used to download your shaders.
Just by reading the error, this appears to be an error or omission in one of the preset files but not necessarily my shader Preset files. It could be in a shader that is being used. I doubt it’s coming from one of my presets. Can you try some other presets, for example the Near Field ones. Also, you can try my older Sony Megatron Color Video Monitor preset pack.
Also, you don’t actually require my Sony Megatron Color Video Monitor shader preset pack to take advantage of HDR, you can use any preset pack or shader preset, then enable HDR in RetroArch’s Video settings then adjust the Peak Luminance, Paperwhite Values and Contrast until it looks good on your display.
H i@Cyber
I have a question about ntsc filter. Is there any ntsc filter for Psx, or is it possible to create one?
I tried using this:
Blargg_SNES_Pseudo_PCE_PSX_SNES_COMPOSITE.filt
But I’m not sure if it works properly, the image is quite yellow.
I tried to combine this filter with shaders from Koko aio.
