Turning off Shader if it lets me increase the Internal Resolution Scale to 5x (for 1080p) and with Multisample Antialiasing set to 4x MSAA
Later, if I activate the shader, RetroArch freezes and I have to close it by force or it closes only with a Windows error message.

Yep. And trying that in the shader will crash Retroarch. You will run out of video RAM.
I can turn Beetle HW up to 4x but 8x crashes. (Even using the STD shader.)
If you really want to use 5x (for 1080) in Swanstation. Then be sure to turn off downsampling in the core options, you can turn MSAA up to 4x.
Then use the MBZ__3__STD__DREZ-1080p__GDV.slangp preset.
For my presets the reference shader can be changed to the DREZ-1080p also.
I love this shader pack, but i need a bit of help. I have retroarch and a romset for finalburn neo, it works perfectly, i even have the bezel project overlays. Problem is, some games, i dont know how many, are vertical and the shaders wont adjust.
i usually use by default in all cores: Video / Scaling / Aspect Ratio = Core Video / Scaling / Integer Scale = ON this way i always have the pixel perfect screen size, even if it does not match with the overlays.
But ofc for this shader pack i need to use:
But doesnt work in vertical games (ex: 1943/1942 series) i have to rotate manually for each game.
however if i set my default scaling settings and tune the shader: HSM_ASPECT_RATIO_MODE = “6.000000”
it will have the perfect pixel size and rotate automatically but i lose the fancy bezels and its reflections
Any solution pls?
Hi, how can I install that HSM Mega Bezel? I can’t use I download the base 2 files from onedrive but I don’t understand. I see too many files for too many users I’m Confused totally.
Welcome. To fix the issue go to Options and set Vertical Mode On. Then go to Shader Parameters and change
[Flip & Rotate]
Rotate CRT Tube: 1
This will only need to be applied to Vertical Oriented games.
Welcome. To “install” Mega Bezel place the bezel folder inside Retroarch/shaders/shaders_slang folder.
thank you!
but thats what i feared, i need to set for each individual vertical game, need to find a list somewhere.
Oh well the shaders are well worth the extra job! 
After you get your list, just put them in a separate folder. (i.e. FB-Neo_Vertical). Then create one Content Directory preset. 
What @duimon said probably makes the most sense but I just wanted to add to what @hgoda90 said and tell you after changing the settings be sure to
Go back > Save > Save Game Preset
so that the setting will be applied each time you launch the game.
You really have to take it step by step.
I download the zip then open it and Copy the bezel folder.
Then I go to where my RetroArch is installed and go into the Shaders folder, then go into the Shaders_Slang folder then Paste the bezel folder in there.
After that, you have to follow the setup instructions in the first post of this thread to a tee. Step by step…
Then load your game, go into the Quick Menu by pressing Start on your controller or F1 on your keyboard, then go into Shaders, then Load, then navigate to the Shaders_Slang, bezel, Mega_Bezel, Presets folder and choose one of the presets to load.
I was able to find a list of Vertical MAME games.

Which preset does that?
All of the ADV presets have this, the parameters are right by the MDAPT parameter before grade
CyberLab Mega Bezel Death To Pixels Shader Preset Pack is now to be installed in the RetroArch/Shaders/Mega_Bezel_Community_Collections folder!
The old Mega_Bezel_Community folder can (and should) be deleted.
hello friend I was adding these designs but I don’t know how to stretch the bezel to match the image?
Hi there check out the auto placement example in the examples package, or you can just adjust the position x offset near the screen scale parameters.
Also this is really off topic for Duimon’s thread, so this conversation is best done on the main Mega Bezel thread.
