Pixel perfect scanlines!

[Trailblazer]

Since the developers didn't include the promised scanlines rendering mode at game launch (probably they will in the near future), I found out how to obtain pixel perfect scanlines through reshade by importing a shader from retroarch.

Here is the link for the retroarch shaders:

And here is a screenshot of Blasphemous with glorious scanlines and how I configured the shader:

Enjoy!

What is a Scanline?

[Tony]

CRT TVs had a resolution of 480i - 480 interlaced lines. Interlaced meant that every other line (even number, odd number) was refreshed every 1/60 of a second. This was a nice, high resolution but you could get flickering and fast movement would get telltale distortion.

Video games ran at 240p - 240 progressive lines. Every line was updated every 1/60 of a second. It did this by telling the TV to instead "double strike" the same line every time instead of alternating between even and odd numbered lines. This left thin black lines between the active lines.

These black lines came to be referred to retroactively as "scan lines" and are considered a key component of the classical "CRT feel" of old game systems. While developers didn't go out of their way to use scan lines, they were aware of their presence and had to design art assets around their presence.

Thank you.

How did you get this to work? I downloaded the shaders from the link provided but Reshade gave a bunch of errors and they wouldn't load...

yes this really compliments the awesome pixel art! i'm surprised there's not at least a toggle for scanline filter in options.

thanks alot!

i follow this reshade guide install instruction for dead cells except just point it to steamapps/common/blasphemous.exe instead and select Direct3d 10+. then hit uncheck all option after downloading the effects pack https://steamcommunity.com/sharedfiles/filedetails/?id=1145295249

but instead of using the crt.fx use the Geomcrt.fx from the retroarch shader pack https://reshade.me/forum/shader-presentation/2556-retroarch-shaders-for-reshade-3-0-ntsc-pal-added?limitstart=0
you extract it to the "steamapps/common/blasphemous/reshade-shaders/shaders" folder

then launch the game and once it loads hit "Home" key at some point to open the menu and check only geomcrt.fx and set settings according to in the screenshot OP posted https://imagizer.imageshack.com/img921/4959/J0XhFV.jpg

and be sure to check the performance mode box at bottom screen once you have the settings to your liking. then it'll auto load after each game launch.

also while in the reshade ingame menu you might need to click on setting and keep hitting Tab key in order to type in the correct numbers.

hope that makes sense! lol sorry if it's not :)

Difference between "pixel perfect" and "scale"??

[Trailblazer]

@ Fils du Masque, sorry i didn't have time to reply, been a hard week :D Squirrel Master did a very good job explaining.

Just a quick update, I found another shader: "Lottes CRT" - the scanlines are more noticeable and unlike the first shader I posted, it doesn't modify the color palette of the game.

here is a picture with the settings:

Thank you! This looks really neat, it goes well with this game. I copied your settings to give it a quick test, but I'll mess around with them later.

This took some tinkering to get looking just right, but what a GORGEOUS tool!
Turns out these scanlines are far better than the built-in ones that the devs added (dev scanlines ruin the color balance, turning browns into pinks)

I also got ReShade to do a similar job on Katana Zer0, and I'll be using it on FTL and Into The Breach next!

Thanks to Trailblazer and the folks in the links.
