Swanstation Core - Graphic Glitch

[imadeput0287]

Hello,

I have problem when use Swanstation as a core on RetroArch Win64. On every game I got graphic problem when the character move.

My PC Spec I7 3770 8GB of Ram GTX 1650s Windows 10 Pro x64

I have try to install VC Redist 2015-2019 but no luck. For the setting I have no change and there is no error on log.

Maybe something that I miss?

Thank you.

This is not a glitch. It’s called “combing” and is a result of weave deinterlacing. I don’t recall whether the core also includes other forms of deinterlacing (for example, bob deinterlacing will avoid the lines but the screen jitters up and down 1 pixel per frame).

It won’t occur on every game, as not every game uses interlacing all the time, though Tekken 3 does and many games use interlaced mode in the menus.

If you like you can use the deinterlace shaders by hunterk to remove interlacing with great results:

A couple of deinterlacing shaders

I made a couple of shaders to deal with interlaced content, figured I’d post about them here. They all take the weird, woven-field output from emulators and do different things with it. interlacing.cg takes the fields and blanks out half of them, alternating each frame. This basically makes it act like typically interlaced content you would find in a broadcast situation. bob-deinterlace.cg shows alternating fields line-doubled each frame, which causes characteristic judder (i.e., ‘bobbing’). I…

Instructions:

A couple of deinterlacing shaders

The shaders in the ‘misc’ directory don’t have presets, as they’re usually used in conjunction with other shaders. You just need to load them manually by incrementing the number of passes by 1, then scroll down to the new pass where it says ‘N/A’ and navigate to the shader you want, then hit ‘apply changes’.

Note that best results are with “Shader #0 Filter” set to Nearest. “Linear” results in some interlacing but is still better than default.

I just tested it on Swanstation and it works, just like on Beetle PSX. I use “bob-interlacing” which adds very slight flicker but I don’t notice it during gameplay, only on still screens like the pause menu.

Hi guys I got it fix by disable interlaced, I got the advise from duckstation git Now I can play Gran Turismo 2 with PGXP active without bug on the tires and roads (Beetle PSX HW still not fix the bugs - though i feel beetle core should be more accurate).

Thank you.
