Custom Shaders for GSdx

[gregory]

It used to work with opengl. Maybe it fails to pick up the file.

Would probably be efficient to just make an asmodean version of ReShade and just use that instead and remove the shader stuff from PCSX2. Now that ReShade is out and functional with everything, it'll be a timesaver for everyone else who manages the shaders and it would be one less thing to worry about. *Shrugs*

i dont want an external program/shader if that is what you talking about

I dont know but it say it "activates" and "deactives" when i hit home

[shinra358]

It's basically external already considering you have to constantly redo it every time you upgrade to a new pcsx2. Not to mention you have 10x more options and the ability to just junction these shader files to work along side it and it works with any backend. And it's only a folder and 2 files to manage. The only thing that's really different amonst them is Asmo's version of the fxaa in which I find better and the full screen smoothing. Everything else is already included and done. No fuss no must.

external to me is external program AKA ReShade and SweetFX to do the shading GSDX shader is included and integrated in pcsx2

Asmodean, are you planning on doing anything else with the PSX version of your shader suite? I hope so, your light attenuation shader showed a lot of promise and potential, at least for me.

[tsunami2311]

Update on OpenGL issue with GSDX shader. 2.20 has been fix (by gregory) for opengl but one must keep UHQ_FXXA=0 if it set to 1 It will break shader and no options will work in OpenGL. This only effect OpenGL, DX11 the shader works fine Hope fully Asmodean reappears and can fix UHQ_FXAA in 2.20 with OpenGL and then apply all this to 2.30

[Asmodean]

I understand that some shader code is causing problems for the OGL plugin?. If anyone can provide / has a list of problems with it. I'm not at home for a few days, but I'll try get them fixed the weekend, or sometime next week.

I'll probably try polish off 2.3 so it works as intended for both backends.

Sorry, I've not been around. I've been busy with other stuff. Also, (side note) The Witcher 3 launched recently, and I've been playing that. (been waiting for it for like 3 years lol)

[tsunami2311]

As far as i can tell with the code fix Gregory did to 2.20 gsdx shader , All the shaders effects seem to work so long as FXAA is not enabled. if FXAA is enabled it kill/breaks all the other shader effects from working. and if FXAA is only thing enabled it dont actual work either

Built in FXAA in the GSDX plugin works but fxaa in the shader file does not.


2.30 just dont work period in opengl. and welcome back asmodean.

Hey there! Thanks to GSdx FX 2.3 my ps2 games look perfect! I tried sweetfx and a lot of custom shaders, but tweeking gsdxfx had the best result. Geat job,Asmodean! You have my respects forever!
Here are some screenshoots of what i could achieve:
i focused on getting black color as black as it should be, maybe screenshoots look a bit dark, but ingame it's exetremely atomspheric.

and if someone is interested, here are my settings

Code:
