Gaussian Blur / Bloom / Unsharpmask

It is a working shader, i use it in games. The number of fetches is so high because you need a stronger blur for effects like local contrast, in the gauss shader you do 18 fetches because of the separate horizontal and vertical passes, if you did this in 1 pass it would be 81 so the multipass way should have been faster, but it isn't which is quite strange.

i tryed too disabling all effect in sweetfx, but the result does not change

i try with TCPIP code now.

edit: if i paste TCPIP code i get errors in compiling
I do not have the necessary knowledge

there is some tutorials to understand something?


PS: Neverwinter online is free 2 play

I'm downloading Neverwinter right now, I'll see if I can figure out the problem.

Are you getting the same result when using it with other games?

The code that TCPIP posted might work as a custom shader in SweetFX, it won't work as is in a .fx file though.

In the meantime you can try using this one . I fixed the part Crosire pointed out. I've also added an option to use bloom along with blur or sharpening, still a work in progress but it's been working fine for me.

EDIT: Just tried Neverwinter and it crashed just like in your video. No clue what the problem may be but I'll see if I can figure it out.

Ok thanks, tomorrow i will try with Insurgency and Arma3, but if you have the same problem others games are relative.

This is great! Thanks for working on this. The gaussian shader/s are pretty essential if you ask me.

Here are working files based on lumasharpen.h:

What is the difference from your and CeeJay version?

this is only for blur?

The difference is in method and the result, CeeJay's version sharpens the image, mine is for local contrast.

No problem! And I agree. I particularly like the bloom and hoping to eventually get the sigma, threshold, and exposure working, but I'm learning as I go so it may be awhile.

Updated the OP with a new version. Just added some more options, still a work in progress.

Still causing Neverwinter to crash which means there are probably other games that will have issues. If anyone has any ideas on how to fix this let me know.

Thank you for this, Ioxa ^^

EDIT:

Just one question. Isn't there a way to turn this extra effect on and off, right?

Easy, simply add "toggle = [KEYCODE];" right after "enabled = true;" in the technique line (which btw. would benefit from a nicer name, something like "technique GAUSS ...") and replace "[KEYCODE]" with the hexadecimal code of the desired key taken from here .

No problem Wicked! Is there a specific effect you want to turn on and off or do you want to do what Crosire said and toggle everything in GAUSS on and off?

Also, thats a great idea Crosire, I'll add that in.

On a side note, I've been having some issues with this recently. I tried using it with DOF and it gave everything a red tint. I tried restarting the game and sometimes it would crash and other times it would keep running but with the red tint. Then I tried turning off DOF but the red tint remained. I even reinstalled ReShade + SweetFX, made sure that worked fine, then added GAUSS again, and I STILL got the red screen along with occasional crashing. Using that same GAUSS.fx file in another game worked just fine. I'm going through each effect one by one trying to find the problem but I can't figure out why the problem persisted after reinstalling everything and going back to a previously working configuration.

OpenGL game + you are on NVIDIA, right? Cause then you ran into the NVIDIA driver bug I'm wrapping my head round for a while now already, switches the red and blue color channel under OpenGL in certain circumstances.

Thank you Crosire and Ioxa. I am using the Pause key "0x13" to toggle the Gauss effect ^^. I am liking it this way, to use one key to toggle SFX and the other for the extra files.

Yeah, I'm on NVIDIA, but the game is D3D11. ReShade + SweetFX together work just fine, it's just adding GAUSS that throws everything off. Considering I don't really know what I'm doing, I'm sure the problem is caused by something I've done. I think I'll step away from it for a bit and come back to it when I'm less tired.

I added that toggle key in on mine too, nice to be able to toggle it on and off real quick.

Kurtferro! I didn't see a way to PM you so hopefully you're still checking in here once in awhile. I got it working with Neverwinter, at least on my end. I'll upload the file here for you to try out. I still have a game it's not working with but I'm starting to think maybe that game got corrupted somehow, if thats even possible. Let me know if this works for you!

I try now!

edit: crash again^^ with red and black screen before freeze

Sounds like the same problem I'm having with a different game, no idea what is causing it.

Wow, this looks even better than I thought. Is it possible to add texture filtering to this?
