Updated my RetroArch build. Tried loading some of the shaders I was able to before and getting crashes. Not posting for immediate resolution, just a heads up to the team. Appreciate the continued work/support 
Hello, can anyone help me solve my problem? When I try to emulate SNES and apply these very cool shaders, my image is very badly distorted as you can see on screenshot. (look at my ball, it’s not even rounded, LOL). I’d rather like to see picture without this deformation. Is there a way to do this?

I needed some help please: to improve the performance of the DREZ presets you mentioned in the package update, for performance reasons, I need to remove or disable the reflection on the screen, which parameters should I adjust? Thank you very much for helping.
If you are using the ntsc variant you should not use the horizontal sharpness stuff in the regular guest settings and instead use the parameters in ‘[ NTSC FILTERING OPTIONS ]:’
And if you want to point out something which is incorrect the only thing to measure against is the Guest.R’s standalone Guest Advanced NTSC.
To do this you need to start fresh with a base STD preset with no other changes except in the [ NTSC FILTERING OPTIONS ]: and compare to the same changes in the standalone guest ntsc. You will also need set the aspect ratio to full and turn off curvature in the STD preset to have the image scaled the same so a direct comparison can be made.

Looks like a similar issue as before where it is initializing at a very high resolution which is overloading the GPU memory. I’m not sure why more people aren’t running into this. You could try bsnes HD beta, it seems to not initialize at as high a resolution

To improve this the best thing to do for this particular game is to adjust the top and bottom cropping in the shader parameters until it looks better.

You can turn the reflection off but I’m not sure it would result in better performance, because the passes would still be there. There aren’t any “NO-REFLECT” DREZ presets.
Are you using the ADV or the STD versions? The STD will get better performance.

Hi, I use the standard. Surely disabling them would help me a bit in terms of FPS.
Yeah I agree, turning it off in the parameters will not be as big a performance improvement as having a no reflect preset, I should probably make additional STD DREZ presets for the other variants (no reflect, glass, screen only) and probably add it for potato if it’s not there

I wouldn’t have thought to ask, you have enough on your plate as it is.

It would be great for those like me who still don’t have enough performing hardware. That would be a wonderful thing. If you could in the future I would be even more grateful. And anyway, thanks again for your work.
Those aren’t too much trouble, I just wish there was a way to control the resolution programmatically.
Maybe there would be a way to have a feature in the retroarch shaders system to override the resolution of the first pass, but still be driven from within the shader preset…

Like a DREZ parameter so the presets wouldn’t be needed anymore?

Yeah, wouldn’t that be a dream 
it would probably need to be something which could be applied in a simple preset. Certainly more flexible and not much maintenance cost. Although it touches the UI…

I don’t like the idea of losing part of my screen, I think i just need to find another shader preset were this issue will be fixed. Thanks for your answer by the way!

I’m not sure you will lose anything except the black bars on the top and bottom. (Which don’t belong anyway.)
Which core are you using? I’m not getting any black bars with Snes9x.
You can also change the aspect ratio. Here I have it set to 1.26.

Thanks for your quick response.
I never had any intention of using the regular Guest (filtering) settings which were added after v1.7.0 as my presets already used the NTSC Filtering settings.
I was hoping that I could rectify the slight softness increase after the update from v1.7.0 by using those same settings (probably just a slight tweak) based on my prior experience with them. However after the changes made in v1.8.0 and integration of the second Horizontal Filtering Section the NTSC Filtering settings stopped having any noticeable effect when adjusted in the same presets that it worked fine on before the update.
After every subsequent version of the shader that was released, I tried adjusting the NTSC Filtering settings first to see if I could get my preset back to how it was supposed to look, which is how it looks in v1.7.0 and nothing happened.
I also tested the new Horizontal Filtering Section that was added and nothing seemed to work until the most recent update to the Shader in v1.10.0.
No problem, I’ll test with the clean base preset and compare with standalone Guest -Advanced-NTSC next.
Thanks a lot for your patience and assistance.
Thanks, i didn’t know that i can choose shader aspect ration, i’m a newbie in those things you know. You solved my problem.

I’m glad you weren’t scared away from the Mega Bezel. There is a lot under the hood but once you have your brain wrapped around it, it provides glorious freedom.
If you have the time, make sure to read the README.md in the Mega_Bezel folder. It has a great breakdown of most of the parameters.
To view it offline you can use this awesome viewer.
