Go into prescale.fx and find this:
sampler DiffuseSampler = sampler_state
{
Texture = <Diffuse>;
MipFilter = LINEAR;
MinFilter = LINEAR;
MagFilter = LINEAR;
That's why MAME's HLSL filter always looked like blurry dogshit. It was doing linear filtering on everything before you even got to adjusting the settings.
Just change it to this to get rid of the ---smurfy--- N64 filtering, and magically, HLSL will look sharp like a REAL arcade monitor, and you can actually use the defocus settings now to find the sweet spot between PC and arcade sharpness.
Texture = <Diffuse>;
MipFilter = NONE;
MinFilter = NONE;
MagFilter = NONE;
If you want to see before and after shots using the same settings, here you go.

See? NOT blurry crap anymore. Actually sharp. Like a real arcade monitor. Yeah. Yeaaah! Like an ACTUAL arcade monitor is crisp and sharp.

@bulbousbeard: can you pastebin or put your HLSL settings from mame.ini here for a test please?
-
Thank you!
I was trying to get hlsl shaders to make a high-resolution CRT (PC) monitor look like a PVM but gave up due to being unable to get rid of the blur.
I hope that this becomes the default.

Thanks for posting those. Why have you set your prescale so high at 8?
I was told 3 or 4 is good enough even at 1920X1080 display.

I run at 2560x1600 on one of my computers.

Hi bulbousbeard,
I'd say the average arcade monitor is somewhere between your "before" and "after" pictures. I find your results after the patch a bit too sharp, even if arcade monitors are not simply blurry as some pleople think: they do blend colors along the scanline to some extent.
This is my current HLSL setup (GM 0.149), notice the shades on Zandief legs, for instance:

PS: Note this runs at 30% on my system, so it's no where near being playable, it's just to show that normal hlsl is not necessarily blurry.
EDIT: Colors here are much brighter than on the picture, it seems the site converted it from .png to .jpg and the colors are screwed.

Thank You Calamity for sharing your settings ;D

To be fair I grabbed those settings somewhere ;)

What's missing in Calamity's screenshot, though, is the crispness of a real arcade monitor. It's impossible to get it with the linear filter.
The thing about this change is that it means you can actually use the defocus option now (you couldn't before because it would be way too blurry).
I agree about the sharpness. I had defocus on 0, and with no linearing filtering, it is a bit too sharp. If you set defocus at like 1.0 or 1.5, it's right in between. It still has the crispness of a CRT, but there's some bleed.
-
Here's what I'm talking about. Here are Calamity's HLSL settings with the modification and a defocus setting of 1.5.

See how you're still getting the subtle blur effect yet maintaining the crispness of the image?
The image will simply never be crisp with linear filtering applied to it first.
-
REALLY good tips on accurate HLSL setup.

Is HLSL applicable when used on a real 15khz arcade monitor, or is it something that's only applied on a modern monitor?
-
Very interesting I will have to give these a try.
-

This is by far the closest to an high-end arcade CRT in this thread. The ones in the beginning are too sharp, and the original Calamity ones are too soft - not sure what on earth was going on with your own "LINEAR" settings as those were atrocious.

hlsl was designed in mind to attempt to make the more modern types of monitors (eg. lcd) look more like a real (crt) arcade monitor

Hi Cools,
It's because the screenshot with the default prescale.fx had defocus 1.5 set. You basically can't use defocus at all with linear filtering, because you're getting double blurring.
By removing the linear filter, you can actually use the defocus setting to decide how blurry or sharp you want the image to be.

How do you achieve these results using SweetFX instead of HLSL?

Bulbousbeard,
Did the first post get edited? It looks to be missing some information.
Also what aperture.png are you using?
Thanks

What is it with emulator developers and blindness? None of them seem to know how a CRT is supposed to look.

Thanks! these changes make a huge difference.

This looks absolutely fantastic mate.
Can you confirm the HLSL settings you posted here (http://forum.arcadecontrols.com/index.php/topic,135470.msg1399350.html#msg1399350) reflect these screenshots ?
-
Boulataur since you're here, I have a couple of questions re SweetFX....has there been any changes/improvements to the CRT shader in the latest version of SWFX? Are we able to achieve scanline effects similar to MAME's HLSL effects, and what's been posted here in this thread? Has any further tweaks/settings ability been added? Will the new eFX injector bring anything new to the table related to the CRT shader?
Just curious
-
Thanks for this info, after doing some testing I'm still amazed at how good the HLSL settings looks on my LCD display. I have an AVGA and multi-sync arcade monitor in my cab for comparison and while this isn't as good, it's come a long way and is getting remarkably close. I never thought you'd be able to fully reproduce the arcade look on newer monitors but this is starting make me wonder. I'll bet if you put it behind a tinted glass it'd be even closer.
-
I spoke with MAMEdev today, and this change is going to be incorporated in the next version of MAME.

Sounds great, bulbousbeard. I still need to test this myself here.
