A little more of spline36 shader and some improve.

[ferion11]

The #3921 is OK! Thanks for the work.

But you said on 7d8aed0: "Spline36 isn't as amazing as I had hoped heh". Then i have to test this.

It's hard to me put this in words, then I will show the images. I'm using the ppsspp-v0.9.1-2097-g62685b6-windows-x86 (and my video card is nvidia)

The game this time is PSP Final Fantasy VII Crisis Core and 3x resolution (480x272 to 1440x816):

• Using the RemoteJoyLite-fix, spline36:

It' a very beautiful result, at least on the RemoteJoyLite-fix. Let's see this on the ppsspp-v0.9.1-2097-g62685b6-windows-x86:

• Using ppsspp-v0.9.1-2097-g62685b6-windows-x86, raw (default options):

It's not so good fragment shader like on the code.google.com/p/remote-joy-lite-fix/ project. I'm not making the comparative of Vertex shader or the internal resolution now. Just the filter on the upscaling.

By the way, some more things:

• The ppsspp-v0.9.1-2097-g62685b6-windows-x86 using 6x internal resolution:

• The ppsspp-v0.9.1-2097-g62685b6-windows-x86 using 6x internal resolution and spline36 shader:

It seems to me that the internal resolution reduced. Maybe it's my imagination.

• And the ppsspp-v0.9.1-2097-g62685b6-windows-x86 using 6x internal resolution and texture scaling "3x xBRZ":

I want some like this. But NOT with the texture scaling "3x xBRZ", and yes with the same result the spline36 shader do on the RemoteJoyLite-fix on the second image.

And thanks again for the good job ^^

Well you won't get the nice spline effect on the text if you set Render Resolution to higher than 1x, because then the text will first be upscaled as it is rendered with an ugly method (nearest) and then that result gets spline-scaled. Not much point. When using Spline36, you really want to render at 1x. Then you should get exactly the same result as RemoteJoy.

[hrydgard]

That said, that last one with texture scaling too looks pretty good :)

[ferion11]

Are you sure that we can not have this result I expect? Case the remotelite-joy receives only the pure image from the PSP buffer. All game graphical processing is done in the PSP. I just want to apply this filter in the final image.

[hrydgard]

Could have something similar if you make a spline texture scaler...

[ferion11]

Can I ask for this? I mean, I'm very hapy with the last result, and I'm worried if I'm asking too much ^^

[hrydgard]

I think you can get really close already by choosing "Bicubic" texture scaling, 3x or 4x. That's also a spline, maybe it's a 4x4 spline rather than a 6x6 but i think it looks ok :)

[ferion11]

Oh! Thanks! I will try this ^^

[ferion11]

That option is very good. But the "Bicubic" texture scaling let a lot of artifacts behind (lines and other), look:

And I want this running on all the final image, the "Bicubic" texture scaling is not helping the movies parts on the emu.

Maybe one option for replace the first upscale "nearest" method with some better (or none, maybe), will make the fragment shader have the same result. After all, the font, the movies and all is just part of one big image for the remotelite-joy, and it work well.

[hrydgard]

Well, I can't do magic. If you set PPSSPP to 1x rendering you will get the same nice effect but you pay for it with the low resolution :)

I'll close this now, as I'm not sure there's anything that can be easily done.
