Please bisect to the exact build that changed the behavior

Ok, it seems that the build is 4.0-8709 (D3D: Use a 32-bit floating point depth buffer.)

That build solves the fuzzy problem in the D3D backend, and it seems that the slow framerate when you go underwater stills in the previous builds, maybe the problem has been since always.

In short, the OpenGL backend works at more or less acceptable framerate, but with fuzzy water, and the D3D backend works ok before 4.0-8709, but this last backend goes at very very low fps at underwater since... ?? ever?

Can the 4.0-8709 be ported to OpenGL?

What's your GPU?

Ok, after many tests i can see where´s the problem:

The game runs at 60fps, but when you go underwater, it blocks at 30fps, and then, the game runs slow, at 50% of speed while you dive.

In D3D the game blocks at 30 fps, while in OpenGL runs at 60fps but fuzzy (first time runs at 30fps like the D3D, but after closing dolphin, runs at 60fps) I think because the shader cache of OpenGL works better than D3D.

Turn off EFB Copies to RAM. It uses a fullscreen EFB Copy effect, which is slow, and blurs the screen. It seems to be working correctly as far as I can tell. Turning on EFB Copies to Texture Only removes the blur.

Should this be added to the .ini of the game by default in a future release? "I ask from ignorance"

No, because I'm fairly certain it's supposed to be fuzzy underwater. I haven't imported the save to console yet, though.

Mmm... are you sure? in previous games of spyro the water is transparent and clear. And this looks like very very fuzzy. In D3D looks like the original game "I think".

I don't see how OpenGL could be doing it wrong with a more accurate depth buffer. I'll investigate more, I promise!

The answer is: They both are wrong! It's meant to be blurred, but only after a certain distance. D3D blurs the top half of the screen, OpenGL blurs the whole screen with no concern for distance. Software Renderer appears to be correct.

You have advance to me! I was looking for a youtube video, but i only found this from ps2 version (min 3:00)

The water looks clear as i can see like the D3D, but dunno, after all, i´m blind like a mole xD

Thanks for your help, JMC4789 : )

Btw, D3D blurs the top half of the screen only before 4.0-8709, after that build, the water looks very well.

That is not correct. I still see only the top half of the screen blurred.

Also, the water does indeed have a distance blur akin to that of Wind Waker. I played it on console on my capture card and verified this. No blur is wrong, so, EFB Copies to Texture is incorrect.

? Then why looks clear to me? maybe i have some non-default option enabled?

Do you have EFB Copies to Texture checked? I have no clue as to why it's still acting weird to me. I uploaded it to fifoci.

Umm, i see, ok then.

Normally i have it unchecked, but i tried to check and uncheck and no changes. The two backends stills the same.

D3D: 50% slow and clear.

OpenGL: 100% fast and fuzzy.

Maybe it's a difference between PAL and NTSC then; it's happened before :D

I looked at your screenshots, D3D is working correctly on your computer! That's awesome! It's slow due to EFB2RAM.

Enable or disable EFB2RAM isn´t a difference.

Oh, then I guess it isn't working. It's just the PAL game being slightly different with depth.

UPDATE: It seems that the new Directx12 backend solves most of this issue, the water looks clear, and 60fps too. But the background music is slow.
