Perspective correction in GPU plugins

[BaD_BURN]

Is there any way PC (perspective correction) can be implemented in the PSX graphics plugins? I have MGS PC version but I'd rather play the PSX version because it has those cool motion blur effects, but still I can't help but notice and be annoyed by irregular textures/*whatever* that aren't all evenly displayed because of the lack of PC.

No it would not be possible because the psx has no z-buffer.

[FireGL]

play it on low resolution pre

The only way to do it would be High level emulation IIRC, and on the PSX that would require individual emus for pretty much every game you want to use.

Like i already answered if game uses standard library functions, they can be HLE-ed to support Z-coord generation, but no one did that and probably no one will do. Too much problems and no chance to get good compatibility.

Perspective correction:
Well it's a legitamate question the answer is there are several responses:

Simple One, No it's not possible with a GPU plugin. All the information provided to the GPU is already scaled and rotated and transformed, it just draws what it's given by the PSX emulator.

More Complicated:
It might be possible for a custom version of a PSX emulator to do so.
Nasty Textures:
Welcome to the PSX. PSX game do not use special textures that can be filtered for 'higher' resolution use Because the maximum resolution of ANY PSX game I've seen with 3d in it has always been 512 x 240 (Tomb Raider!). A special filter cannot be applied to the texture to make the texture scale properly at higher resolution. So things can be done but texture alignment is a pretty tricky problem with doing the filtering. IE the properly is the qualifyer.

A lot of people ask about the little vertical/horizontal lines in FF8/FF7 also. Well.. these are PSX Sprites (now that I'm using my brain properly these days) and are sent to the screen in there proper order (IE sorted be the game) nothing can be done to make them higher resolution either (really honest because of the alignment issues of the sprites on the screen filtering doesn't work the way you would like). There is only so much smoke and magic one can do with very low resolution textures.. Why am I mentioning this? WELL I'm glad you asked Because the same problem exists with all PSX textures, you can do some filtering but you have to be especially careful with repetitive textures.

The only way I can think of adding perspective correction to a GPU is merging the GTE with the GPU using a 'toggle' to attempt perspective correction or NOT. IT might be an interesting extension to PSX emulation to have GTE emulation added to the GPU. It's a complicate thing to try but would be definately interesting.

The textures are well heh.. not too much can be done unfortunately they can be scaled etc. but making them look as good as a much higher resolution PC version is not likely.
