Most of us aware of this, whats your point?
You want it implemented?

Something can be done, yet not as much as you seen to hope. The games are not coded to use it...

Addendum:Tessellation is older than it may seen, is been around since the ATI 8500 with the name of TruForm. Long ago an utility was made for Morrowind that was able to use it, the utility is named Morrowind Graphics Extender or MGE for short.

MGE was developed to provide DX9 functionality for the game and the result is impressive, yet it could make the game as much demanding as it's newer brother Oblivion, heavier actually at some places (like Balmora). Obviously TruForm was an optional feature and worked only for ATI cards and I don't know how it looked at all, but I never saw people hailing it that much, if I ever saw any comment about how it could enhance things.

Graphics enhancement over older games are common place, most are done over the games themselves and so, not meaningful to emulators. Others are done in a general fashion and this is the case where emulators can benefit totally (take as example the filtering, shading, resolution upscale and others). Tessellation possibly can be implemented under that limitation... still it is resources hungry and limited to DX11 cards, not the better thing to incentive the devs to face it when that much work is yet to be done to enhance performance and compatibility...

Let's PCSX2 team have the last word.

How exactly do you think this could be implemented? Tesselation can't do anything on it's own, it probably would have to be done on a per game basis if anything...

I tried TruForm in UT99/2K4, made it look worse.

As far as im aware, tessellation in emulation is completely useless as it requires far more control over the 3d being processed, generally it needs to be implemented in the 3d engine of the game, it's near on impossible to use as a post processing effect in an emulator.

Besides, with the quality of PS2 textures and models, it would probably make games look awful Tongue

yes, you're 100% right.
question about ps2 emulation:
why emulating win xp (aka virtualization, whatever) is very fast, but emulating game consoles are very slow/complex?
the truth is x companies force people to pay more & more for hardware.

windows xp was programmed for x86, which is native to your processor. emulating consoles is not native.

Imagine XP is an Englishman (lets say a senior), the PS2 is Chinese and Windows 7 (you) is an adult male.

If the Senior Englishman talks to you, you understand him easily and efficiently. If the Chineseman talks to you, you won't have a clue what he's on about, you will need a Translator (or emulator) to tell you what he's saying.

Even in this example, it's going to take you twice as long to have a conversation with the chinese man, the same is true for emulators globally. We read the PS2 language (which happens to be MIPS if you were curious) then the emulator says to your cpu "ok it means you want to do this" and then your cpu does it. It is this process that makes it slow.

For further information on why emulation is slower than native emulation, more specifically, PCSX2, have a read of this thread:
