No, it's doing it to make use of sli and crossfire top end GPU setups. The ones who usually complain about performance crank the settings max and expect their £100 6850 to max it out.
Martini1991 has spend shedloads on cards,so he is hardly one who is a budget card user. He has had the HD7970,HD7950,GTX680 and GTX660TI.
Poorly optimised means nothing about how good it looks.
Tessellation over a certain level does not necessarily make something look better,but it craters performanace for no reason. If you think tessellated underground oceans which you cannot see are great then waste your money. Look at even Crysis 1 - DX10 hardly improved it and yet under custom DX9 configs it was absolutely beautiful and much better looking than the menu settings.
But you know what?? The large open maps and great interactivity with objects really made Crysis believable. Its a game which I wanted to get a great card for and so did others.I spent the most on a card for Crysis. It was groundbreaking.
Even with custom higher resolution textures under DX11,Crysis 2 for me is still inferior to the first Crysis. Its flipping linear and so will be Crysis 3 as it has to be made with consoles in mind.
Tessellation was invented primarily for efficiency uses(before DX11 games hit this was being touted).
There are loads of other effects which are just as important and contribute to image quality. Just wasting it levels of massive tessellation levels which, makes no difference IMHO as they could be spent on other effects which make the game more believable. Its like having 64X AA at 2560x1600.
Textures would be one area,where more effort could be spent by Crytek on.
