Tesselation, it seems to be everybody's favourite new word, but what implications does it have? I expect that we'll be hearing more and more about tesselation over coming months. This can in part be attributed to Fermi's superior tesselation performance: Nvidia, if and when they finally get sufficient stocks of 480's and 470's on to shop shelves, will undoubtedly put a lot of effort into spinning an area where they have a clear advantage. However, will this translate into an increased number of games that make use of this capacity? Can we expect to see more and more titles that are optimised to take advantage of one of Fermi's strongest selling points? Will such optimisation take place on a level playing field, or can we expect to see something along the lines of the disabled in-game AA for Ati cards present in the Arkham Asylum title? To take Metro 2033 as an example, a TWIMTBP game, the increased tesselation capacity of the 480 isn't really showing much in game advantage. I have no doubt that Southern Islands will improve tesselation capacity; however, whether that is simply to take the title away from Nvidia or whether we, as consumers, will see a tangible improvement in the near future remains to be seen. More importantly, should anyone considering upgrading to a 5850 or a 5870 be concerned about the tesselation performance of either card? Is Fermi that much better and does it matter?
