We'd have expected the game engine to include a simple optimization that would set a boundary for the water at or near the coastline, so the GPU isn't doing this tessellation work unnecessarily.' Obviously, that's quite a bit needless of GPU geometry processing load. That's true here, and we've found that it's also the case in other outdoor areas of the game with a coastline nearby. The GPU is doing the work of creating the mesh, despite the fact that the water will be completely occluded by other objects in the final, rendered frame. The tessellated water mesh remains in the scene, apparently ebbing and flowing beneath the land throughout, even though it's not visible. Here's what TechReport's Scott Wasson had to say about it at the time. Huddy is referring to the over-tessellation that was discovered by in Crysis 2 a few years ago.В Where invisible bodies of water and blocks of concrete were needlessly subjected to huge amounts of tessellation that did not contribute to the visual quality of the game but negatively impacted performance. And if you look at Crysis 2 in particular, you see that theyвЂ™re tessellating water thatвЂ™s not visible to millions of triangles every frame, and theyвЂ™re tessellating blocks of concrete вЂ“ essentially large rectangular objects вЂ“ and generating millions of triangles per frame which are useless.' But the consequence of it is it brings PCs to their knees when itвЂ™s unnecessary. 'ThatвЂ™s the consequence of it, whether itвЂ™s intended or not - and I guess I canвЂ™t read anyoneвЂ™s minds so I canвЂ™t tell you what their intention is. ItВ certainly feels like itвЂ™s about reducing the performance, even on high-end graphics cards, so that people have to buy something new.

'Number one: Nvidia Gameworks typically damages the performance on Nvidia hardware as well, which is a bit tragic really. But I think itвЂ™s more negative than that вЂ“ and IвЂ™ll point to two facts here,' 'If it was just that, then people could say: IвЂ™ll take my choice and turn it off if IвЂ™m with AMD and leave it on if IвЂ™m with Nvidia. Going back toВ the issueВ of the day, when asked about Nvidia's GameWorks program Huddy had this to say : Huddy, AMD's Chief Gaming Scientist, had more than a few things to say about the program from the competition.ДЇour days ago we published an exclusive four thousand word report about the situation with Nvidia's GameWorks program and many of its intricacies that covers both the Nvidia and AMD sides of the story whichВ you should definitely go read before you proceed.

Yesterday AMD's Richard Huddy went on the offensive in an interview with PCR.
