This is not the first time when a major game developer indicates lukewarm attitude towards DirectX 10. Earlier this year John Carmack of id Software said he would not "jump" on the DirectX 10 hardware immediately. Other game developers are also not leapfrogging to DirectX 10 mainly because two most advanced game consoles available today – Microsoft Xbox 360 and Sony PlayStation 3 – are equipped with graphics chips which feature-set resembles that of DirectX 9 shader model 3.0, therefore, it is easier to develop new titles with similar graphics features in mind.
“Right now with the flexibility of DX9, we can take advantage of DX10 hardware functionality through DX9. For example, the tesselator in ATI’s [Radeon HD 2000] hardware is super valuable and we can get to it through DX9, so that’s probably a better investment than going after a DX10 API,” Mr. Newell added.
