Would you find it acceptable if AMD assisted a game dev to make a demo that purposely used a code path that crippled performance on Nvidia hardware, and then asked reviewers to include it as part of their benchmark suite? Also, any offer Nvidia made to the dev to help improve performance would be denied.
All good?
Okay, I see that in your head it is already decided that nVidia has deliberately crippled performance on AMD's hardware.
Apparently in your head there is no possibility that AMD's hardware might actually perform considerably worse regarding certain aspects of the DX11 standard.
As long as you are not doing anything nasty, I have no problems with making benchmarks and games that show off the latest features on new hardware.
I fully supported ATi with their Radeon 9700, and 3DMark03, Half-Life 2 and various other games, which pushed SM2.0, making GeForce FX look like the underpowered piece of you-know-what that it really was.
Nothing wrong with that. As soon as nVidia came out with the GeForce 6-series, their SM2.0 was up to snuff, and all those benchmarks and games worked fine as well, because there was nothing nasty about them, no crippling nVidia.
