DH Interview with John Byrne, AMD VP of World Wide GPU and Chipsets
 

I recently had some time to sit with John Byrne in AMD and quizzed him on a variety of subjects.

*Driver Heaven:* Up until now most DX10 games were actually DX9 games with extra DX10 effects. Do you think your architecture will give you an edge once fully DX10 games start coming out?

*John: *We’re very confident in our architecture. Most of the DX10 games we’ve seen so far have been rather straightforward ports of DX9 code – and that process is fraught with difficulties. If the code was originally written with DX9 in mind then it often doesn’t translate well to DX10 – and for that reason quite a few games seem to have lackluster performance. We’re gradually seeing a trend to “true” DX10 coding – and when that happens it brings huge benefits. The Acid test seems to be simple. If, at the same settings, the DX10 game runs slower – then in most cases you should stick with the DX9 version. But if, at those same settings, the DX10 version is fastest – then you’re probably looking at a great and new piece of coding. As we go forward, we certainly expect more and more games to have a native DX10 code-path – and that’s great news for us. It gives gamers a much better experience – and really lets DX10 hardware like the RV670 shine! That’s when you’ll see why our DX10 hardware was the right choice…!
