微软澄清DX10.1不支持DX10硬件的传闻
买了8800/2900卡的朋友不用担心了。最新消息是DX10.1不会排斥目前的显卡，DX10.1只是小小的改进，可能会有小细节不为当前的显卡支持。（可以看下面的英文原文）。
顺便为买了8800/2900卡的人辩解一下，我自己就买了。如果一定要说每个新DX标准出来，要第2代卡才更好的话，我没有意见。但是如果都想着这样的话，最有性价比的就是像现在的7900/1950停产的时候。等下一代9200之类的，那绝对不会比现在的8800GTX便宜，而且我相信9200的中端肯定不如8800GTX。等到DX9游戏淘汰，9200的卡变白菜价，那又有5000元的10000+卡和DX11？所以不用为买了8800/2900后悔，真的要后悔的，是买了85/86/26....的人。
Microsoft's Sam Glassenberg told Next-Gen in a phone interview, "DX10.1 fully supports DX10 hardware. No hardware support is being removed....It's strictly a superset. It's basically an update to DX10 that extends the hardware functionality slightly."
He said that the update is similar to what Microsoft did with DX9. "We did make updates to [DX9] that extended the supported feature set.
"All the hardware is still supported, all the games still run, all the features are still there, we've just simply extended the feature set and the lifetime of the API," he said...
Glassenberg conceded that "There will be new features [with DX10.1], and those features may be exposed on new hardware, but this is similar to the model that we had with DX9...[except] with DX10.1, we're saying [to developers], 'if you want to support the new features, you have to support all of them [including original DX10 features].'"...
Even though DX10.1 will support current DX10 graphics hardware, today's DX10 hardware will not be able to support all of the features of DX10.1, which includes incremental improvements to 3D rendering quality....
Glassenberg also addressed rumors that DX10--currently exclusive to Vista--would be coming to Microsoft's Windows XP. It seems that DX10's Vista exclusivity is unlikely to change.
