M$ has basically said stiff luck to anyone who has purchased DX10 cards. They can not be firmware updated or anything else can't be done to them to support the new standard. This has been confirmed by multiple geek sites and you can Google them yourself.
DX10.1 cards will be the new standard shortly and any DX10.1 games will be specific to those cards for any added enhancements; however that is not to say these games will not be playable on DX10 cards. I believe the game vendors will be very mindful of this and opt to just have them be DX10 compatible. I really wouldn't worry too much about it as I don't feel it's a big red herring for the industry.
It does show however the contempt and frivolous ties M$ has towards its hardware partners and 3rd party gaming developers. Any wonder why vendors dragged their backsides in creating drivers for the all new wizbang Vista
As i mentioned earlier i wouldn't bother too much with it as I am not . This written by the owner of 2 nvidia 8800 gts cards in SLi mode.
i read your update for Vista SP1.
With the advent of directX 10.1, does it mean that my current GeForce 8600 GT card will have to be replaced in favor of a new card that will handle 10.1? I have been assuming that there would be a driver update available when the time comes that would include the ability to run directX 10.1. But, will there actually be a need for a hardware update instead? I really want to get that question resolved once and for all.
Thanks in advance.
