link: Microsoft presents Direct3D 10.1 at SIGGRAPH

So just in case you're about to shell out tons of dough on a long term DX10 video card solution, you may want to be aware of this. I think it's swaying me to wait until the 9 series to buy a new high end card.

Direct3D 10.1 looks to be quite a significant release for DirectX. Some of the interesting points to note:

* Will require Windows Vista SP1 * Not “supported” by current-generation DX10 hardware * “Extension” to Direct3D 10 - “complete” D3D10 * 5 new API * Improves rendering quality o Enforces floating point 32 rendering o Enforces 4x multi-sample anti-aliasing (MSAA)

For argument’s sake, Direct3D 10.1 didn’t come out of the blue. Microsoft had always planned for a 10.1 update when they released version 10. However that is no excuse as to why is it not compatible with DX10 hardware? People who have to dish out hundreds of premium dollars to buy DirectX-10 hardware today will be outdated in less than 6 months.

To be fair, both ATI and Nvidia disclosed the dx10.0 only support with their 1st generation dx10 cards over a year ago, but I think it's not very well known.

Honestly, this sucks. Then again, MS is hunting for money.

perhaps they did release it. But honestly, most people will see DX10 support as, well anything labled with DX10 as being supported.

This makes me wary of updates now, does every incremental update of directx mean the hardware supporting the last revision will no longer be supported? If so, that's the biggest waste of time and money for both consumers and card makers. No one will ever buy the more expensive cards again if this is true.

WTF? This isn't exactly a new phenomenon...

Software hooks are created. GPU companies manfacture GPUs that can access and make use of those hooks. Software hooks are updates. Existing GPUs don't support the new hooks.

Nothing substantial has changed. Anyone who is surprised by this has had their head in the sand. Development cycles are speeding up, but that's nothing new, either.

Would anyone cry foul if Vista's first service pack shipped with DX11?

True, but the problem is that this is an incremental update. Users spent hundreds if not thousands making a new DX10 ready system only to find out it'll be obsolete with the first revision to DX10.

DX11 would be different. As history with DirectX has shown, the major updates require changes in hardware and having it be DX11 would merit it.. but DX10.1? That's like creating a service pack for windows saying everything released compatible with windows no longer works and you'll need completely new hardware. To a gamer there is no difference as both are a necessity to play games properly.

That's the point I was trying to make as well. I fully expect this with a major release, but the first DX update already being unsupported seems a little unusual to me. It's like they're saying , "oh by the way, the 1st gen gpu's were only beta DX10 cards, here comes version 1.0 for the rest of you".

yeah I understand.

I'm also a little frustrated because I bought 2 8800gtx's only to find out their lifespan has now been set to a scale well before I wanted.

I'd imagine this is because cards are now required to support all the functions of a given DX release rather than being queried by the rest of the computer all the time. Either way I don't see programmers developing for 10.1 for quite a while, there are hardly any games that require DX10 since so few people see it as needed or supported. The hardware just isn't there and probably won't be for a long time to make programming for 10.1 a good idea. Should see a price dip in the cards out at the moment though.
