DirectX 10

Games are not going to suddenly switch over to DX10 period, it will take several months for games to start making use of it - and that's only scratching the surface. They certainly wont be dropping support for DX9, why would they? they'd cut off 95% of their market.
 
Direct X 10 wont be released untill Vista is released, Vista`s earliest release date is December, (and thats still a floating date...)

you wont need to worry about DX 10 for AT LEAST a year, think about it... your a games manufacturer, the DX 10 development tools arnt even available for use yet so your gonna use dx9.0c, and even if they were and games developers started to build a game today, your still looking at 14 months build time at least,

you wont need to worry about dx 10 for some time, if i were you, i would ignore the issue for now.

as for backwards compatabillity, dx 10 will support previous Versions of DX but through a software layer which could cause performance degradation when compared to playing the game in 9.0C

for more information, see the following...


http://www.theinquirer.net/?article=21077 <--- DX 10 info,


possible earliest vista release date is dec 7th.

Depends if the G80 is optimized for DX10. Can you remember what happened with the GF2 Ultra and GF3. They went from fixed to programmable T&L. The GF2 Ultra was faster than the GF3 in most games at the time. It took the GF4 to make the leap in performance and developers to take advantage of the new tech. The G80's unified approach might actually be slower with current games. The next gen will certainly be a leap but how many people will still have the old tech?? It certainly will be interesting

Agreeed, but Nvidia are trying to keep clear of the unified archiytecture approach precisely for that reason in that it will likely slow thins down- dedicated harwdare is always faster and cheaper,

I am not saying games wont work if you have DX9, I'm saying if you want to stay in tune and want the latest games running at high. etc then you will obviously need Windows Vista and a gfx card with DX10 aight'!

Obviously :o

Let me guess, you read the little article in CPC about Microsoft and Bungie only using Vista on Halo 2. I think the words 'Monopoly' and 'Under the thumb' comes to mind.

Why worry now about what your going need in over a year or more time :confused:

Wrong - the main reason the Ultra was similar was its clock speeds. The G80 will be better at DX9 and 10 respectively, to say it won't is plain wrong. Aslong as the G80 has good clock speeds then it will stomp at DX9 and probably 10, the same goes for the R600 as well.

Why am I wrong? Do you know something I don't? You are just plain wrong to state it will when you have no idea either way ;)

G80+Vista+DX10 a lot of things in the cooking pot. I don't know really anything about the R600 but I have heard a few things about the G80 and there seems to be a few compromises.

I disagree - from memory the ultra was stomping the GF3 at most games and it was mainly due to the Fixed T&L. I can remember seeing graphs showing performace at the same clock and the ultra was more effiecient.

Who says the G80 will have high clock speed?
Nvidia prefers the wide architecture, high IPC, low clock rate approach.

Well, NV want to keep away from a unified architecture for as long as possible because of the compromises. ATI are keen to move to unified ASAP.

It will be interesting to see which appraoch works best. Unified has a lot of extra transistors and is only as fast as the load balancing algorithm. A lot of valueable real-estate will be spent making the R600 unified, but there should be a lot of efficiency once up and running.

NV's G80 if it is non-unified as most rumours indicate then it will have a higher raw performance but will be less efficient.

Hence I said ASLONG AS. Blimey, it's quite simple. The clock speeds where what gave the Ultra the edge. ASLONG AS the G80 has good clock speeds it WILL be quicker. By definition DX10 does DX9 stuff in a much more efficient way, hence will be quicker.

Oh and factor in driver peformance - one of the things which made the ultra good competition is that it had mature drivers, but once the Geforce 3's drivers caught up all was well.
