DirectX 10.1

I have recently got a pc with built-in ATI Radeon 4650 HD 1GB DDR2 which I think supports DX10.1

In DxDiag it only says DirectX 10, does this mean I only have DX10, and if I do how do I upgrade to DX10.1

I'm at Service Pack 1

If he can find a game that has uses it

^ unless you stick at drivers below 186.

^ well CUDA can be ported to ATi cards so it's possible that if someone with a lot of $ and a highly skilled team behind them, we could get CUDA and therefore PhysX on ATi GPU's.

Well im running an ATI card and downloaded a demo yesterday which installed Physx, so why did it bother if i cant use it ? Cryostasis uses it as well i beleive ?

Mactronix

If youre using the ATI card as the primary, and a nVidia card as secondary, from the new drivers onwards, physx wont work, its SW blocked from nVidia

You may not be able to use it, but itll be there in case you ever remove all your ATI cards, and use only nVidia

"Well for all those who have have used Nvidia cards for PhysX and ATI cards to render graphics in Windows 7...All that is about to change.

Since the release of 186 graphics drivers Nvidia has decided to disable PhysX anytime a Non-Nvidia GPU is even present in the same PC. Nvidia again has shot themselves in the foot here and showed they are not customer oriented. Since they are pushing Physx this will not win over any ATI fanboys with this latest decision.

Here is a copy of the email I received from Nvidia support confirming what they have done.

"Hello JC,

Ill explain why this function was disabled.

Physx is an open software standard any company can freely develop hardware or software that supports it. Nvidia supports GPU accelerated Physx on NVIDIA GPUs while using NVIDIA GPUs for graphics. NVIDIA performs extensive Engineering, Development, and QA work that makes Physx a great experience for customers. For a variety of reasons - some development expense some quality assurance and some business reasons NVIDIA will not support GPU accelerated Physx with NVIDIA GPUs while GPU rendering is happening on non- NVIDIA GPUs. I'm sorry for any inconvenience caused but I hope you can understand.

Best Regards,
Troy
NVIDIA Customer Care"

So this really confirms that PhysX will be doomed as an adopted API regardless how hard Nvidia pushes it as a result of action like this."

Its no longer available to ATI cards, period

Think about it. If physx wasnt proprietary, this couldnt have been done to begin with. Thats the problem.

I just dont understamd. Why should 1 company cow tow to another? This was doing fine until nVidia decided to cut it off, and its also being done with ageia cards too.
To act like its ATIs inability to do it, when they never asked, or to remove it, when ATI never asked, Id think youd have to ask nVidia as to why they cut it off, before assuming another company adopt an obviously proprietary thing.
Theres nothing from nVidia to do the same thing if ATI did such an adoption, similar to what we see with people having the ageia ppus and using ATI cards.

once dx11 go mainstream, is it safe to assume that sm 4.0-4.1-5.0 are the only options available? or we'd still see the benevolent sm3.0?

Nivida just pissed me off,, they are wet farts to me now. I got an Ageia card for the mix and match possabilities, now it is all lost.

You mentioned a designer of gpu's and you weren't referring to gpu accleration?

Seriously now.

1+^ ahhhh, the power of streaming....

Don't play dumb.

Nvidia are poo poo heads

Let them get on with it i say i heard a whisper that LRB is coming along very nicley thank you, lets see where Nvidia are when ATI/AMD and Intel/MS start working together and leave then in the roadside.

^ it's larrabee, and no-one really knows when it'll be released.

Can't wait for Intel to take nvidia out of the market, then we'll have only two company's to worry about in the CPU and GPU market.

larrabee!! thankyou lol.

the article about larrabee was a bit of umm, intense reading but what i remember was that it will be based on a pentium dualcore arcitecture. should prove interesting... i hope that nvidia gets kicked out of the market as well, they seem to be going the way of the dinosaur...
(WOOHOO!!)

We shouldnt want nVidia kicked out, because in the long run, itll only hurt ATI.
Intel has massive amounts of monies to throw at R&D, even to the point of supporting a lower perf product, underselling it, and using its influence to alter the approach of PC gaming as we know it using the DX and opengl standards.
nVidia has alot of influence, and tho theyve already done this non standardized approach thru physx , they are just as reliant upon DX and opengl as ATI is.
The fact that the 2 , ATI and nVidia both hold to these standards will help insure future developement along these lines of standardisation, and make LRB, which is a very flexable jack of all trades and master of none type of component also adhere to those standards.
Architecturally, and with all of Intels backing, money, R&D etc, a radical change too quickly would have negative effects on both ATI and nVidia, and LRB would stand unopposed
