Start of a series of events that will put Nvidia into my good books, or calculated decision for publicity?

Windows Vista was updated to WDDM1.1 at the same time it got DirectX11, in the platform update:

http://en.wikipedia.org/wiki/Windows_Vista_Platform_Update#Platform_Update
Hmmm...

For example, even though DXGI 1.1 update introduces support for hardware 2D acceleration featured by WDDM 1.1 video drivers, only Direct2D and DirectWrite will employ it and GDI/GDI+ will continue to rely on software rendering.[citation needed] Also, even though Direct3D 11 runtime will be able to run on D3D9-class hardware and WDDM drivers using "feature levels" first introduced in Direct3D 10.1, Desktop Windows Manager has not been updated to use either Direct3D 10.1 or WARP software rasterizer

What's does a decent physx GPU run for now? If I could pick up a card for less that $50 I'd consider it.
The GT 240 is a good bet. Got mine on a Newegg shell shockers for less than $50. Has really low power consumption (40nm process) and no extra power connector needed. And with 96 shaders I have yet to see it use more than 50% GPU usage. If that is the case then even a lowly GT 220 would do (48 shaders).

LOL, sad I just recently sold my GT220 PPU which initially I bought to play BAA. I would’ve kept it if only I could’ve also used it as a CUDA dedicated card to enable the special filters in Just Cause 2.

I knew Nvidia was going to do this, I am not sure why this was a shocker. This is just another reason why I will still buy Nvidia products.

That quote about the Desktop Windows Manager not using DX10.1 is just about Aero. In Vista Aero uses DX9, in 7 Aero uses DX10.1 (or 9 via feature level support). All it's saying is that Vista still uses DX9 for Aero and was never updated to use 10.1.

It's not talking about game support or anything like that.

Finally they see sense. :rolleyes: If it's to get rid of old cards, then does that suggest they'll reintriduce the restriction in a later driver, all in the name of "Quality Assurance"??
You hit the nail on the head. There is no telling when they will re-activate this policy.

http://en.wikipedia.org/wiki/Windows_Vista_Platform_Update#Platform_Update
I couldn't get it to work on my son's machine with Vista Home Premium 32 bit. Trying to find the actual "platform update" in the myriad of updates at download.microsoft was impossible. The machine was fully updated via windows update but it still didn't work. Couldn't find the actual "platform update" even though the wikipedia article gives the date of the release.

Has anyone ACTUALLY got Vista to run with ATI and Nvidia drivers at the same time?

Let's hope they don't take that back later (say, after you buy a 9800gt) ;).
You definately need G92 8800gt or better for physX in games like Batman: AA and others. The Shellshocker right now is not good enough if that is what you might be looking at as 128bit memory cripples that card. :toast:

They won't because the cat is now out of the bag. Lets not let pessimism and paranoia infect the thread. We have no reason to think they would be ok with commiting reputation suicide by revoking it. It would mess up marketing campaigns and things that are similar in the retail segment. The only "what if" is will they enable its acceleration on ATi GPUs. It would work as well and there is no denying that, but it could still work.

But at least we know it's breakable if they do go back to "blocking" out ATI.

I'll keep my eye on this, if nVidia is seriously going to allow their cards to be used as PPUs I will buy a new card for PhysX. One of the 200 series. I'm using an 8800GT at the moment.

cool.... now i can slap in my 8600GT and... uhh.. well actually i have no games that use PhysX, lol. might aquire metro 2033 just for this.
Well, if you have Core i7, you don't even need HW PhysX, I tried it with enabled Advanced PhysX and it worked pretty well on CPU itself. Maybe slight slowdown but still pretty much playable. Opposed to Mirror's Edge where it will lag like insane with Advanced PhysX with only one physics affected object moving around. Heh.

Yeah man they are like evil incarnate and eat babies. Seriously, real babies. They aren't even dead yet when they start eating them. A comic book villian runs Nvidia and he will never stop until the whole world hates him.

OR

Nvidia operates like any other business and profit is their only concern. AMD, Intel, and Nvidia all answer to stock holders. AMD is not the Messiah, and Nvidia is not run by Satan.

:wtf: cause i ever made that claim right? Im simply saying it would not surprise me at all if maybe 3 months from now Nvidia decides to off this in a driver update....you know kinda like they did in the past? Or are we just choosing to ignore that? :rolleyes:

WTF has physx got to offer apart from some crappy effects that have no effect on gameplay whatsoever, very limited support in games " current and in the future " with the majority being complete balls, oh yeah expect 50% drop in FPS with phsyx hardware accelerated games. Havok FTW.:rockout:

to late because the amount of games that use physx is limited and the popularity it had has dropped, they kinda dropped it when people where buying second cards for physx

to me its a waste of say £20-£40

but nice gesture if you have one lying around

I am just tired of the cartoon-like paranoia. People circumvented it and that is why they just opened it up and left it for all to use IMO. You know they did a while back and now the two reasons they were holding back are gone. The other reason was a lack of high end offerings to combat ATi in the time gap before release thanks to fab issues. They also desperately need to move G92 derivatives and the best way to do so is SLI support and/or PhysX friendly cards. You don't remove support unless you have a damn good reason because it is a business.
