should i cancel my order for the 480 i was gonna add for physix?

I think its just so ATi owners can buy nvidia cards and boost their profits then they disable it again

+1

This was my first thought. They allow it now, but they can disable it again later. It's just the sort of thing I'd expect.

Edit: I see it was a bug. What a non-surprise.

You not got the original cooler in a box in the loft somewhere?

I do but it had some weird heat conducting pads that sat between the vram chips and the heat sink that are now all dried up and dirty

Oh, so it was a bug? D:

From the NV blog.

While it was not intentional, due to the overwhelming positive response to the beta driver we have decided to leave the beta up with support enabled.

It would have been mirrored on so many sites by now that removing it would be irrelevant if they removed it or not anyway.

dmxdex2020 · 29 May 2010 at 16:42

So people can now use physix with an ati card. Just get the beta drivers.

Rroff · 29 May 2010 at 16:44

Therefore our WHQL certified drivers will continue to have this support disabled.

Wonder if theres any real substance to the veiled reference to beta drivers not having it disabled :S

It would give them back a lot of goodwill they seem to have lost recently.

hope so - as doing some cuda stuff atm would like to do on main machine not laptop(only machine i own with nvidia atm)

Boozebeard · 29 May 2010 at 23:31

So how do i get this to work? I plugged in my 9800 in and installed those beta drivers, do I have to enable something?

I have batman, how do I know if its working?

Asus smart doctor wont work anymore, "Can not find graphics card information."

Rroff · 29 May 2010 at 23:46

Should have the option to enable GPU PhysX on high in Batman configuration, to check if its working run the benchmark ingame - if it is you will have flappy flags hanging from the girders in the first room, steam swirling around the guard walking through the checkpoint below and fog flowing along the floor in the cave section.

Ok, just downloadin it from steam D:

I turned the option on in batman but it said "your hardware does not support Physx performance will be severly reduced" does that mean it's not working? D:

Didn't have the flags and the performance was awfull. Do I need to enable something in the nvidia control panel? I can't find anything about physx.

mm, ok. I got it to work buy plugging my second monitor into the nvidia card.
So it's working apart from not being able to get smart doctor to load. Doesn't seem to be anyway to get smart doctor to work with a nvidia card in

It all works fine but I can't find a way to make smart doctor work. Will probably have to take it out as I can't get much of an OC on my card without the voltage tweak.

God I hate smart doctor. I wish I had bought a reference card instead of this stupid direct cu one, would have been cheaper too.

For reference using the built in benchmark in batman AA I get 33/92/64 fps min/max/avg

That's 1920x1200, everything on max, physx on high and 4xAA forced in the ATI control panel (I couldnt guarantee the AA worked)

Edit:Just tried it again with AA off and I get 68 average so I guess it was on

Time to dig out my old 8800GTS 320MB

AA doesn't seem to have a huge impact on the average framerate in Batman - just pulls down the max and minimum fps a bit but somehow the average is mostly unaffected.

Use MSI. I find Asus smartdoctor really buggy and can acheive a higher stable overclock using MSI.

Also if you set up your Nvidia on an extended desktop you don't need to plug anything into your card.

The average is worked out from the Min - Max.

MSI can only controll the voltage for reference cards or custom MSI PCB's. I've got the asus direct cu card so smart doctor is all I can use

If someone from asus reads this please fix smart doctor to work with a secondary nvidia card plugged in

Depends how its calculated... I don't think it just does an average of the min and max tho might be wrong - but testing higher AA modes I was getting same average give or take a couple of fps even with massive min/max fps hits.

Your getting duff results. Ignore them.
