Ahem, 32 cars, rain, max settings, CPU vs GPU physX:
3 runs for both CPU and GPU physX to minimize the variance between runs.
And here's the worst case scenario run that I ran 6 times in total:

Right at the start of a race with all the cars on the screen and lots of water effects everywhere because of it. Also the player car visible so you have to render the water effects for that as well including all the rain drops on the car.
(also excuse the keyboard driving)
Has AMD even made an official statement?
Only that they work on a new driver to fix the performance issues.
I installed this game last night and with all the default setting it was playable.
I then tried on high and still playable this is with rain off.
I'm going to try it again tonight and try to create some of the benchmarks in this thread.
i'm really curious to see what happens on my hybrid rig.
Only that they work on a new driver to fix the performance issues.
How is the Hybrid scene going? I haven't touched it since I went full Nvidia, but if I get a 390X I'd dabble back as I got a spare GTX 680 I can go hybrid with.
Hybrid still works great with 4/5/6 series cards there is extra work required for 7 series cards as the person that made this hack no longer updates it.
As long as you stick to 314.22 drivers newer drives NV has a block in it to prevent this hack.
There are nVidia centric optimizations in play and doesn't desire to incur the resources to support and Q/A competitors hardware and software, from my understanding.
Why did they block it?
PhysXInfo.com: What do you think about Hybrid PhysX? Isnt it for good?
Rev Lebaredian: Good at what cost?
Supporting it would be a huge amount of QA for us, and it would be weird too if well find a bug in AMDs drivers, what will we do?
Ashu Rege: For the foreseeable future we will not supporting it officially. If it works- it works, if some guys can figure out how to make it work great for them.
nvidia said: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.
Why is it "downright pathetic"? People seem to have enough problems with two display drivers being installed at the same time, even if the card isn't installed. Look at how many people suggest using DDU when switching vendors, just to make sure there are no remnants.
And now you suggest they should figure out how to make them work together? What happens when AMD releases a new driver and it breaks everything? Should Nvidia have to put man hours into getting it working again?

My view: would like to see nVidia rethink this and invest in support and Q/A, thought it was a bit short sided for the potential of PhysX adoption.
Or just not block it and still not support it. Just have a policy of use at your own risk. Let AMD worry about optimizing their driver if they want their customers to be able to use it.

I think people are somewhat annoyed because all NV would have to do is say its not supported,without having to put the driver block in. Leave it open like how it was prior to the block.
So users like myself could just use it at our own risk because we understand there is no support for it.
The driver block is considered a dick move!
If any novice users decided to call just drop the not supported line on them call is done. Doesn't require any support or money to be spent by NV.
P10 "There is no reason for a changelog as all development on this mod is now officially frozen/completed. They have defeated my hack at this point, it's too difficult/I am too busy to continue, but it was good while it lasted. My recommendation is that if Mantle isn't awesome(both revolutionary and worth more than PhysX, which I doubt --does anybody know yet?) then just buy nVidia next time I guess(They only rip you off with the top of the line cards.)"
Basically this. My recollection was WDDM 1.3/DERP 2.0 launched and people were using GeForce with AMD cards. And PhysX was working, but quickly got removed as it not being functional. Nvidia started saying it wasn't compatible.
Then they accidentally forgot to turn off whatever flag was in the driver with a beta driver and magically PhysX worked again without issue with an AMD card. Then it was revealed it was blocked.
And it doesn't end there, because that was enough of a bad choice Nvidia went further and put other flags that would intentionally create issues if an AMD card was found that they then pointed fingers at saying it was incompatible. But some smart people found they were bogus flags, removed them and magically PhysX worked again with AMD cards.
I really wonder how it will be with WDDM 1.2. I'm pretty sure Nvidia has managed to fully block an AMD card at this point since it seems an older version of a driver is required.
EDIT: Guy who was doing the mod his final words:
Seems they just kept blocking it.
