Oh dear Nvidia's share price has already taken a hell of a beating

Yeah, but barely anyone uses CryEngine and Crytek still needs to show this live. It is very interesting tech, but Crytek still needs to prove themselves.

I can't remember the last game I played with CryEngine, aside from Kingdom Come: Deliverance.

Wish it was downloadable, Wouldn't mind trying it on my Radeon VII.

Yes! I'd love to see this in action.

D'you know what? I've kinda had this feeling since RT came along that somehow AMD's big fat heater cards would be able to do it somehow. Kinda by throwing brawn at it.

It would also not be the first time that Nvidia have tried to monopolise a technology by coming up with a small lump of hardware that you must have to be able to run something (G-Sync for example).

Like I said ages ago RT will only happen when it's for all, not just a tiny % of half of the market (I don't mean half by actual user figures I mean half as in AMD and Nvidia, two halves make a whole and all that s**t).

That's exactly why Microsoft have just made DX12 work in Windows 7, because they want every one to code for DX12 (probably more importantly for their future consoles).

It could only take one meaty game like Crysis 4 to turn this whole shenanigans on its head.

The last part of what you said in the article is very telling, IMO. This bit...

Crytek has also stated that the technique will be optimised for the latest graphics cards and supported APIs like Vulkan and DirectX 12.

Or in other words "Pascal's gonna suck". God, it's almost like Nvidia knew all of this and rushed out their RTX cards before it happened. And yes, that's proper titty licking tinfoil hat stuff there but it does seem mighty odd ! I can just see Nvidia in the boardroom now...

"Quick ! RT is about to become a thing let's quickly get out a tech unique to us before AMD can come up with anything !"

Every graphics can do real time Ray tracing, some better than others. Rtx just has hardware dedicated to it. It was and is just a matter of optimisation of the software. It's no different for any in game effect look at physx, u needed to buy an agiea card at first but then bang, nvidia added it to their gpus as a software overhead, remember it used to drop fps massively, not anymore its a standard (if outdated) feature for their cards

Yeah Microsoft said they started open fine tuning of the DXR API between hardware vendors and game engine developers in around Spring 2017 while work on Turing's RT implementation started a couple of years prior of course hardware of this scale takes around 18 months just to go from final designs to shipping products so I think all three expectant GPU hardware vendors have known about each others moves for far longer than any of us and their timing regarding hardware is entirely down to their own assessments on its economic viability and when they expect consumers to accept it.

It's really hard to say what Crytek actually have here and what is prebaked or realtime corrected trickery or similar until they release something that can be verified by a third party, they could have found some really innovative shortcuts to world reflections that will assist with all vendors and allow hardware RT implementations to focus on other areas like refractions and subsurface reflections rather than world reflections which will help a lot with things like water, rain, or human skin(Woo no more plastic people).

At first the Physx PPU was put onto the die of Nvidia cards. There used to be a workaround where you could run an AMD card as your main card, then let the Nvidia GPU act as a PPU. The only other option was putting it onto your CPU which tanked the performance.

But yeah, they've had plenty of techs like that. 3Dvision was another one that they just killed off (I wonder why?).

The difference of course being that in this case all three GPU vendors have already committed to supporting this API with the only exclusivity occurring through timing, NVidia can't create a wall garden around this feature because it isn't theirs, they've just slapped some branding on top of it.

I think a better comparison is with CUDA, it's not the only programmable/DX10+ GPU shader around but it was the first by a similar margin and so its branding has always stuck around.
