RDNA2 - Any IRAY alternative?

Now that AMD has revealed their seeming amazing RDNA 2 Big Navi graphics cards, it makes me wonder about their use in 3D applications. NVIDIA dropped the ball big time with their recent GPU launches generating a great deal of frustration.

I was really hoping for the supposedly canceled RTX 3080 20GB version for use with DAZ and gaming. But that looks to be out the window. The $1500 for the RTX 3090 is steap. Moreover you can't find any 3000 series cards anyway. So what about AMD? Obviously with DAZ there is a problem. It uses IRAY which is propritary to NVIDIA.

I just started to learn Blender but in comparison to DAZ I'm far from proficient. The DAZ to Blender bridge doesn't seem to work too well either.

So the question is: Are their any options to seemlessly use AMD graphics cards with DAZ? Any external render engines I can export to without too much fiddling?

    AMD's stab at Iray has not gained any traction. Don't expect to see it in DS any time soon. To me it's vaporware. NVIDIA's scalper and bot problems may also show up for AMD. Nobody knows the full story and put little trust in YouTubers. Blender is still too complicated for most DS users/artists.

    If you go the Blender route, AMD is a very good option for rendering probably. I don't see AMD being supported by Daz Studio anytime soon.

    The Diffeomorphic plugin is getting better and better, Blender is getting easier. There is really no downside if you spent a bit of time learning the way.

    I just tried the Diffeomorphic plugin. It will require some learning to be sure. I take it I'll not be able to preview materials in DAZ with an AMD card either. So I may need to do those in Blender instead? (Assuming I get an AMD card that is...)

    Yeah, without a Nvidia card you are using your CPU to render. Which is still possible if you have a decent CPU and keep the render size small.

    That said, learning Blender can be very rewarding. Do the donut tutorial, it's very famous.

    I'm working on that donut :)

    It's not an alternative, no, because Daz doesn't support it.  And those benches you saw are probably with RT off not on, so there's that too.  We're also second generation NVIDIA RT asic, whereas AMD's solution to this isn't to go down the asic route.  They're repurposing compute shaders (I think).  I suspect their RT performance will be well below NVIDIA's, at least this generation, even if an alternative renderer was available.

    HOWEVER, I have hopes that Daz's Filament will continue to improve, perhaps adding DXR (or equivalent) capabilities, so we can get the best of both worlds.
