The new driver with DXR support will be available in April. Extensions will be released as well which will allow RT to work on Vulkan.



Also interesting how NV is still using DXR benchmark comparisons between architectures on Rise of the Tomb Raider.






My expectations would be that I'll be seeing roughly RTX 2070 performance with RT on with my GTX 1080 or just below (most likely the latter) when comparing a reference 2070 to my custom GTX 1080 as it boosts higher. DXR on non Turing GPUs will not be fully utilizing the feature either. We'll see how it goes.

Once you experience a taste of RT, you'll have yet another reason to upgrade that GPU, KAC.

Let us know how your purchase goes.
 
My guess AMD cards will perform better due to better Compute Performance.

This has to do with Crytek showcasing RayTracing on a Vega56. Nvidia had no choice but to enable it for past gen cards.

It will come down too which is faster, Pascal or Vega. I'm leaning more towards Vega. We will never get any truth as to wether RT cores are actually viable or if Nvidia is purposely running Pascal slower in the driver.

I think this is a push by nv to tell devs that now it cakes sense to code RT effects in their games as the hardware user base is very large when you include GTX cards.
 
I wonder if this will just end up leading to dumbed down RTX running at really low rates so that normal cards can handle it.

That and I think the cat was outta the bag. AMD was going to be able to enable this feature on everything with enough DX12 capability for DXR and Crytek just released a demo showing off some RayTracing while making it abundantly clear that you don't "need" special dedicated hardware to pull this off.

p.s. Not to mention, with the right setup, I bet you could off-load DXR processing to a 2nd GPU.

I think it remains to be seen how much dedicated hardware adds to RT performance. I think it's premature to say you don't need hardware to do RT.

It's not premature to say you don't need dedicated hardware. Crytek has already shown it off. It may however require dedicated hardware to get some of the more impressive examples of ray tracing effects at playable frame rates though.

Right, they showed a limited software based partial reflection which is great but nowhere what say BFV has or the RT effects on Metro.
 
Is it me, or this starting to feel like game physics all over again?
 
The ray tracing on Pascal will be severely limited, much less rays and effect quality, and with lower performance.

So, the march towards ray tracing replacing traditional rendering has begun. It had to start somewhere.

We'll probably continue to have dedicated RT units from Nvidia for the next several generations until it's no longer needed.
 
Instead of cramming everything into one GPU, I wish we could use the full die for traditional rendering (no tensor cores) and then an add-in card that is exclusively tensor cores for RTX rendering. Give people the option of RTX, not force the technology down our throats for the minimal games that use it.

Imagine how much faster the 2080TI would be if it was a full die and not cut down for tensor cores. How much faster RTX could render on a die of ONLY tensor cores..

I was hoping AMD would go down this route but it appears they are going to follow suite.
 
Or I don't know.... let me dedicate a card to doing just the ray-tracing? Kinda like they did for PhysX.
 
At least us (sensible) peasants get to see what the fuss is about and whether it's worth it.

I've already seen it in action and all I'll say is.. if you're happy with it, fantastic.. but to me it's a total scam for the money. See you next gen.
