GeForce 411.63 driver : Ray tracing support... for Pascal* (*with 8GB VRAM or more)

Recommended Posts

Posted · Original PosterOP

In latest release of the GeForce Forceware drivers (411.63), NV made an entry for Vulkan 1.1 support :

Quote

New extensions for Turing GPUs:
− VK_NVX_raytracing (also available for Pascal GPUs with 8GB or more video memory, and Volta GPUs)
− VK_NV_compute_shader_derivatives
− VK_NV_corner_sampled_image
− VK_NV_fragment_shader_barycentric
− VK_NV_mesh_shader
− VK_NV_representative_fragment_test
− VK_NV_scissor_exclusive
− VK_NV_shader_image_footprint
− VK_NV_shading_rate_image

Source : LINK

Few of my thoughts :
1) Not sure how much it means to us (Pascal users), because it's only one extension... 
2) I get the feeling it's a compatibility only thing - to show how "bad" Pascal is, and how "good" Turing can be.
3) Maybe AMD also enables support for this at a later date (?).
4) It probably be too slow to be of any use on Pascal GPUs (or effect will be VERY limited, to keep framerate above slideshow level).

Maybe it's DX12 raytracing stuff only, without the RTX extras?

That's a really interesting find. I figured Nvidia would try and lock down proprietary ray tracing to RTX. If they are adding support, I'm totally gonna test it out in SotTR when ray traced shadows become a thing.

@Jurrunio That's the thing, it's Vulkan 1.1 specific.
No new DirectX 12 extensions can be found inside the pdf.
Only one footnote :

Quote

Microsoft's DXR developer package, consisting of DXR-enabled D3D runtimes, HLSL compiler, and headers

Maybe they are waitng for M$ to make a move, before they release RTX capable DirectX 12 driver (with all new extensions listed) ?

It's good to see that Nvidia saying RT is easy to implement is actually true, and that it's being made accessible like this. Also, glad to have a 1070 and have the very base requirements for it.


I WILL find your ITX build thread, and I WILL recommend the SIlverstone Sugo SG13B

 

Primary PC:

i7 8086k (won) - EVGA Z370 Classified K - G.Kill Trident Z RGB - Force MP500 - Jedi Order Titan Xp - The venerated Hyper 212 Evo (with RGB Riing flair) - EVGA G2 650W - Black and green theme, Razer branwashed me.

Draws 400 watts under max load, for reference.

 

Linux Proliant ML150 G6:

Dual Xeon X5560 - 24GB ECC DDR3 - GTX 750 TI - old Seagate 1.5TB HDD - Dark moded Ubuntu (and Win7, cuz why not)

 

EVGA G3 thread, BR/BT threadSeasonic Focus thread, S12II/M12II thread, Userbenchmark (Et al.) is trash explained, PSU misconceptions

So basically, the 1080 Ti and the Titan Xp?

They stated "8GB or more" in pdf.
So, everything above GTX 1060 6GB I guess ?
(ie. GTX 1070 / 1070 Ti / 1080 / 1080 Ti / "Titan XP" / Titan Xp / Titan V).

Oh, that title is very confusing. Should change that to "(*8GB or more VRAM required)"

That's not confoozing at all, tho a 1080 Ti should be able to RT I doubt a 1070 will do much
