    Much like anyone in the graphics arena, Nvidia has been working a long time on actual real-time raytracing, the primary rendering technology used in the film industry. Today things get a step closer....

    Now Volta tensor cores make sense in gaming, RTX and his photorealism could be a true "game changer" and...

    ...another problem for AMD gaming GPUs.

    As always. nV is trying to push closed proprietary technology. I hope that industry will not support this effort in as big thing as is graphical API.

    But to the real time raytracing... few years ago there were domes with several GPUs and IQ was frame-time based. So, image delivered was image rendered in 16ms.
    Good or bad looking, but always 16ms. In other words users can decide between IQ and fps exactly as they want (in relationship to their HW compute power).

    Secondly, nV pushes it now, because they believe they have compute advantage. How shortsighted... as intel is behind corner with compute GPUs.

    So another Ambient occlusion, shadows and messed up reflections?

    Not impressed.

    Am I reading this right, DXR is accelerated by Nvidia's RTX technology, regardless to the title on Volta+ GPUs - but some games will feature "GameWorks Ray Tracing" libraries?

    Microsoft only stuff no thanks.
    I think is something they have to do since dx12 is not doing basically anything revolutionary and is not a game changer at all.

    Lol, by nature raytracing gives physically correct reflection, it's just your knowledge that's messed up ;)

    nV can't help their proprietary techs are good and better than the competition/open equivalents. It's not like they are Microsoft making really terrible proprietary technologies to expand their monopoly like Internet Explorer or MS Java VM, nV techs are actually well-designed and very high quality products.

    So Microsoft with DXR and NVIDIA making a RTX variant for Volta and newer, interesting.
    (From: https://www.resetera.com/threads/mi...ng-to-games-before-the-end-of-the-year.30559/ )

    A nice addition to graphical capabilities but with how demanding ray-tracing is I expect the initial showcases to be a bit lesser though probably still very impressive looking. :)
    (Over the next couple of years though this might see wider usage and slowly increase in complexity similar to effects for depth of field, ambient occlusion, anti-aliasing and so on.)

    EDIT: And there's the GameWorks page.
    https://developer.nvidia.com/gameworks-ray-tracing


    EDIT: And Remedy now and Northlight engine.

    This grainy look can be cheaply fixed. Once this low sample density raytracing completes its cycles, all that has to be written to mapped textures (information is there anyway) and then flatly rendered with high quality AF.

    Oh noes, a wiseguy lol

    So what, it still looks crap. Instead of using it for something more noticeable, noto for some glossy useless reflections, seen that with fake done far better then that sample shown in pics here..

    I stopped watching once i saw all that grain filter on steroids, I despised thge grain filter effect 20 years ago ps2 even in movies and still despise it

    I am intresting in ray tracing, how much hit it really put on gpu's and like always it need newer gpu's that arnt out, shocker seeing my 1070ti only 2 months old if that.

    Agree to disagree at least, but seeing the work Intel has done with ID tech engines and adding Raytracing to those engines, the results were noticeable at the time of release.

    https://en.wikipedia.org/wiki/Quake_Wars:_Ray_Traced
    https://en.wikipedia.org/wiki/Wolfenstein:_Ray_Traced
    http://www.q3rt.de/
    http://www.q4rt.de/

    It does break a lot of things in these engines(Notably ID Tech 3), but it does add some real time affects, using technology now it might be worth using finally in games.

    Also Quake 2 via path tracing. :)
    http://raytracey.blogspot.se/2016/06/real-time-path-traced-quake-2.html

    Not quite as "shiny" as what Intel turned Wolfenstein, Quake and Quake Wars into with their showcases though. :D

    EDIT: RIP Larrabee I guess and that one game that was developed to showcase it, forgot it's name though.
    (Partnered with Intel but it fell through or well it's been several years.)

    Don' t worry this is just an addon for DX12 wrapped in some marketing.

    Yawn...Yet Another "Real-Time" Ray Tracing app that *gasp* actually isn't...;) nVidia excels in marketing, I'll give them that, if not in anything else...;)

    It uses direct compute and HW async , stop taking nonsense.. AMD could use this today but with abysmall perfomance because IT IS ONLY IN THE RESEARCH PHASE

    Microsoft's DXR does, NVIDIA's RTX uses the tensor cores.
