    I would imagine it would be similar to how you play now. Don't you have to choose a resolution that is available within the game video settings even though your preferred resolution might not be there?

    generally no both those resolutions are selectable in game the exceptions are old games that cant handle widescreen aspect ratio's and expect 4:3 or 5:4

    The point is that most PC games are designed to be resolution agnostic. It's a fair criticism of DLSS that you're restricted to whatever resolutions they decide are available due to having to perform training at each resolution.

    Agreed, the point is what DLSS resolutions to include is a studio/developer decision regarding their game.
    Nvidia's initial improvements on DLSS up-scaling focus on quality/performance over ground truth, but it's hard not to imagine DLSS up-scaling research is already underway on resolutions beyond what we have seen, especially since 8K monitors/TV's will become more mainstream similar to 4K hardware did.

    Yeah, those mean developers. Nothing to do with a technology so dependent on specific resolutions. But we can't say anything bad about Nvidia!

    So much shiny-shiny, but the core lighting isn't any better. I wish RT was contributing more to the light realism rather than reflections.

    Following the suggestion of @troyan, I tried out this free small game called Beyond Evolution, it's a UE4 title with support for RT shadows, reflections, and indirect shadows (same way as Control), made by one developer, it's a simple platformer game really, with nothing fancy in terms of gameplay or story.

    The game is playable maxed out @1440p30 on a 2080Ti, RT indirect shadows from the skylight practically cuts performance from 90fps to 30fps, though the developer states that it's highly experimental. Other RT effects like shadows or reflections only cost 10fps or so (combined). All RT effects look significantly better than their non RT counterparts.

    The game was created quickly in a very short amount of time according to the developer.

    Zenobia is a next gen indie title, using UE4, it will be using RT reflections, ao and shadows

    Is it actually using RTX or just DXR?

    All DX12 RTX games use DXR (and can run even on Pascal GPUs), Vulkan games use an NVIDIA specific extension for Ray Tracing, and thus are only exclusive on Turing GPUs.

    So shouldn't we classify them as DX12 DXR games instead of RTX? And only list the Vulkan games as RTX games?

    Yes I think so, thing is all DX related games were treated and marketed as RTX games considering RTX GPUs were the only game in town.
    We also had so many threads about RT, RTX, console RT, compute RT .. etc since the dawn of RTX (a year and a half ago), so it became a mess of threads.

    Unreal Engine uses VULKAN? Even on WinOS PC?

    Unreal Engine can use Vulkan on any supported OS, it's up to game devs to pick which API(s) they prefer

    What indicates it's "RTX" only?

    RTX is a marketing name for a stack of new Turing technologies (which include DLSS among others). Nothing is "using RTX" since you can't program for a brand name. Something using these new Turing features is accessing them through either D3D12, Vulkan (with vendor extensions), DirectML, NGX or CUDA.

    In the context of the conversation, it was regarding RT features that were locked to Turing cards only. And in the course of that conversation, pharma inferred that it's RTX or Turing only. So I wanted to know why it was implied when there was nothing in the tweet or the video to indicate as such.

    Unless it was the #RTXon in the tweet, in which case *gag*

    Very good!

    Edit: I believe Khronos is currently trying to bring a cross vendor extension based on Nvidia's the VK_NVX_raytracing extension. They planned to speak at GDC 2020 with the different vendors though likely will be held offline.
