    Ice Lake (i7-1065G7) does. Pre-Everything (drivers, 3DM VRS feature test etc.)
    „3DMark VRS 66,89 (VRS off) - 94,09 fps (VRS on)“ in it's 25W-configuration, so around 40 % uplift.

    At Siggraph 2019, RTX was introduced to the following apps:

    • Adobe Substance Painter is relying on RTX ray tracing to accelerate baking performance up to 192× faster than CPUs according to Nvidia.
    • Autodesk Flame: RTX Tensor Cores improve visual effects and compositing workflows by accelerating Autodesk’s new machine learning technology in Flame v2020.1 helping artists isolate, extract, and change common objects in moving footage.
    • Blender Cycles: Nvidia OptiX 7 (RTX) with CUDA accelerates Blender’s open-source renderer.
    • Dimension 5 D5 Fusion: RTX ray tracing via UE4’s implementation of DXR allows architects and designers to simulate ground truth lighting and shadows.
    • Daz 3D Daz Studio: Nvidia Iray allows creators to assemble scenes with interactive RTX accelerated ray tracing to quickly build their artistic composition and render out in full fidelity.
    • Foundry MODO: RTX performance through OptiX in the completely redesigned MODO path-traced renderer offers a significant performance boost over CPU rendering.
    • Luxion KeyShot: RTX accelerated ray tracing and AI denoising for photorealistic visualization of 3D data for product design reviews, marketing, animations, illustrations and more via OptiX support in KeyShot 9.
    • Adobe Dimension CC and Chaos Group V-Ray provide users the ability to create fluidly, with great realism powered by RTX technology's RT Cores. Nvidia says Adobe Substance designer can deliver speed increases of up to 200 percent compared with earlier CPU-based technology by integrating RTX through DXR for light baking.
    • In addition, BlackMagic and Nvidia say DaVinci Resolve with DaVinci Neural Engine has implemented AI using the Nvidia AI libraries and is getting acceleration from Tensor Cores found on Nvidia RTX GPUs to accelerate inferencing.

    tested using https://www.testufo.com/ghosting#ba...tion=160&pps=960&graphics=bbufo.png&pursuit=1

    recorded via NVENC Geforce Xprience and NVENC+CPU OBS running on GTX 1660 SUPER driver 441.41 w10 1909

    • NVENC OBS


    • NVENC GFE


    • X264 CPU OBS
    Recordings made using NVENC results in stutters while recording made with X264 CPU was smooth.

    Googling around, people has been complaining about NVENC stutter since first half of 2019

    https://www.google.com/search?q=nvenc+stutter

    https://www.google.com/search?q=RTX+nvenc+stutter



    is NVENC on Turing (RTX and GTX 1660 SUPER) are defective in some cards? How's yours?

    Nice.

    With high quality VRS the visual drop is pretty much invisible, but performance gain is very scene dependent.
    Medium does get quite nice boost and with small amount of smoothing at places.
    Low quality is quite blurry on some detail, yet high contrast areas do keep their look quite nicely.

    Would love to see VRS demo with proper TAA, pretty sure that with materials which can handle minification properly this should look very nice.
    Oh.. and DoF/MB with VRS to reduce shading of very blurry areas.

    Workaround fix : limit the fps to 60 via RTSS Frame limiter

    Nvidia has some short videos on RT basics. The 3rd one talks a bit about RT core capabilities.

    Yup, really nice series.
    2nd video has nice comparison on rasterization and RT. (Doesn't do the usual RT simulates light crap.)

    One interesting thing on 3rd video is the limit of 1 layer for instancing, should be something I hope we will see improvement in future.
    I remember seeing video more in depth with this subject, but sadly couldn't find it again. (Basically RT needs compute when going from layer to layer.)

    DLSS 2.0 is officially announced


    DLSS 2.0 is already used in Wolfenstein Youngblood and Deliver Us The Moon. Results are very impressive. Mechwarrior 5 is based on Unreal Engine 4.0 and will get the DLSS2.0 treatment through the new SDK.

    It was a long wait, but looks like this feature will be implemented in lot of coming games

    Edit: oh I forgot to mention that DLSS2.0 doesn't need to be trained anymore by game, which will accelerate the adoption

    Control will be retrofitted with the new DLSS version.

    Very cool but where’s DLSS2X!

    Maybe for 2x you need Ampere to run the network with 4k input.

    Still a fair bit worse than DLSS off, but a LOT better than the original DLSS implementation. That's how it should have been at the start and then people wouldn't have complained about it as much as they did.

    DLSS was critized when it launched but now it seems really amazing. Is this tech also in the XSX, or is that a long shot since it's NV based? Much performance gains to be had.

    This specific implementation is NVIDIA specific, but Microsoft has demonstrated similar super-resolution tech on DirectML which would run on any compatible hardware, including XSX.
