3D-Tech News Around The Web / RenderDoc 1.10 released
« Last post by Stefan on Today at 06:31:25 PM »
Version v1.10
 This release is primarily focussed on some optimisation and speed improvements, mostly during capture time while idle in the background but also applying to capturing in some cases and some improvements to replay speed. The amount of speedup you'll see will depend on your application's usage and API, but the worst cases before should be significantly improved. There are still some cases that remain to be improved in future.
Binary releases are available on with zip and installer for Windows and binary tarball for linux.
Main Highlights
  • Reduced idle overhead while injected into programs, while not actively capturing a frame.
    • All APIs have seen improvements, though some will see greater savings than others especially depending on API usage patterns. Modern APIs (D3D12/Vulkan) with high frequency API calls and command buffer recording will likely see bigger savings.
  • Improved speed of capturing a frame on Vulkan when GPU-local host-visible uncached memory is mapped.
  • Improved application startup time from cold.
  • Improved replay time for switching events for Vulkan captures with large numbers of descriptors bound with few actually used (i.e. 'bindless' type workflows).
3D-Tech News Around The Web / NVIDIA Quadro driver 456.38
« Last post by Stefan on Today at 04:56:31 PM »
 Release 455 is a Quadro New Feature (QNF) driver. QNF drivers provide users the flexibility to try new features made available outside the launch cycle of longer-lived Optimal Driver for Enterprise (ODE) branches. QNF drivers are tested for workstation environments and are recommended only for those users who need specific features mentioned in the release highlights or release notes.
 Quadro Release 455 comprises the entire suite of Quadro features, as well as all NVIDIA Studio Driver features.
 For the most stable and fully supported enterprise driver please use the ODE graphics drivers downloadable from the main NVIDIA driver download page.
 New in Release R455 U1
 New Studio Features
  • NVIDIA Deep Learning Super Sampling (DLSS) support added for D5 Render and SheenCity Mars.
  • DLSS is an AI super resolution algorithm that utilizes RTX Tensor Cores to boost frame rates, increasing viewport interactivity while maintaining visual fidelity.
  • Support for NVIDIA Broadcast application, which uses the dedicated Tensor cores in Quadro RTX GPUs to offer:
    • Noise Removal: removes background noise from microphone feed.
    • Virtual Background: removes the background from webcam feed and replace it with an alternative image, Windows app, a game, or subtle blur.
    • Auto Frame: zooms in on the user and applies AI to track head movements, maintaining centered frame.
 CUDA 11.1 Support
  • Added new PTX Compiler static library that allows compilation of PTX programs using supplied APIs.
  • Added the 7.1 version of the Parallel thread Execution instruction set architecture (ISA).
  • Unified programming model for:
    • async-copy
    • async-pipeline
    • async-barrier (cuda::barrier)
  • Added hardware accelerated sparse texture support.
  • Added support for read-only mapping for cudaHostRegister.
  • Multi-threaded launch to different CUDA streams is supported.
  • CUDA Graphs enhancements:
    • improved graphExec update
    • external dependencies
    • extended memcopy APIs
    • presubmit
  • Introduced new system level interface using /dev based capabilities for cgroups style isolation with Multi-instance GPU (MIG).
  • Improved MPS error handling when using multi-GPUs.
  • Users can now configure and query the per-context time slice duration for a GPU via nvidia-smi.
  • Improved detection and reporting of unsupported configurations.
 Fixed Issues in Release R455 U1
  • [PTC Creo]: Improved the application wireframe performance.
 Open Issues in Release R455 U1
  • [Alchemist]: The application crashes when either changing the display resolution or switching to another display with a different resolution.
  • To workaround, avoid changing the resolution, or disconnecting from or connecting to an external display with the application opened.
3D-Tech News Around The Web / NVIDIA Nsight Graphics 2020.5

Just a heads-up:
Compared to driver 456.38 this driver adds support for


More important - it breaks OpenCL (in any app)
I guess NVIDIA started OpenCL 3.0 development and put some broken code in this driver branch?

  • Added support for the following GPUs:
    • GeForce RTX 3080
      GeForce RTX 3090
      GeForce MX450
  • Fixed a bug that prevented 8K displays from being used in portrait orientation on Pascal and earlier GPUs.
  • Fixed a bug which caused excessive CPU usage in Vulkan applications which create a large number of VkFence objects. This was particularly prevalent in the Steam Play title Red Dead Redemption 2.
  • Added support for a new device-local VkMemoryType which is host-coherent and host-visible. This may result in improved performance in some applications. Applications which are known to benefit from this new VkMemoryType include: DXVK Title DiRT Rally 2.0, Steam Play Title DOOM: Eternal, and DXVK title World of Warcraft.
  • Fixed a bug that caused WebKit-based applications to crash when running on Wayland.
  • Fixed a bug that led to display corruption at some resolutions when using an NVIDIA-driven display as a PRIME Display Offload sink.
  • Fixed a bug in a SPIR-V optimization that may cause conditional blocks to not execute.
  • Fixed a bug where calls to vkGetRandROutputDisplayEXT with unexpected inputs would generate X11 protocol errors. (
  • Fixed a small memory leak during exit of the NVIDIA EGL driver.
  • Implemented support for the NVIDIA NGX Updater. See the "NGX" chapter in the README for information on how to configure this feature.
  • Removed support for the SLI modes "SFR", "AFR", and "AA".  SLI Mosaic, Base Mosaic, GL_NV_gpu_multicast, and GLX_NV_multigpu_context are still supported.
  • Updated Base Mosaic support on GeForce to allow a maximum of five simultaneous displays, rather than three.
  • Fixed several synchronization bugs that could momentarily lock up the X server when moving/resizing/focusing OpenGL and Vulkan windows when PRIME Sync was enabled.
  • Added NVIDIA VDPAU driver support for decoding VP9 10- and 12-bit bitstreams. Note that VDPAU's presentation pipeline and OpenGL-VDPAU interop does not support 10- and 12-bit video surfaces yet. See the "VDPAU Support" appendix in the README for supported decoder profiles.
  • Fixed a bug that could cause dual-link DVI to be driven over a connector that only supports single-link DVI, when "NoMaxPClkCheck" is specified in the "ModeValidation" X configuration option.  Note this fix may cause behavioral changes for configurations using this option.
  • Fixed a regression that allowed displays to enter DPMS mode even when DPMS is disabled in the X server settings.
  • Updated nvidia-settings to allow continued interaction with other pages and help content while editing application profiles.

This thread might not have TRUE HW ray-tracing for reflection error found

It's because ray tracing is not used. This is likely a simple rendering.
