Product Information

On low-end hardware blending can also be quite expensive so for an image or rounded rectangle that covers most of the screen, the amount of blending needed for the interior of these primitives can result in significant performance loss as the entire primitive must be blended. Multisample Antialiasing There appears to be a LibUSB bug/incompatibility with modern motherboards like this. We have published a version of our "rtl-sdr-blog" drivers that should have a fix for this here. Replace the rtlsdr.dll file in the SDR# folder with the rtlsdr.dll file from the zip. Someone else has has also published a fixed DLL here which works for some people. Modern firmware updates to Ryzen should eliminate this problem. The non-threaded render loop is currently used by default on Windows with ANGLE or a non-default opengl32 implementation, macOS with OpenGL, and Linux with some drivers. For the latter this is mostly a precautionary measure, as not all combinations of OpenGL drivers and windowing systems have been tested. At the same time implementations like ANGLE or Mesa llvmpipe are not able to function properly with threaded rendering at all so not using threaded rendering is essential for these. If you are using the x64 version try the x86 version. This can also indicate a corrupted .NET install on your PC. Attempt a .NET repair or reinstall. QSGSimpleRectNode - a QSGGeometryNode subclass which defines a rectangular geometry with a solid color material.

First, if you already have some other drivers installed, please purge them from your system using the following commands: sudo apt purge With SDR# I get the error "The application has failed to start because its side-by-side configuration is incorrect". This can happen if you have set the sampling rate to the maximum stable rate at 2.56 MSPS. Adjusting the PPM value actually slightly modifies the sampling rate, so you may be pushing it over the stable limit. To solve this you will need to go down to a sampling rate of 2.4 MSPS. Press the Play button (the right facing triangle in the top left of the program). Your RTL-SDR software radio should now be set up and ready to use! If everything has worked you should be able to start tuning to frequencies. Setting QSG_VISUALIZE to overdraw visualizes overdraw in the renderer. Visualize all items in 3D to highlight overdraws. This mode can also be used to detect geometry outside the viewport to some extent. Opaque items are rendered with a green tint, while translucent items are rendered with a red tint. The bounding box for the viewport is rendered in blue. Opaque content is easier for the scenegraph to process and is usually faster to render.

This is most likely due to your USB port underpowering the RTL-SDR. This can easily happen with long USB cables, or unpowered hubs. Please try connecting the RTL-SDR directly to the PC to confirm. Custom renderer; the adaptation layer lets the plugin decide how the scene graph is traversed and rendered, making it possible to optimize the rendering algorithm for a specific hardware or to make use of extensions which improve performance. Another thing to try may be to disable Windows automatic driver installation. Instructions for disabling this can be found here. This error also sometimes occurs after the computer has been suspended - to fix it simply disconnect and reconnect the dongle. Batching only works for 16-bit indices. All built-in items use 16-bit indices, but a custom geometry is free to also use 32-bit indices. Windows updates sometimes overwrite the SDR drivers with broken Windows ones. Simply run zadig again and install the drivers again to fix it.Note: While OpenGL is used as an example in the following sections, the same concepts apply to other graphics APIs as well. This switch of animation handling mechanisms is transparent to the applications. What if vsync-based throttling is disfunctional, globally disabled, or the application disabled it itself? Note that the root rectangle in the code above is superfluous as the window is also white, so drawing the rectangle is a waste of resources in this case. Changing it to an Item can give a slight performance boost. The default renderer focuses on two primary strategies to optimize the rendering: Batching of draw calls, and retention of geometry on the GPU. Batching Setting QSG_VISUALIZE to changes visualizes changes in the renderer. Changes in the scenegraph are visualized with a flashing overlay of a random color. Changes on a primitive are visualized with a solid color, while changes in an ancestor, such as matrix or opacity changes, are visualized with a pattern. Visualizing Overdraw

The default renderer does not do any CPU-side viewport clipping nor occlusion detection. If something is not supposed to be visible, it should not be shown. Use Item::visible: false for items that should not be drawn. The primary reason for not adding such logic is that it adds additional cost which would also hurt applications that took care in behaving well. QSGGeometryNodes in the subtree of a batch root are pre-transformed relative to the root on the CPU. They are then uploaded and retained on the GPU. When the transform changes, the renderer only needs to update the matrix of the root, not each individual item, making list and grid scrolling very fast. For successive frames, as long as nodes are not being added or removed, rendering the list is effectively for free. When new content enters the subtree, the batch that gets it is rebuilt, but this is still relatively fast. There are usually several unchanging frames for every frame with added or removed nodes when panning through a grid or list. If you experience problems with SDR#, SDR++ is our second choice software that we also highly recommend.
