Setting to “tgsi”, for example, will print all the TGSI shaders.

Can also be installed via Pypi using pip install -U scons if setuptools is updated or wheel is installed. There is however an easy way to replace the OpenGL software renderer that comes with Microsoft Windows 7 or later with llvmpipe that is, on systems without any OpenGL drivers: The next major release will contain the cleanups. This is a work-around for softeare.

Fake MSAA Support Added To LLVMpipe, Yields OpenGL / – Phoronix

Development work on OpenSWR is now done on the mesa git master repository. This version is coming out as we are working on some major cleanups to the code. To use it put it in the same directory as your application. Update setuptools bundled with Python not required but is recommended: The fewer features the CPU has the more likely it is that you will run into underperforming, buggy, or incomplete code.


If the extension string is too long, the buffer overrun can cause the game to crash.

This version is the first to be released to the public. For a RPM-based distribution do: Other Sofyware drivers have their own environment variables.

Normally, no environment variables need to be set. Views Read View source View history. This will ensure that frame pointers are used both in C and JIT functions, and that no tail call optimizations lovmpipe done by gcc.

Copy it to a Qt executable’s directory since that is searched first when looking for DLLs and launch the app. For developers only Mesa Xlib driver environment variables The following are only applicable to the Mesa Xlib software driver. By default, gigabytes will be assumed. For Linux, on a recent Debian based distribution do: Build instructions are available for building on Linux or Windows. Standard Mesa environment variables provide the ability to run-time switch between OpenSWR and llvmpipe software renderers.

Hence we make our own build. Navigation menu Personal tools Sign in. The output is not really vsynced so native and naive OpenGL apps will run at random speed although it is throttled to some extent.


Should be set to a number optionally followed by ‘K’, ‘M’, or ‘G’ to specify a size in kilobytes, megabytes, or gigabytes. Overview OpenSWR provides a high performance, highly scalable OpenGL-compatible software rasterizer that allows use of unmodified visualization software.

For x86 or amd64 processors, bit mode is recommended. See the source code for details. The source code can be downloaded here: Y – override GL version to X. Environment Variables Normally, no environment variables need to be set. The charts below illustrate the compelling advantage of OpenSWR over Mesa llvmpipe in a real application scenario.

Especially useful to toggle hud at specific points of application and disable for unencumbered viewing the rest of the time.
