I can understand the runtime detection, but why is pygame, presumably with its support for vectors, not compiled to use AVX if available. The math module doesn't produce the message, even though AVX can be used with integer manipulations, does that mean it has been compiled with AVX support or is it not checking for support? With, in this case, the pygame module having been installed from the Fedora repositories and producing this issue, does that mean I shouldn't install the modules from the Fedora repositories, I should use pip3 to install the modules as they may be compiled with AVX support? The message I got indicated that my cpu supports AVX2, how do I determine if it supports AVX512?On 20 Mar 2024, at 22:19, Stephen Morris <samorris@xxxxxxxxxxxxxxx> wrote: Just a couple of silly questions: AVX cpu's, both Intel and AMD, have been around since 2008, and this is 2024, why does Fedora not have support for the AVXx instruction sets?Not all recent CPUs have AVX, only some CPUs I believe. Therefore the preference for detect at runtime.
