The tool for comparing the 2D performance with hundred of sprites has been updated including the new SDL 2.26.4 version (probably the latest version for SDL2 before SDL3 replaces it) with the Direct3D12 backend renderer. According to the person that took care of the implementation, he was thinking more on potential support for Xbox than…
Do you want to know how SDL 1.2, SDL 2 and SFML libraries perform in a 2D environment with hundred of sprites? Well, those libraries with several render backends (DirectDraw, Direct3D, OpenGL, software) are tested with this tool. For SDL 2, the new “batching” feature was also enabled and the results are very good. The…
Since 2002, this tool has been internally used for measuring memory bandwidth performance on different CPU architectures and, that “knowledge” was used on CRM32Pro (specific code paths) and also in other applications. Nowadays, this tools has been reworked and it is a complete memory bandwidth benchmark. The source code is available and also binaries for…
Back in the 2013 when I began to work on CRM64Pro, I did a quick survey of possible compression algorithms to use. With CRM32Pro, I used UCL (discontinued since 2004) and I wanted to use a newer and portable compression algorithm. I played a bit with zlib, LZ4, zstd and others but finally, I selected…
Varias personas me han preguntado por mail si existe diferencia en el rendimiento entre usar solo SDL o CRM32Pro y la respuesta es afirmativa. Ojo, que esto solo es cierto en modo software. En modo hardware son totalmente identicas. Hace ya mas de un año me dedique a optimizar el memcpy para que utilizara MMX,…
