Feature development happens to SDL3 in the main branch, which then can be back ported. |

Okay. No problem. @madebr |

Offhand, these look good. Do you have performance numbers that show the difference between LSX and non-LSX code paths for these operations? |
|
Hi @slouken ，we didn't find a good way to show the performance. We wrote these optimizations based on perf record results when using SDL to render videos. After these optimizations, and together with other optimizations merged before(see 50d8642), we find that the video renderings become more smoothly. |
