Hello ! I recently came across this blog post about external GPU performance being reduced by a misplaced optimization of dma buffers : [Fixing Multi-GPU performance, part 1 | Xaver’s blog](https://zamundaaa.github.io/wayland/2026/07/31/fixing-multi-gpu.html)

This doubles the performance in games, which is quite noticeable. The fix seems like it has been implemented in COSMIC and KDE 6.8, but I was wondering if it was relevant to make a feature request to implement it in Hyprland, or if that was already handled by a library.

Thanks everyone and have a great day !
