@cobito Many thanks for the appreciation, with all the daily routine of returning to work in the last quarter I had not noticed to look at new bios and I had not skipped the notice about this new version of bios, so I continued with the Beta that was released which initially solved the problem 0x12B
Precisely now that you have commented on that % of performance, I scrolled up because the figure sounded familiar to me and in our thread, @krampak already mentioned that same margin of performance drop, so we confirmed firsthand that it is a fact https://foro.hardlimit.com/post/543813
I will update as soon as I can to see if there are improvements and it is fixed
