Thanks for reading my topic. I have posted about that issue in github’s Retroarch repository https://github.com/libretro/RetroArch/issues/19183, but not see if any Retroarch dev has accessed that topic. The problem is Retroarch in recent builds are reporting wrong value for “Estimated Refresh Rate”. System is CPU AMD FX 6300 and GT 640 using driver 470 and Linux Lubuntu 24.04 using kernel 6.14. Please see the image below.
However only happen issue in dosbox pure doing sound fx bugs and slowdown https://github.com/schellingb/dosbox-pure/issues/754 . Others cores not does any issue. I only want report that issue Retroarch devs read it. Have a nice week.
