Could someone cross-check with the native Windows Video Player?
don't have MPV installed to test, but testing with a 8K60 HDR clip downloaded from Youtube shows the native media player allocating ~800 megabytes. (MPC-BE with madVR allocates ~2.1 gigabytes.) 1660 TI with a 6GB buffer.

8K is going to have huge memory requirements regardless of the codec, though; I'd expect it to basically scale by the number of frames prerendered by the player rather with additional codec overhead being negligible. I almost wonder if the suspiciously low numbers are due to decoding being too slow to fill some internal buffer, with the MS (libaom) decoder being slower than dav1d in MPC.
