is there any way to put my extra memory to use to play av1 files if my cpu overloads? Debian 12.11

debian 12.11

system memory size: 31GiB, 2 15.5 GiB cards

cpu: Intel(R) Core(TM) i7-7500U CPU @ 2.70GHz, version: 6.142.9, size: 3268MHz, capacity: 3500MHz, width: 64 bits

no graphics card whatsoever

computer can play h.265 and equivalent without troubles, provided video file is no higher than 1080 p.

Computer can play av1 files no higher than 1080 p only if I shut every other application down. If for example I run a browser and an av1 file with either mpv or vlc, system shuts down.

Can I put all that memory to use and avoid overloading the cpu?
