It helped with some mp4 files some locked up is it where I can adjust or tweak to get it running smooth on an old system mkv files they would lock up completely as well as most mp4 was just wondering what settings I need to adjust to get more speed?

Thanks this guide helped me out a bunch really appreciate it.Was having flicker problems using an older Radeon card quality is top knotch now.Have a sieki 4k TV is there anyway to play 2160p files  on an older system with potplayer its playing them now with the new settings but not anywhere close to fullframe rate just wondering if there maybe a software solution? or most likely going to have some faster hardware.Been waiting for the Nuvola player a standalone hardware solution for 4k.
