i dont know if that has a specific term, but it generally revolves around the render queue. different players/renderers handle what happens when the render queue isnt ready to play.
MadVR (a popular upscaling renderer for MPCHC) for example has an option to pause render queue till full.
one player may have it setup as always play each frame which causes random slowdowns/speedups, other might implement it as drop frames to always be time synced correctly. the latter is especially used if the hardware is too slow to display the content in realtime.
yeah this is the circle of ownership because the only way to get your account back at this point is social engineering, which is a serious topic about getting accounts hacked which different companies will handle seriously, as it requires a level of “trust me bro” on identity, If possible, id try to look for a CS that will take receipts of the game purchases to help further prove your identity.
