blender 2.82, 2.91, 2.93, 3.0
Every aspect of blender is affected, cycles, eevee, viewport maneuvering, phisics simulations, evrything. Rendering and simulations increase the slowing down rate. Maybe a GPU memory flush button could be added as an alternative to restarting blender, or a timer that flushes memory if activated e.g. every five minutes. This could be manually inactivated for tasks that require the preservation of data in memory, but could be turned on while working in the viewport.
