A rather unpleasant problem

I've noticed a problem. In Battlefield 6, after playing a few matches, the FPS drops by about 25-30%. This causes me to have to restart the game in order to get the FPS back to normal. It's very annoying. I believe it's related to a memory cache overflow (VRAM, RAM, or VRAM Cache) or something similar. I hope EA takes note of this and fixes it in the release version.
