Hey Hey.
I've been playing idle/incremental browser games on this platform for quite a while now, but only recently have I encountered this issue.

A lot of these games I've played were done whilst also watching random YouTube videos on my secondary monitor (I mention this to indicate that I've been able to do far more resource intensive tasks on my computer), but now I can't even run some of them without my browser grinding to a halt, even when I've shut down every other tab.
Is my computer simply degrading or is this something others have encountered as well?
