What does it mean when someone says a game is “CPU bound”?

Question

So I have a 1080p monitor, so when i look into games im interested in, i go and see how my specs perform at that resolution. When I was looking at Marvel’s Spider Man, the reviewer said that the game was CPU bound at 1080p. I assumed this to mean that the GPU won’t be utilized much, however when I eventually bought the game, I had a consistent 80+% GPU utilization. What exactly does being CPU bound mean then?

Answer 1

The GPU is able to work faster than the CPU because the way the developers decided to make their particular game and on what hardware you have in your pc. So the GPU has to wait on the CPU to be done everytime
