An older AMD that was near the best you could get 5-6 years ago. I wonder if that's the issue.
Edit: it's an AMD FX(tm) 8320 Eight-Core Processor 3.50 GHz
It definitely can't be your GPU, so that CPU must be bottlenecking your performance. Have you tried reducing the graphics? Higher GPUs *can* do Maximum settings, but atm I think it's more stable to reduce to High or lower.
