The requirements are there for a reason, but as I can see, OP has an "adequate" PC. If he shouldn't be playing with his config, then the minimum requirements must be changed.
My PC does meet the minimum requirements. The game should playable on my end, and it is.

My PC does not meet the recommended spec. I shouldn't expect optimal performance... and I don't.

I don't think the problem is on SE's end or anything needs to be changed for that matter.
