I am getting FPS drops in games like Just Cause 3, AC Origins, NFS Payback.
Even on lowest settings the problem is still the same, it is almoust unplayable.
But for example Far Cry 5 runs on 60 fps on high without any problem.

I have only 8gb ram. Can upgrading to 16gb fix the problem?
I have old HDD. Is it possible that it causes hard drive? Should I buy SSD?

Specs:
Ryzen 5 2600
MSI GeForce GTX 1060 6gb
RAM 2x4 gb DDR4

Please help me. Thank you for your reply.
