I've been playing some Gta V and Battlefront 2 recently, and its lagging even though it ran on my pc just fine for the past 2 years. It's always been 60+ fps but now I get below 60 and sometimes even 20-30.

My PC specs:
i5 7400
Rx 580 8gb
8gb ddr4
z270x gaming motherboard
1TB SSD

Only things I remember doing is updating my windows 10 and radeon driver to the latest version.
Something similar happened a while ago on Gta v, but I disabled most of the graphic settings in radeon software, and it sort of fixed the issue.
But now its happening again and changing the graphics settings in radeon software doesn't do anything(except lagging the game even further).
I haven't touched my PC in a long time(hardware-wise), so that shouldn't be the problem unless its something to do with my pc being too dusty inside.
What should I do to fix the issue?

Dust restricts airflow. Clean the inside of your PC.

Heat = Thermal Throttling

What are the temps of your system, idle and gaming?
