Anyone Else Laggy On Runescape?

I know I don't have the best computer in the world, but it's sufficient enough to run Runescape with no lag, but as of late i'm getting this crazy lag where it takes my entire CPU to run runescape. I got game boosters to even speed up my performance, but it's still not cutting it. I'm just wondering is anyone else getting this lag?

 

Nope, I get the same performance as I always did.

Try opening up your compute and using compressed air to clean it out. Sometimes dust accumulates and it causes everything to heat up and slow down.
