Can IPC Decrease Over Time?

[JBGRACEGOO]

I built my PC in June of last year with a GTX 960 4 gig and a FX 4350. Back when I started, It performed very well. Now though it appears to have slowed down significantly. the same games (GTA V, ROTR, The Witcher 3, etc.) perform worse with the same graphics settings. When I look at the Afterburner overlay it shows my CPU at or near 100% all the time, however when I go into task manager it shows only the game I am playing as any significant draw. This did not used to happen, so the question is: What would affect my CPU to make it perform worse in the same conditions?

Full parts list:

128 gig ADATA SSD

750 gig Caviar Blue HDD

Cooler Master Hyper T2

EVGA 600 Watt Bronze PSU

MSI 970A-G43 Plus Mobo

FX 4350

GTX 960 4 gig

Bogged down Windows install, virus? Tons of things that can go wrong.

nope IPC is instruction per clock, it won't go down over time. as tech improve IPC will also improve, making older chip seem slow.

True, but I doubt that's his issue. If his PC is noticeably slower than it used to be, its not just placebo.

The IPC of the hardware itself no, that shouldn't change from the day you got it but as mentioned through bloated software and such can cause other problems.

I would say this as well but everything else is still snappy, While on my desktop and in chrome utilization never goes above 20%, it is just in games where the slowdown happens.
