FPS/Computer problem (pls help)

I got an I7 3770k overclocked to 4.6ghz that has a stable temperature around 80°C
The system also has gtx 970 sli, which are slightly overclocked which have stable temperatures of around 50°C.

The problem I am having is that I can barely manage to keep above 144fps consistently. It fluctates around the high 180’s to below 100 depending on the situation but never even close to 300fps.

The cpu usage consistently stays around 50-70% and my gpu’s never go above 50% usage.

Is this just Overwatch sucking at optimisation or is there something wrong with my pc?

I would like to note that Overwatch and my system run off an SSD which is virtually full with only 1gb free if that affects anything.

Try making sure your graphic card is running at maximum performance not running off the motherboard chipset either, this has been a growing problem that I have been seeing among NVidia users.
