Ryzen 5 1400 only one core pegged while gaming

Every time I try to game, only one core on my CPU gets pegged while the others do not really do anything. The same thing happens in windows. I'll attach a picture while playing fortnite (I should be getting approx. 100FPS, I get 30-50.) It's odd, because I was playing the game yesterday with the exact same settings and it was fine.

My specs are:

  • Windows 10 Pro 64 bit
  • Biostar X370GT5 
  • Ryzen 5 1400  (overclocked to 3.8GHz, it has been stable with this system for a couple of months)
  • 1x8GB DDR4 Crucial 2400 (Overclocked to 2666, has been stable for months)
  • MSI Gaming GTX 970 4GB (overclocked +125 on core, +300 memory, was stable)
  • Intel 530s series 80Gb Sata III SSD, Seagate 2TB, Hitachi 1TB
  • EVGA 500BQ (80+Bronze)

Well, most games only take advantage of single core performance so that's pretty normal for your first core to take on most of the load.

 

Try running a CPU stress test and see if every core is maxing to 100% if you want to be sure.

Aida64 would be a good one to do that with.

Monitor your temps while you're at it and make sure nothing is going over 80 degrees.

Also check the bottom graph in AIDA64 for any thermal throttling while it's going.

 

I think you're fine though.
