[SOLVED] Is my CPU bottlenecking?

[Ztyler9_]

Is my CPU bottlenecking my PC? I play at 1080p and usually 144hz. I feel like sometimes my frames are too low for the card I have.

Maybe a little in certain applications, but not much the 8600k is a decent gaming CPU. at 1080p is where it might show some depending on the load but at higher resolutions not so much

i5 8400, not the greatest matchup with the 2080. Since you already have a 8th generation cpu you can update the bios and get a 9700K

my bad 8400

You will have to monitor core clocks in the situations that you feel like you don't have enough FPS,if your CPU is running full throttle in those cases ,4Ghz for single threaded and ~3.6-3.8 for multi, then yes your CPU is holding you back.

Just because an 8400 is not delivering the same FPS at 1080P as a 9900K, this does not mean the term 'bottleneck' should be be thrown about quite yet....; let's just say it's frame rates are understandably a tad lower at 1080P. The 8400 might not be a 9900K, but, it's then no i5-6400 either!

(There was an awesome comparison of CPUs with a variety of games using a 2080Ti on Youtube, look for '7700K revisited' by Gamer's Nexus....it shows 1080P and 1440P scaling from 9900K down to R5-1600 and below.)
