Getting Bad Stuttering in New PC Build

Hello. So ever since I built my pc a few days ago, I have noticed stuttering in most of the games I tried (1% and 0.1% low framerates are very low but average framerates are very high). What could be causing this and how do I get rid of it? I have well above 60 fps in all games and v-sync off. I play at 1080p 144hz. GPU and CPU temps are great. Something I did notice is that CPU usage seems higher than it should be. However, nothing is eating up the CPU in task manager other than the game.

Specs:
-i5-8400
-Asus 1070 Strix OC
-16GB DDR4-2666 (dual channel)
-Crucial MX500 1 TB SSD
-650W 80+ Bronze PS
-MSI Z370-A Pro MB

Just curious mate! Which monitor are you using?

Samsung CFG73. 1080p, 144hz, VA.

Try playing at optimal settings on GeForce Experience.

I figured out the problem. As good as that i5-8400 is, it’s not quite powerful enough for a 144hz monitor. I was already kind of suspecting this when I saw that my cpu usage was higher than it should be. My suspicions were confirmed when I overclocked the cpu a little and the stuttering decreased. I bought an i5-8600k which should be a perfect match for a gtx 1070 and a 144hz monitor.

Oh that’s great thanks for sharing it here.

Ok so I bought the i5-8600k, more RAM and a corsair h100i v2 cooler and although the stuttering did decrease, it is still definitely present. In rocket league for example, I have an average fps of like 240, however it constantly drops to around 60 fps. It makes the game feel sluggish, despite the high framerates. and yes I tried capping it at 144Hz and 60Hz. It has to be a hardware problem right? I literally did a clean install of windows 10 and installed nothing but the games I was trying.

Hmm, im not sure about this :frowning:
