Hi,

I have the following components:

CPU: Ryzen 5 2600
GPU: Nvidia GTX 1070 FE
RAM: 2x 4gb DDR4 @ 2400 Hz
MOBO: MSI B450 Gaming Plus
PSU: Be Quiet 400w

My cinebench 20 score was 2700-2800 (cant remember exact) - Max CPU temp was 72
My unigine Heaven Bench 4.0 scores were FPS: 245.1, Min FPS: 9.1, Max FPS: 440.7 when running the 1080p low settings test. Max temp was 80



My set-up seems more than capable at reaching high frame rates however when playing a game (Fortnite) all low settings @ 1080p it suffers weird drops every time I move the camera or perform some kind of movement etc. I cap fps at 160 and it dips to anything from 30 to 100 every couple of seconds. If I change the cap to 60 fps it drops to 30s etc.

I reinstalled windows, updated drivers, changed nvidia + windows to performance settings. No idea what it could be. When playing, the cpu and gpu usage is typically at 70% and 60% respectively.

nVidia webpage says the minimum PSU is 500 watts.

Pretty much every review site says 16gig is the minimum they recommend for a gaming machine...also the Ryzen 2600 runs best with memory in the 3200mhz range with the tightest timings possible which is typically cas14 for that speed.

Hey man I have the same CPU and GPU and a better PSU and RAM and let me tell you, it doesnt help with Fortnite. I have been trying to figure out the same problem you're dealing with for what seems like forever and have yet to find a solution. I just reinstalled Windows and that seemed to help, but currently on the road for work so wont be able to really tell until I am back.

Couple questions for you - did you ever have your PC debloated? Also have you ever monitored your Frametimes while playing Fortnite? Because for me, there's a spike every 61 seconds and that causes the FPS drops (as well as stutters or hitches). It can be brutal to play with.

Here's my build:

MB - Asus Prime X470-Pro
CPU - AMD Ryzen 2600 with Noctua U-12s cooler
GPU - GTX 1070 Ti
RAM -- G SKill TridentX 16 GB (2x8GB @ 3200 mhz)
PSU - EVGA 650 B3 650 W
Case - NZXT 500i Mid Tower
