CPU at 100% when streaming even after upgrading to Ryzen 5 2600

masonman1118 · Jan 19, 2019

So I had been experiences really bad frame rates and 100% CPU usage during streaming especially when it was Fortnite. So I decided to upgrade from my AMD FX 8300 to a Ryzen 5 2600 thinking it would fix this issue. It hasn't, and I have no idea why.

Here are my specs:

CPU: Ryzen 5 2600
GPU: Radeon R9 380
RAM: 16 GB DDR4 2666MhZ
Motherboard: ASUS Prime B350-PLUS AM4
PSU: Rosewill 650W
HDD: WD Black 1TB
OS; Windows 10 Pro

Stream settings:

Resolution: 720p at 60fps
Bitrate: 3500kbps
Encoder: AMD (Have tried Hardware x264 and it's worse)

Fortnite Settings:

Resolution: 1920x1080
Frame rate Limit: 120fps
View Distance: Epic
Everything else: lowest settings
VSync: Off

Not sure what the issue could be. Would really appreciate any help, thanks!

you need to reinstall win 10 before after upgrading your CPU and MB. just plugging in your old HDD/SSD is not advisable

If you don't limit your FPS fortnite will use a lot of resources,way beyond what it should use compared to less FPS.
Also the game is very touchy about anything else (that uses a lot of CPU) running in the background.
Use the inbuild FPS limit to find the max FPS where you can stream smoothly.

TerryLaze :

I should have mentioned I have my Fortnite capped at 120fps. I have tried 60fps also and the same problem still continues. I’ll add my fortnite settings to the post.

As mentioned by norcalsc you do need to do a complete reinstall of Windows when you upgrade motherboards. If you already have then I would suggest being sure to update you BIOS and any chipset drivers

Whats your "GPU Priority" and "Priority" Values under HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Multimedia\SystemProfile\Tasks\Games in your registry ?

christophergeo :

GPU Priority = 8
Priority= 2

Bump. Would really appreciate any more ideas. I have tried all the aforementioned fixes but to no avail.

I might add that I have tried turning Fortnite down to the absolute lowest settings and resolution and still have the exact same horrible framerates. (30-40 FPS)

I know this shouldn't happen on this powerful of a CPU, there must be something wrong I am missing.
Thanks!
