Question PC severely underperforming, stuttering and weird GPU & CPU Usage ?

[Zamfik267]

Hello, so recently i’ve bought myself an RX 6650 XT 8gb Shappire Pulse, i had an RX 580..

But after installing the new gpu my pc was severely under performing.. i was getting wierd usages like 50% CPU 45% GPU in games but very low fps.. sometimes i would also get 100% GPU and 20% CPU or 100-80%CPU and 20% GPU.

in almost every game (low-med-high) graphics i get stuttering.. (on NFS Heat, Evil Dead, CSGO)

my rig
Ryzen 5 3400g
RX 6650 XT
Kingston Fury 16gb (2x8) 3200mHz RAM
600w PWS Bronze/Silver Certified
a320m s2h gigabyte motherboard
Crucial 256GB SSD
Gigabyte 255GB SSD
No Hard Drives.

this i’ve done to “reduce” my stuttering problems but kinda didnt work.

• Clean GPU DRIVERS install using DDU.
• installed Amd Chipsets.
• optimised some windows settings
• clean windows reinstall.
• windows downgrade & upgrade.
• checked if the GPU is installed correctly.
• checked if the RAM was installed correctly.
• benchmarked using FurMark and Userbenchmark.. (EVERYTHING WORKED FINE during benchmarks, no problems were found, worked fine)
