So I've recently purchased components to build my first ever pc, but after booting it up on the 8th of December 2021 I've only had about 2-3 weeks of good FPS in games, I was playing and getting just over the 200 FPS mark and now on the same games in getting around quarter of what I used to.
My PC specs are -
Windows 10 Home 64Bit (the unpaid version)
Ryzen 9 5900X 12-Core Processor
16GB RAM Dual Channel HyperX Fury DDR4 1330MHz
ASUS ROG CrossHair VIII Dark Hero AM4 MotherBoard
4095MB Nvidia GeForce RTX 3080 Ti (SUPRIM)
and 2tb of SSD storage
I've had 2 friends suggest possible fixes but I'm not sure if its correct, my ram may need changing and the other friend said i should buy the paid version of windows 10 because Microsoft eventually caps FPS to make you buy the full version but im not sure how much of this is true.
I'm completely new at any of this pc stuff so any help would be appreciated.
Also if its any help here are a list of the games I play
Arma 3 (modded)
Dayz (modded)
The Hunter Call Of The Wild
Deadside
(All of which used to perform well)
Thanks.
