Question Very low fps on decent hardware

[alexsssk]

Hello guys!
So i recently bought a pc, a few months back, thinking that finally I could play competitively and smoothly, all of my favourite games(CS, Fortnite, Gta 5, TF2 etc).
My problem is that in every game i play, even though i have some decent specs, my framerates are awful, I am getting around 90-130-150 fps constantly, on CSGO, on the lowest possible settings and on a 4:3 resolution.I have tried all the launch commands, i have even tried reinstalling Windows, tho i am getting the same low framerate.
Same thing on Fortnite, i am getting 100-130 fps, lowest settings, 4:3 resolution and my framerate uncapped.
My monitor is plugged into my graphics card via DisplayPort.
My specs are:
AMD Ryzen 5 2600 @3.6 GHz
XFX RX 580 8 GB, latest drivers
Corsair Vengeance LPX Black 16GB DDR4 3000MHz CL 16
Gigabyte A320M-S2H Mobo
650 Watt PSU

I also have a Samsung LC24RG50FQUXEN monitor, @144hz, so my framerates need to stay above 144 to be enjoyable.

I have watched many videos on Youtube of people running MY EXACT specs and getting around 200-300 fps constantly in csgo and 170+ in Fortnite.
Any help?

MY EXACT specs

same motherboard, ram, and psu?

make and model of this 650w psu?
what the cpu/gpu temp and usage during the game?
ram running at 3000?
ram/hdd/ssd usage during the game?
malware scan the system?

 

[alexsssk]

Not the same mobo and psu, but something very similar.
*My mistake, it's a 600-Watt, a Segotep SG-600A
Imi game, ram is running at 2000 mHz at around 1300mb in afterburner
yep, i perform scans on a weekly basis

 

[rgd1101]

2000? you mean 2133?

 

[alexsssk]

No.While in game, ram runs at 2000(this is what msi afterburner shows).But my ram is running, by factory, at 3000MHz

 

[rgd1101]

[alexsssk]

It came With the system, same manufacturer as the case
