Hi, i really need to know what is causing this performance problem.
It's been going on for over 2 years and we built this PC 4 years ago. I don't know how or when this started exactly since i didn't do gaming much around that time.
Here are some MSI Afterburner recordings of Apex Legends and Don't Starve Together. (Please read the descriptions.)
My power settings are on Performance Mode (100% on minimum and 100% on maximum cpu usage). And Bios settings are default and unchanged. I keep my chassis clean.
My RX480 has a problem where after every driver update, my pc doesn't detect it and it's known as Error Code 43. So i use 3. party programs to fix it. (atikmdag patcher and 6x gpu mod)
I brought my pc to a pc shop to understand the reason of the problem, but all i got was a format and thermal paste change. They said the GPU doesn't work well and is broken.
But one thing about that is, after the format & thermal paste change the pc performed much better. FPS wasn't going down from 75 but it was still not as good as it should be.
1 - 2 weeks later it was just like how it was before; way under 75 on low-mid graphic settings.
