r/PC_Builders: A PC Building help/discussion subreddit.

My PC specs: I5-9400f - Gtx 1660 super - 8gb Ram

I build this pc a while now and I never noticed performance issues cuz I never looked up if I was having best possible performance. For some context I used to play Minecraft, Rainbow Six Siege and CD:GO Constantly hitting +200 fps on competitive settings(Both fps titels). But recently R6 had some updates and I noticed A LOT of shit, starting with frame drops going all what down to stutering, screen freeze and input lag. I downloaded that software from MSI also known as MSI afterburner by the intelectuals, and noticed that my GPU was basically caped at 65%. I don't know if it is a settings I missed that i accidently activated but it should (based on public benchmarks and indications) not bee facing these problems at all 😞.
I had enought when I downloaded my fav game for its pc version ( The Last Of US part I) and that crab when 25 ducking fps and my CPU was on 70% Usage, and when I scalled shit up to higher settings I get a SHT TONE on input lag and freezing and the diferente ist significant. Can some one help me out on this? Is it the GPU (something burned throught) or the CPU? Or the RAM? Or some settings on the BIOS? IM LOST !AAAAAAAAAA
