Pc has become significantly worse that is normal?

Hey people had 2 years ago for 900 euro to build a gamer pc

I have a graphics card geforce gtx 1060 gaming1 (current value 300 euro). Could play all games fluently league of legends played on highest graphics with 190 fps now I have only 90 fps and in some moments even 60. Fortnite I can't even play on the highest graphics must be set to medium, why is that?

ps: pc has never gone away because of that? This can never be that my pc has become so much worse in 2 years… Even some garbage pc can easily play league of legends on the highest graphics

Here are her very much my items that I built 2 years ago

Update driver. It's best to just format it

See what is limited, for example with MSI Afterburner, HWInfo64 etc

Hardware is not getting worse, only the software is more demanding.

Who knows what kind of "junk" you have installed in the whole time, which now possibly runs in the background? Tuning programs that make the system more broken than they use, etc… The hardware is not just so bad at consistent games.
After 2 years, you can also set up your system again, if you have done that and the PC still has the "poor performance", then you can ask again.

If I understand you correctly, you had a smooth gaming experience 2 years ago… Today with the same hardware, the same games are running worse… I know the phenomenon too well.

You can take a little bit in your own hands - usually a small performance boost is quickly noticeable on the software side. My recommendation:

Install and run CCleaner
Install and run ADWcleaner,
Install GeForce Experience (on Geforce Graka) or AMD Graka software and keep your drivers up-to-date (sometimes they are updated every day!)
Delete unused programs / games and defragment hard drive (HDD DEFRAGMENTATION ONLY, LET SSD HOW IT IS)

You have already exhausted about 1/4 of all the options in your power for which you do not have to spend any money. Unfortunately, games evolve so much that they become graphically more demanding / evolve over time. That's good in many ways, but rather bad for you at the moment. Here only helps to buy new hardware or optimize the graphics settings or screw down.

Let me thank you, if my tips helped you.
