100% CPU usage while gaming

[Soyuz1966]

I have 100% CPU usage most of the time while playing games,I have an i5-9400F 8gb or RAM and a GTX 1650,I did look at my task manager and everything seems to be fine there (except the game) ,I read that it can be a faulty PSU but I don't know how to identify that issue and I did try using the high performance power mode and it doesn't work

thank you in advance

Hello and welcome.

 

So what's the problem?  Are you seeing poor performance while gaming?

Yep,Games such as battlefield 1 drop bellow 60 fps, in Titanfall 2 I get frame drops from 144 to 90 ,(I am using the NVIDIA experience recommended settings)

Do you monitor what your GPU usage is during gaming?  Is that also at or close to 100%?

depending on the game, battlefield it's at 60 max 80% ,in Titanfall 2 it's at 60 then it goes to 99% then drops again if you're wondering my CPU temp are at 57 °C

sounds like your 9400F is barely keeping up to the 1650, which shouldnt really happen for most games

 

im suspect you're lacking system RAM, is it constantly above 85-90% and starting to page file?
