fps drops after a few games

[audioissues11]

Hi all. 

I am experiencing some drops in fps in overwatch after a few games. 

I just got a new computer that I'm excited about. I have a 240hertz monitor and when I play overwatch for the first few games my fps stays consistently around 230-240, even during team fights. 

After a few games, however, my fps begins to drop into the 150s during team fights. I have no idea why my fps lowers after a few games. I checked the temp on all my cpu cores and they never exceeded 60 Celsius. I have an i5 8600k. 

I did notice that the 1st and 5th cores do sometimes reach into 80% usage, whereas my other cores stay around 50-60%. I have my cpu clocked at 4.5Ghz. 

MY 1080ti temps also are not. My gpu usage stays constant around 60% and my temp never exceeds past 70 Celsius. My clock speed also is the same at 1911. 

I also have 16 GB of ram clocked at 3200 speed. I have no idea whats the issue. 

I have disabled hpet if anyone recommends that.

The core usage won't be pinned up high with all cores because Overwatch is not a very multi threaded game. It's really designed to be played on just about any scrap heap of a computer, since its esports status demands high accessibility. However, have you taken note of which maps the lower framerates occur on? It's possible that various maps have effects that challenge the computer slightly more.

I've personally not noticed this on my 8600k, but I run with a locked 90fps so it'd be much harder to see the big drop you're experiencing. Do your clocks drop after a few games?
