Puzzling frame rate instability

Hey everyone,

I just want to pick the forums brains about an issue I've been having lately, I'm not sure exactly what to do about it. So, a while ago I noticed my FPS in games such as Overwatch and other games I play was sort of unstable/ on the low side. I use a 144hz monitor so it's important that I maintain above 144fps in Overwatch especially. Specs: i5 4690k, EVGA GTX 970sc, 16gb 1886mhz DDR3. In theory I should be able to run Overwatch at a constant 154 fps, if I have the game set to display based, yet it keeps dipping below 144, to 120-130 something.

I've restored my PC three times in the last month and a bit trying to fix this issue but it's still present. Initially after the system restore Overwatch will run perfectly fine, how I would expect it to run. It always seems to slow down again though, and I honestly have no idea why. It could be my CPU is getting old as I believe it's something like 3-4 years old. My GPU should not be a problem as it's about 2 years old, although I recently carefully replaced the thermal paste on it not too long ago. I didn't see any immediate issues from that replacement. I'm considering buying some thermal paste remover compound and to redo the paste. Other than that I'm completely stumped, my CPU and GPU temperatures are fine and should not be causing issues.

You're expecting WAY too much, and quite frankly, theories are generally formulated by those with lots of expertise and research data. You didn't even so much as say what game settings you're using. Thus it's not a theory, it's speculation.

All it took for me to research this was a "overwatch 4690k, gtx970" Google search. The very first link showed the game averaging no more than 100 FPS on Ultra settings.

A GTX970 by today's standards is no more than a decent midrange card, especially since it's somewhat crippled by an actual VRAM capacity of 3.5GB, not the 4GB they claimed.

A lot of people get sucked into 144Hz monitors and assume it won't be all that hard to maintain 144 FPS. The reality is most with such displays end up...
