CPU temp rises, frames drop, (not a heavy load)

[DVA]

Hey everyone, so I'll make this short and sweet. When I am playing one of my usual MMO's I have had a sudden frames drop. The game is an older one so it caps at around 60 frames or so, but I've noticed at around 5 hours of continuous game time (I work a lot so I deserve this relaxing time :D) and watching movies that my CPU temp will suddenly spike up and my memory usage becomes high and then my frames drop from a constant 60 to a near 30!

 

So in short: After 5 hours of game time, temps spike, frames drop, high memory usage. I have two clients of the game running at the same time, and Netflix or Chrome open. 

 

I am needing some serious help, my PC should be running flawlessly. The problem is solved by a simple restart. My temps drop back down to the low 30's and everything is heavenly again. 

My CPU temp spikes from around 32C to 50C, which is still nothing to worry about, but it's still a spike that happens along with the frame drop and high memory usage. 

Ambient room temps on average - 69-72F (20-22C)

 

PC Specs:

 

i7 8700k OC'd to 5Ghz @ 1.32V

1080ti SC2

16gb's Corsair 3000Mhz

Corsair h115i Pro

EVGA Z370 board

EVGA G2 550W

 

 

Thanks everyone.

Turn off vsync.

 

Vsync operates in steps.  Depending on the monitor.  Typically 0 - 15 - 30 - 45 - and 60. so if your PC cant output 60 or more FPS.  then vsync drops to a lower step.  so if for an instant your PC can only render 55FPS.  Then you drop for a second to a 45FPS cap and then back to 60 again a second later. 

 

If your display only support 30hz or 60hz then the 45hz step is eliminates.  so if you PC can only do 55FPS, then its going to cut everything and run at 30, until your PC can do 60+ FPS again.

I'll have to try this later and come back with an answer to you, but I'm still curious as to why my PC would suddenly not be able to run the MMO? 

I have noticed it going on for 2 weeks all of a sudden. I don't have anything malicious, I've checked. 

 

I'm stumped as to why a rig as strong as mine would drop in performance when under load on an old game at around the 5 hour mark EVERY time?

Could be a number of factors.  When i used to play WoW there was one zone i would go to and get shit like 20 FPS.  then another zone over be over 75FPS.  it all depends on how optimized the game is, there could be a memory leak somewhere, or the 2 clients start having issues with addressable VRAM.  Hard to say exactly.

Memory leak or the game is getting close to 4GB of memory? This can be problematic for older titles.

Anti virus scan? Windows defender? Look at the task manager when this happens and see what's taking up the CPU usage.

I agree with corrado33. A few years ago I had a similar problem where a virus would crash my computer by taking up all of my CPU and RAM usage. I only found out later by looking at task manager. Although unlikely, it could be helpful to see if a specific program is eating up your ram and cpu.
