HIGH GPU/CPU Usage 99%

Recommended Posts

Posted · Original PosterOP

I have an MSI RTX 2080 Gaming X Trio. Every time I launch Rainbow Six Siege, I am at 99% GPU usage at the main menu, and in game I am 90%-99%. When I play an older game like CS:GO I am in the 80% GPU usage and my i7 8700 CPU usage is in the 85%-90% range, which should not be happening on this type of build on a 9 year old game? This has been happening for a few weeks. I use MSI After Burner for custom fan curve, and Riva Tuner for overlay to display these numbers. Here are the steps I have taken: Rearranged settings in Nvidia Control Panel. Reseated RAM. Reseated GPU. Blew all dust out from PC. Applied new thermal paste to processor not GPU. Reinstalled windows. Updated/Flashed BIOS to latest version. Spent an hour and a half on the phone with intel who confirms chip is known good, saw test results. Spent an hour with Corsair tech support who said RAM is known good. Attempted to call MSI tech support. ZERO help the guy was just trying to get off the phone. I am at a loss at this point, Hardware seems to be known good however no one can give me an answer? Here are the specs I am running. Keep in mind this build is less than a year old.

Nice. 99% on the GPU and 90% on the CPU is solid af, that means the game is actually using your game to the fullest. 

High usage numbers are only a worry if your performance is low. If it's performing up to snuff then again, that just means the software is taking full advantage of your hardware. 

Always try googling your motherboard and looking at the spec sheet and manual - OEMs keep those up for a reason - and maybe you'll learn something 🤔

gpu usage statistics aren't very accurate to the amount of work the gpu is doing unlike a cpu usage graph.

It more or less just shows how much of the gpu is being used and not really how hard the gpu is actually working

Those 500 FPS in CS:GO you are likely getting is why its working so hard ;) Because it can, so it will.

Need some context. FPS would help. 


Plenty of games have menus that have high usage. Which is why some games are actually smart and have two different FPS caps. 


Enough frames can cause this to happen. Assuming you are at 0-5% at idle for both at the desktop.

Thank you all for your replies. My main concern is that the temps of the card will rise in a short period of time and I would like to play longer than 30 min before I am hitting 70c on my GPU temp. I have my FPS locked on rainbow six at 120fps even though I am using a 1440p 144hz monitor. I feel like iCue could be a major factor so I uninstalled it and it helped a little, however I dont know how to manage fans and mouse settings without it. CS:GO is running like almost 300fps at any given time, I am not sure how to lock the frames on that game?

Really don’t see why you want the card to take longer to heat up. It’s doing it’s job, it’s gonna happen quick. Turn the fans to max before you start. Should get you a few extra seconds. Being that how won’t change anything aside from the boost state. Which you don’t care about if the card is on air. 


Cs may use a console for frame control. Googling it may yield what you need.
