Was playing League of Legends, my game kept crashing every time I'd Alt+Tab to type a message in Discord.
After the game ended I looked at Task Manager, and its showing my GPU usage spiking every other second to 100%, looking at what Program is using my GPU, it was at first League of Legends Client, and now its "Desktop Window Manager".
This happened a week ago, thought it was drivers, updated my drivers, seemed to solve it, same problem happening again.
#GPU Rapidly spiking to 100% usage every other second

Anyone have any idea what is going on here?
rocky ivy
Your GPU is supposed to be at 100% utilisation, as for your crashing problem you will most likely find your answer by googling the game and how to replicate the problem
regal hedge
This is 100% incorrect lol
a gpu should not be at 100% utilization just in the league of legends client (non 3D rendered), and should not be spiking from 0-5% -> 100% every other second.
Also, here, after restarting PC (as the issue is intermittent) here is a normal capture of GPU usage. 0.9%
rocky ivy
a gpu should not be at 100% utilization just in the league of legends client (no...
your 0-5% -> 100% Can be caused by many issues, And LoL does the same thing when I alt tab, and it's most likely spiking that hard Because you're switching between 2 applications,
regal hedge
Yeah, like I said the problem is intermittent. Its no longer happening now. Just wish I knew what the cause was so I can prevent it from ruining games in the future without having to restart.
rocky ivy
Yeah, like I said the problem is intermittent. Its no longer happening now. Just...
I am surprised I didn't see the part where you said it was (intermittent)
blazing lintel

Weird suspicion here, but what engine is it using when it spikes to 100% exactly?
regal hedge
@blazing lintel what do you mean engine?
blazing lintel
<@724085072856219739> what do you mean engine?
Right next to your util, there's a tab that displays what engine its using such as "GPU 0 - 3D"
regal hedge
It's using the same GPU engine.
My CPU is a Ryzen 9 7900x, GPU (while waiting for upgrade lol) is a GTX 1060 6GB
GPU 1 is Ryzen 9 onboard Radeon graphics
GPU 0 is my GTX 1060, it was using my GTX 1060 all times thats its been freaking out
blazing lintel
It's a lot more complex than just 3D and 2D in the traditional sense
Still, what I'm thinking is maybe it's reading 100% off the wrong engine sometimes, hence the crash and spike
regal hedge
This graph in task manager was like extremely spikey too obviously
But completely normal now even though I have the client open
blazing lintel
Interesting
Well, since it's intermittent, I guess you don't know any surefire way to replicate it?
regal hedge
I took a cell phone video of it let me upload that if that helps you with any ideas lol.
And yeah, no idea how to replicate it.
blazing lintel
I took a cell phone video of it let me upload that if that helps you with any id...
That'd probably help yeah
regal hedge
Couldn't screen record because it was freaking OBS out.
blazing lintel
Couldn't screen record because it was freaking OBS out.
Oh no definitely lmao
blazing lintel
Use DDU
Not the best idea if it's intermittent, at least until it can be replicated

Desktop windows manager uses a lot for me to
If the game does need full 100% usage
It’ll give some to desktop manager
blazing lintel
Desktop windows manager uses a lot for me to
DWM is kind of a catch-all term for whatever windows is doing actually
mild ridge
Like if the game is running fine
blazing lintel
It's basically it's redraw protocol
regal hedge
Just to be clear, its even while not in game, it just started happening during in game
mild ridge
If the application doesn’t need all the gpu
It’ll give to desktop manager
Whatever the shit is Calle
regal hedge
Hmm, cellphone video too high quality to upload lemme see what I can do
blazing lintel
DWM uses GPU, and when a game needs it, it just stops
blazing lintel
Hmm, cellphone video too high quality to upload lemme see what I can do
You can compress it or trim it
regal hedge
I have like 15 windows open right now, chrome, league, spotify, discord, signal, etc. and my DWM is using 3% of my GPU lol
blazing lintel
I have like 15 windows open right now, chrome, league, spotify, discord, signal...
Yeah it's just redraw lol, it just spikes sometimes due to windows being windows
regal hedge
sometimes? as you can see its oscillating between LoL and DWM being 100%
blazing lintel
sometimes? as you can see its oscillating between LoL and DWM being 100%
Not necessarily, task manager probably just can't read it accurately
Anyways that's definitely a DDU scenario @mild ridge is right
regal hedge
this the right dl for that ? https://www.guru3d.com/files-details/display-driver-uninstaller-download.html
blazing lintel
Yep
As for the nvidia drivers, grab some from their website and not Windows if you didn't know that
regal hedge
Yeah I have GeForce experience installed with the latest ones
blazing lintel
👌
regal hedge
Maybe the old Windows driver didn't get uninstalled and is being an ass or something and sticking around
regal hedge
Alright, ran DDU, hopefully the issue doesn't come up again, thanks for all the help @blazing lintel @mild ridge
mild ridge
Ofc
