SLOW Steam Updates

[GuardianGR00T]

I wasn't able to time my download of Icarus yesterday, as I was busy, but today it has a 1.2GB update that has already taken 15 minutes and is estimated to be finished in another 25. My internet speeds average anywhere from 925-950 Mbps and I'm using ethernet, so I know it's not an internet issue.
I've cleared the download cache and I don't have a limit set. What else should I check?
Is there something I'm overlooking here?
Please help, I'm bored out of my mind and frustrated with this lol.

What part is slow? Downloading, or applying the update?

[GuardianGR00T]

Applying the update seems to be much slower than downloading.

[Cathulhu]

Then it is solely an issue with your computer, not your network.

[GuardianGR00T]

Well, yes, lol, I've ruled out it being a network problem. I just need to figure out what I have to do with my PC to fix it.

[Cathulhu]

Depends on where the bottleneck is. Either the CPU, the drive the game is being patched on, or the connection in between.

Updating games is a IO heavy task.

[GuardianGR00T]

The CPU is an i7-8700k, the drive it's updating on is almost full though. Could that be the problem? It still has plenty of GBs for the game's update, but how much should you have free when updating?

[GuardianGR00T]

nullable, the problem is that I do have a fast PC. The updates didn't use to take this long; therefore, it is a problem. One that I would like to fix.
The only real updates that my PC needs are a better graphics card, and a heftier amount of space for my main HDD, which I am working to acquire.

[Cathulhu]

Yes, a full drive can be a problem.
You should have about 2-3 times the game size as free space for the update process.

SSDs also perform slower when almost full, so, for optimal performance, clear up some space.

I'm not the best with technical terms lol, sorry. I try though.
I know that with some games it's like that, as it is with ESO, the updates took forever even when my games were quick to download. It's been happening with more than just this one game, but only with my steam ones. EA, Epic, and just browser downloads have been fine. (And yes, I do uninstall them when I'm done with them lol)
I'm uninstalling a few large games that I don't see myself playing any time soon to see if that can help. Thank you both for the answers, at least I'm not running in blind anymore!

Your updates ofr game are limited by your disk speed or cpu

Generally speaking, adding a whitelist in your anti-virus for any steam directories and libraries will improve update speeds, as anti-virus generally is the largest hold up

I'll be sure to remember this, thank you!
