download causes high CPU usage.

[BOT Retard]

So I'm currently downloading something on my PC, it is not using the internet. My CPU usage is at 99 when download it and my temps are at 190-200F and I have to downclock my CPU in the processor power management so it's running at 4GHz instead of 4.6 GHz. Why is it using my CPU to download? It's indeed using my hard drive because that's always at 99 or 100 disk usage. But why my CPU? What does my CPU have that my hard disk can't do by itself? Because I find it pointless that my CPU is even needed during this download. I have the i7 4790K.

Well, maybe then there were issues with RAM and swap file in your system? See, as people prevously told you, OS drive shouldn't be THAT full, I mean 3 GB spare is a joke nowadays. There might be that downloaded files were located in RAM of your computer to allow smoother decompression but RAM space was insufficient so OS tried to use swap file. Normally it would use faster SSD drive but due to the fact it was almost full, much slower HDD was used for swap file, thus decreasing the system performance even more. No surprise with all that IO operations with high latency your PC was almost stopped with relativly simple task of downloading a file.

PageFile doesn't work like that; the PageFile space is already set aside on the OS drive. It doesn't move on to then use a different drive like you are suggesting.

No OS Drive should be near full, ever. Always allow 30+GB of free space on OS Drive.

No wonder your PC slows to a crawl.

What do you mean by OS drive ???

[Bad 💀 Motha]

The C drive, the drive the OS is installed on to.

OS = operating system

I'm glad that you took the time to respond, but to be fair I'm aware on how computers work. I just found it very odd that my CPU was practically at full usage and it was stressing the hell out of my CPU. It's never really done that before. It ofc uses my CPU. The CPU is the brain of the computer. The CPU is used for almost everything. But I usually get half usage when downloading huge files. Not full on 99-100 percent usage.

If you know how computer works you should know even at 100% load you should never hit 90°C. First fix your cooling problem, then your low space on your OS drive and then you should check if your av cost a lot while downloading

Old thread aside

High download connection speeds need a decent CPU to not peg out, when you go for Gigabit tier speeds the CPU is going to play a part in maintaining those speeds not just what the SSD/HDD etc is capable of.

Most of the comments in this thread are clueless.

I was doing a 10MB/s download of a new game and steam_osx was consistently using between 50% - 100% of a core. I have a new, high-end MacBook Pro with an SSD. The usage was bad enough that the download alone got my fans spinning loudly.

This is ridiculous. Downloading a file and writing to an SSD should require very little CPU power at all. Even if it is decompressing as it goes, which doesn't appear to be the case, this is incredibly inefficient and should be remedied.

read my first reply

steam decompresses files while downloading them

It's normal. If you want a game to download faster, once you start a game download, go find something else to so. Allow that PC to be idle from you doing any other stuff on it while it downloads your games. This allows it do be done quicker, using whatever it needs for cpu and your ISP connection, plus drive read and write...

Anything running Mac OS is also a bad example as Macs are junk systems to begin with. IDK what games you'd even download on a Mac since no major games are really even made for Mac since devs know Apple products are a joke when comes to gaming.

[Bob the Boomer]

Probably due to compression or decompression algorithms, or your HDD free space is below %20 *if* using NTFS file system, not sure what MAC uses for a file system

So I had this similar problem and I have an i7 10700k and I was downloading COD BO3 and all of a sudden my pc kept crashing and it kept crashing due to 100% utilization as soon as my computer would boot into windows and start stearn, it was also hitting 5.0 Ghz and then BSOD but I saw it was also using the network at 100% 1GB, so once I saw the issue I paused the download and it would bring everything down and back to normal utilization. So if you are having this issue just pause the download and then once it drops the utilization just resume and repeat as needed.

Thats not exactly a solution...

High Bandwidth downloads tend to use a decent amount of CPU usage, if other things are going on in the background that could worsen it.. There is obviously something wrong with some aspect of your PC if merely installing a game kills it.

Check for BIOS updates, and see if there is an updated network driver for your NIC.

If you are running into issues simply by installing something, you either have temp issues, RAM issues, SSD/HDD issues or even Power issues.

You should use the program WhoCrashed to analyze the crash dump and see what EXACTLY caused the blue screen and paste us the results.

if high cpu usage causes a crash, its often unstable oc or bios needs an update so it gives a voltage bump at load

Well, of course a CPU usage is going to be high.

The CPU needs to process the information downloaded and storing it. Without a CPU, there is no working PC.

My 9900K goes to 70-80% usage when I download something on Steam via 1000Mbps (~110-120MBps)
