Some downloads slow my pc, some don't

Hi,

I've been struggling with this issue for a while. When I download a game through steam or battle.net it cripples my pc but with the origin client in doesn't. I have 250gb samsung 970pro as boot drive, an older crucial 250gb I now use for games and a 3tb WD green HDD. I usually set the clients on the 970 pro and then download the game to crusial ssd. Now, at first I thought the issue might be that somehow the steam client is choking the 970pro. So I set both the client and the game itself on the crusial ssd. Same thing happens. Tried the HDD as well for good measure, same thing. And it's not like my cpu or memory are slacking either. I run a 3600x and 16gb 3200mh ram. During downloads my cpu is at 40-50%. And none of my disks seem go over 10 % usage. But now when I download from the origin client it's the opposite. Now the cpu is at 10% and the disk is at 90-100% and my pc is still working just fine.

It's the weirdest thing ever so I hope somebody here might have a clue to what going on.

Most games nowadays are distributed compressed, so get decompressed before writing to disk. That's CPU intensive which is why the CPU is at 50%, and you're essentially CPU-bottlenecked. Others aren't.

But how can I be bottlenecked when my cpu is at only 50%?

(edit) Okay so it got weirder. Just started the same steam download again. Pc is working just fine. I'm so confused.

Same as usual with CPUs with many cores, the decompression process can't make use of more than X threads and whatever extra you have just sits unused. 

 

An LTT video actually recently mentioned that, showing a game install and saying their gigabit internet connection is of no use in that case since the CPU just can't decompress fast enough.
