PC Lag When Downloading

So I have noticed that my PC has been experiencing performance issues when I download. For example, today I was in a competitive game of CS:GO, and I was downloading an update for Fortnite. My friends were also doing the exact same thing, with no issues and less powerful PCs. My problem is I was noticing frequent FPS drops and an unstable and laggy feel to CS:GO. Pausing my download stopped this lag, so it is definitely related to that. As to the exact cause, I have no idea. Both games are on different SSDs, my CPU usage didn't go any higher than 80% and my CPU temperature didn't go above 80 degrees Celsius. I did notice the CPU turbo speed was dipping from it's max of 4.30Ghz though I assumed this is normal with how turbo works for a locked processor. Anyways... I am worried because I have noticed occasional PC freezes lately, both in games and on the desktop. I am not aware of any changes I have made, and have tried everything to fix it.

 

PC Specs:

Motherboard: ASUS ROG STRIX Z370-F GAMING

CPU: Intel Core i7 8700

Graphics Card: NVIDIA GeForce GTX 1080 Ti

RAM: Corsair Vengeance RGB Pro CMW16GX4M2C3000C15 16GB DDR4

SSD 1: Samsung SSD 970 EVO 500GB

SSD 2: Samsung SSD 860 EVO 2TB

 

Troubleshooting Steps Attempted:

  • Updating Windows 10 and all outdated drivers
  • Clean installing graphics driver with DDU
  • Updating BIOS
  • Monitoring PC temperatures

 

Any help would much be appreciated. Thanks in advance.

So it's because of my high download speeds that is causing it? Is there anything I can do to fix it or is this normal behavior?

that is normal behavior... you could try to use QOS if your router offer that and prioritise cs-go traffic...

 

Many years ago, while 100 mbit was the shizz top speed in our student network I tried to explain the ip traffic like a stream of water... 

Have a hose with 99% of your availble waterflow shoot out the water, then attach another hose which puts out the left over 1% ... then try to make one stream with those two hoses... you'll see the lower stream will bounce off... 

 

On TCP/IP traffic the behavior is likewise... when you run a download that saturates your connection to for example 80% you see all other web traffic becoming sluggish, dns requests when surfing, initial loading of the webpages etc...

And I’m supposed to smell that?

 

Because you have multiple ‘down’ streams - it can cause these lags / stutters. Especially because you say when you stop downloading it goes away.
