My connection is 100Mbps. So I got up to 13MB/sec max. Mostly 10-11MB/sec. Started downloading last night. Was done by this morning. Actually it was probably done in about two hours but I left my PC on all night so it could download anything else it needs.

I feel ya, I'm only getting 1.5 MB/s. Oh well only another 8 hours to go.

5.1-6.5MB/s which is nowhere near full 1Gbit/s but still okay.
Hmm... download speed went up to about 110Mb/s for a minute then went down to 7-ish Mb/s again which means it's just GOG CDNs are overloaded with a lot of people preloading the stuff.

My DL speed is abysmal. It must be from everyone downloading Cyberpunk right now. I get over 850MB/s Speeds. on steam I download at 115MB/s but on GOG I am sitting at 0.3MB/s while pre loading Cyberpunk. but just two weeks ago I downloaded Witcher 3 and I was getting about 20-30MB/s so... I will lose my mind if I will have 0.3MB/s at 4PM on a 40GB day one patch...
Maybe I will just get it on steam so I can avoid the backlogged servers. I wont even get to play until the end of thursday night!!

850 MegaBYTES per second? Are you sure you didn't mix MBits/s and MBytes/s? 115 MegaBytes/s sounds like a Gigabit connection to me, 850 MegaBytes/s must be something close to 10 Gigabit/s which I wish I would have but never heard anyone having these speeds at home. :) Plus 850 Megabytes/s will be a challenge for your typical SSD, let alone HDDs.

I get 1GB download speed - that and I have the Samsung Evo 970 PRO so my SSD can handle it I think lol.

UPDATE: It would appear that for whatever reason - my wife was streaming on twitch and once she turned it off my speeds went from 0.3MB/s to 97MB/s Download speed on GOG.

It is still strange that it was so negatively effected since I tested my download speed on steam and I was getting over 100MB/s before she turned off her stream, so maybe there is something weird with the GOG servers connecting to a network thats already under load? IDK - All I know is it is finally done preloading and I hope that I dont have the same issue on wednesday when we need to install that 70GB patch haha

Sure, NVMe drives would handle such datarates (yours would handle about 2000MB/s depending on the actual writepattern) but still you would also need a 10Gbit/s NIC which would be pretty uncommon, most likely a 10Gbits/s switch (or you are directly connected to your router with such an interface) and then we would talk about if you own a AMD or Intel system because how Intel works with the NVMe being connected to the chipset which would also provide the PCIe lanes for the 10Gbit/s NIC, you would most likely not get this throughput via the network directly to the SSD. Intel has a quite limited amount of PCIe lanes which are reserved for the PCIe x16 interface of the gfxcard and the rest is handled via the DMI3.0 interface down to the chipset which would be the bottleneck in this scenario. On the most recent AMD systems it would depend on the actual setup of the system.

So, I guess you mixed megabit and megabyte per second. ;) Not that it's important, over 100 megabyte per second is plenty of throughput and quite topnotch on the consumerlevel,

Not strange, if she was streaming I'll hazard broadcasting? Then you're seeing upload bandwidth saturation. Meaning only some of your upload requests were getting out. Another possibility is that you're using traffic shaping on your router with a priority for video. In which case, streaming of any kind will be granted priority over anything else.

Downloaded it today with a speed around 45 - 49 MByte/sec, went very fast.

Slow to me. 20-30 MB/s (160-240 Mbps). Servers seems to be overloaded.
