I cannot find issue on my side eighter. I'm trying to download 24GB Croc from GOG now. Download was for a while 6MB/s but for hour now stays still at 1,7MB/s. Tested on Steam - 450MB/s Smite 2 (18GB downloaded and installed in 4,5min... Meanwhile Croc at 7,42 GB after couple hours and "expected time" is still at around 2h 13min... Check restrictions in Galaxy - disabled. Check in task manager - default settings (no prio, no restriction on processes). What caught my eye. Task Manager reports network usage by Galaxy at 12-17Mbps (/8=2-3MBps). Where that 0,3-1,3MB goes? I understand background processes but everything here doesn't make any sense. Usage double the download speed and both at level i cannot understand and accept. I'm not paying for 1Gbps internet where everything works totally fine to accept 1,7MBps on Galaxy download. I've started to look for gog games as i support they way with licensing but damn... If that is how it will be and i will be waiting so damn long or have to look around to download it someway else than their app - i won't check anymore that shop. It has to be addressed and fixed.

I have the same problem, and to be clear, this is an OLD problem.

I have both GOG and Steam, and a 200 mbps connection. Steam downloads at around 60-120 on average.

I'm downloading a game now through GOG Galaxy, and it caps at around 5 mb/s, which is ridiculous.

As far as I can remember, this has been an issue with Galaxy for a long time. I can remember researching the same issue last year. As always, my default setting is no bandwith limit. If anyone has a solution, I'd love to hear it.

Same here, I tried several "solutions" (manual inbound firwall permission for GOG, Download Limit = 999999999999999 MB/s). From then the the download speed rises SOMETIMES for a few seconds up to 5 MB/s, just to melt down again to approx. 1,6 MB/s.

Seems GOG is saving a lot of money by keeping server costs low...

I learned my lesson, I'll head back to Steam even on titles which are a bit more expensive.

I've checked and, apparently, the download speed is actually good, but the client downloads in bursts of a 1-2 seconds at a very high speed (>80 MB/s) and then does not use network at all for another 5-7 seconds. The average comes out at 1.7 MB/s. The CPU usage is constantly high.

It seems the client is just terribly optimised (single-threaded possibly?) and simply cannot process what it downloaded quickly enough.

Steam displays its download speeds as megabits/second, while i think GOG Galaxy displays them as megabytes/second.

Do you mean Galaxy caps at 5 megabytes/seconds, which is the same as 40 megabits/seconds? Just making sure you are not comparing apples to oranges.
