I suspect most of the issues with GOG Downloader, were either related to using an older version or people using it when the GOG server(s) was heavily impacted by a sale. Or using it, because the GUI was at least low on resources, while using other memory intensive apps. This would be especially so, if GD was not multi-thread aware.
The only time I ever had an issue with it, was because of slow server responses.
I just had to stop and try again later.
Perhaps Galaxy deals better than that or is just better at disguising or notifying about it ... don't know.
What I do know for me, is that Galaxy is crap, and browser links can be troublesome, certainly without using a third party app that allows resuming and queuing and has at least some checking better than the default browser downloader. The irony, when GOG already had something suitable, to have to use a third party option, is staggering.
GOG had two great quality options for downloading the games we bought (depending on your perspective). They have now removed one, in favor of the other, despite how it impacts many of us. They have lost touch with doing the right thing, and believe in ramming what they want down out throats. I have been defending them for ages, because they were maintaining the choices. Now I have to suck eggs, because I have been proved wrong about them. In short, they are not the great store I thought they were, and currently I am going into damage control, for what I see is the inevitable end.
@GameRager - I don't need to provide proof, enough logic over actions and what I know about software and hardware is enough evidence. If GOG have something to counter that, then why don't they do it? That alone speaks volumes.
Even the recent evidence above by MarkoH01 speaks for itself.
Disabling the GOG Downloader did not have to happen, it was purely a choice reason, that is based on Galaxy at the very least, but which I personally believe extends beyond that.
