nissa: - why didn't GOG downloader auto-update itself, like it usually does (if I recall correctly) ?
it will be added later on, with the next major version ready. Right now you can minimize it to tray and click "Check for update" manually.
nissa: - why are the downloads so sloooooooooow now ? It makes me cringe to have to wait 30 minutes for a 1 GB download (Arcanum), expecting the Witcher 2 (which I have pre-ordered) to be much more consequential size.
well it shouldn't be like that, majority of users who tried the new downloader report a noticeable increase of speed... By default, the downloader should use 6 simultaneous threads to download every file (while web browsers use just 1) and you can edit this value via Options screen. Now, depending on your connection, this might be not enough or actually too much. In theory starting from 2 connections and above you should see some increase of download speed, however at some value this might start backifing due to the number of concurrent connections openned, so don't get tempted to set it to max if 6 is causing your download speed to decrease.
