Hello @ozone89, per "Changed download throttling setting to be a custom value in Kbps" in the 2020-09-11 Steam client beta update, this request has been implemented.
@kisak-valve a nit/complaint: the divider used in your UI to go from kbps to mbps is 1000, while the real divider is 1024.
Nothing extracted yet.
Some countries (helloooo, Italy!) have lines whose speed are not suitable for tiered limits, especially when dealing with lower speeds.
In my case: I have a 4Mbps line, so the nearest tier would be 512KB/s, which is the exact limit of my line!
(512*8 = 4096)
However, if I was to set the immediate lower tier, I'd have 256KB/s, which is too low (In my case, I'd settle for something in between)(scratch this part, just received the latest update that added an intermediate option. the case remains, though)
What i suggest is to add an optional text field so that users may input the desired limit.
(a feature any download manager have since years!)
