Reinstalling my Steam library revealed that I've been limiting myself to 100Mbps on all my wired connection since the cable connecting my gigabit switch to my router(itself with 1Gbps internet connection) was apparently only capable of 100Mbps. Oops, that's probably been going for a couple of months. Shows how much I use my desktop computer I guess. At least the WiFi wasn't affected.
