So I've been having this problem for several months now. I open up TF2, hit up the server browser, head over to the internet tab to find some random pub, and it takes 10 minutes to load up 50 servers of any given game type.

Now, it is faster if I take off a map filter, but I usually just only use "koth" or "cp", and don't specify any further than that. and it takes ages. Even without a ping limit, server not full unchecked, etc.

I know a lot of people would read this and think "Must be your internet connection". Well, it's not. My friend who comes over fairly often never has this problem with his computer.

Things I've tried
1) Re-install TF2
2) Re-install Steam
3) OS (Win7) is freshly installed
3a) Drivers are all up to date
4) Delete master browser list
5) Added exception for hl2.exe to real-time protection
6) Flushed DNS cache

Any ideas would be really appreciated. I don't have time to play mixes/competitive format at all right now, so occasional pubbing being possible would be great.
