You can make config files based on the map name, e.g.: cp_badlands.cfg, that config will be executed when that map is loaded.

There are a couple of reasons the sound quality could suck:

1. The headphones are operating using the "headset (HSP)" profile instead of the hifi headphones profile (A2DP). In this mode, audio quality will be that of an old fashioned phone call. This can sometimes be prevented by disabling the bluetooth microphone device of your headphones in windows, if they have one.
   
2. The headphones only support lower bitrate versions of the SBC codec. This will sound like a bad MP3. If your headphones are old, this is probably it.
   
3. The headphones are crap

Bluetooth audio can sound very good if:

1. The headphones support a modern audio codec at a high enough bitrate: high bitrate SBC, AptX, AAC, LDAC. . Anything from a reputable brand made in the last few years will support at least high bitrate SBC (372Kbit max).
   
2. Your system supports these bluetooth codecs. Windows 10 can use SBC and AptX.
   
3. There are a few great bluetooth headphones available and a ton of crap. Some good ones: Bose QC35 (SBC + AAC), Sony 1000x (SBC, AAC, AptX, LDAC) and the Sennheiser Momentum (SBC + AptX).

As far as I know, the batch that I was part of in November 2012 was the last one, so I'm not very surprised many of those people are no longer active.
Apart from those batches, they've more recently given discoverers of critical bugs special items.

Topic is called i61 feedback, so the following is not all specifically meant for Essentials.tf. After doing production for i49, i52, i55 and i58, it was both weird and relaxing not to be involved this time :)

+ HUD
+ In-game framerate (didn't look like 60FPS all the time, but overall smooth and good enough)
+ Warhuryeah, great balance between insightful commentary and taking the piss out of the teams and players if the matches got a little boring or when bad plays were made.
+ Stream encoding quality
+ Splitscreen rollouts and sniper action
+ Quality of casted matches, close games
+ Production quality.
+ Player cams, instantly linked to the in-game observer, very cool.
+ @TF2Essentials twitter and Facebook was alright
+ Comp.tf
+ b4nny giving the LAN just a sprinkle of intercontinental rivalry and lifting SVIFT to 7's level

- Online servers at LAN for the first day again.
- No STVs.
- In-game camera missing too many key moments. Weird considering the experienced observers.
- Audio isssues. Picking up stage music, pitch and speed changes.
- No interviews
- No team reaction shots, no roaming camera, just static shots.
- Little connection to the LAN, just some shots of the crowd in front of the screen.
- Picture-in-picture too small, especially the first day.
- Side-by-side view hurt my eyes sometimes, especially with two snipers zoomed in and looking around.
- Lack of hype leading up to the event
- Lack of written coverage before and during the event
- Intro and outro movie felt underwhelming compared to previous editions
- Teamfortress.tv twitch not auto-hosting Essentials.tf
- Teamfortress.tv in general regarding i61

Overall very impressed by the Essentials.tf production, thanks a lot!

The Picture-in-Picture is for ants

It's not about splitting the community, it's about who shows up and actually does the work. There's coverage of i61 because essentials.tf is making it happen.

No client-side device or setting can fix the terrible internet situation you are in. Only by replacing the camp router with a device that does proper QoS and bufferbloat management can you hope to share a connection with 20 people without lagging.

Is tethering your phone an option?

G-sync is great, just overpriced.

Like GentlemanJon says, I had to take it down due to unpatched security holes in unmaintained plugins. Also lots of deprecated stuff broke after upgrading the machine that hosted it to PHP 7.
The content is safe of course, database backups and files are still there.

Powerline adapters are garbage.

Perhaps you've added an electrically noisy appliance, or maybe a neighbor got one of those things as well and it's leaking into your powerline, or maybe you just have some random electrical interference from somewhere. There's a bunch of reasons why these things can start to suck even more than they're supposed to.

Try a real ethernet connection if you can, use 5Ghz wifi if you can't.

You said you were connected through ethernet, did you really mean ethernet -> powerline -> ethernet?

Your ping is already spiking to your local router, so I suspect that is the reason of your poor ping. Have you power cycled it yet?
