How to switch the HUD view in tf2

My first piece of advice would be to go into the video options and enable Multicore Processing. It's been my experience that this is disabled by default, and enabling it usually results in a performance boost. Despite being in the video settings, this is actually a CPU option.

My second piece of advice would be to make sure you have recent nVidia drivers installed.

Note: My system is a Core 2 Quad 6600 with an nVidia GT240 512MB GDDR5, so yours should outperform mine in anything that's not using a lot of CPU cores.

Here is an instruction on how to create a server and put bots on it:

1. Make sure you have the port 27015 accessible for connections.
   ^{How? Look here.}
2. Open the game console.
   ^{How? Options⇨Keyboard⇨Advanced...⇨Enable developer console. Press ~ / ` to open the console at any time.}
3. Type sv_lan 0 if you want the game to be public, or sv_lan 1 for LAN only.
   ^{Public server is recommended}
4. Type map <mapname>, replacing <mapname> with the name of the map you want to play.
   ^{Or press the [+] to the right of BROWSE SERVERS in main menu instead.}
5. If the server is public and you don't want anyone to intrude, you can set a password:
   Type sv_password <pass>, replacing <pass> with some simple password.
   _{(e.g. sv_password 1234)}
6. Set the bot difficulty: tf_bot_difficulty <x>, where <x> is from 0 (the easiest) to 3.
   ^{(e.g. tf_bot_difficulty 0)}
7. Add bots: tf_bot_add <team> <class>
   <team>: red | blue
   <class>: scout | soldier | pyro | demoman | heavyweapons | engineer | medic | sniper | spy
   ^{(e.g. tf_bot_add blue heavyweapons)}
   To remove all bots: tf_bot_kick all

Here are some ways for your friend to connect. If one fails, try the next one.

• Join the game via Steam.
  ^{In Steam Friends list press ▼ and Join Game.}
• In console: connect <ip>:27015, where <ip> is your (server's) IP address.
  ^{(e.g. connect 11.22.33.44:27015)}
• Try the same thing with your (server's) local IP address (find it in Windows/Linux)

If nothing works, see the step 1 of server creation instruction.
