you have r_lod 2 used twice. No worries, I'll change it.
EDIT: also, why did you customize the surround sound settings

snd_rear_headphone_position 135.0

EDIT2: there are some functions that should be customized by the user only and don't add any frames

tf_dingalingaling "1"                
tf_dingaling_volume "1.25"           
tf_dingaling_wav_override "" 

This is my interpretation

I have a warning placed on the front of the main post. Anyone with multicore should be fine.
EDIT: I've added and changed some things in your config

Added your CFG, great job at making the best config available.

8/11/15 UPDATE!!!
- R4NDOM's config replaces Rhapsody's config
- Minor Cleanup
- Launch Options updated

I've been tinkering around with multiple configs and can't get any better than Comanglia. If your config works better I'd love to add it to the pack.

M0re shoves in many obsolete cvars. For example, he disables bloom then lowers all bloom settings. If bloom is disabled why modify bloom at all?.

EDIT: I tested my modified Rhapsody vs Comanglia and was 1 frame short

I tested both configs
Comanglia

2639 frames 33.213 seconds 79.46 fps (12.59 ms/f) 3.730 fps variability

Tweaked Rhapsody

2639 frames 33.882 seconds 77.89 fps (12.84 ms/f) 3.217 fps variability

Damnit, I'm down by 2 fps

I'm having doubts myself, go for it R4ndom.

Comments like that make me feel warm inside :D You're Welcome!

Stop reviving dead posts. There is a much higher skill ceiling in this game, Warsow. Also, it's free.

Not quite, I've done a bit of particle work in my pack. Strangely enough some custom particles and scripts function fine in sv_pure 1, will test the boundaries of this.

Explosion particle eotl_pyro_pool_explosion_flash is not available during year 2013 (the year that benchmark1.dem was made). Thoroughly filling the screen with red X's.
The only obvious fix for this is to use a different benchmarking demo. Since I have no experience in benchmarking, I'm going rely on you guys to help me through this.

good point

after a little addition from m0re I got a pretty shitty looking TF2. ouch...

You can run any other autoexec.cfg file, but for the extra features you would need to add "exec autoexec2.cfg"
I've changed Rhapsody's config slightly, it should run most if not all functions found in Comanglia cfg and others.

set your game to 1920x1080, all menus and utilities will run at high resolution while the gameplay runs at half that.
EDIT: If you would prefer to use a constant resolution change to mat_viewportscale 1
