Getting engaged

mat_phong 0
r_worldlights 0
r_pixelfog 1

those will help the most, and already in my 2 FPS configs.

Unknown command "mat_shadowstate"
Unknown command "mat_debugdepthmode"
Unknown command "mat_debugdepthval"
Unknown command "mat_debugdepthvalmax"
Unknown command "cpu_frequency_monitoring"

just removed all of those

Unknown command "cl_forcepreload"
I double checked my stability and quality pc one and both have this command removed not sure how you're still getting this to show up.

Personally i hated the circle effect 0 creates around the player, that any beyond the blurryness of the toaster config the 2nd most common reason people added me to fix stuff with the toaster config was about the circle effect 0 creates around the player.

That and the fps difference is negligible just like
mat_filterlightmaps 0/1
mat_filtertextures 0/1

don't affect performance for 99% of users most would prefer them set to 1

-edit-
for those of you having issues with the new configs try my old stability one here

r_avglightmap 
r_lightcache_numambientsamples

removed most/all sv_cheat commands

mat_disable_d3d9ex
cl_forcepreload
net_queue_trace 0

removed above needless commands

mat_antialias 1

is now commented out

mat_picmip -1 changed to 2
mat_colcorrection_disableentities 0 changed to 1

I couldn't recreate this issue on 2 machines
Build 1
i5-4670k
R9 270x

Build 2
i7-4790k
R9 390

I tried all dxlevels and tried with and without transparent viewmodels still haven't had this issue.

-edit-
while attempting to find what's wrong with bleed/fire effect I notice that mat_viewportscale is no longer limited to .5 - 1

http://images.akamai.steamusercontent.com/ugc/404560951918458825/44A56D797958DD2BC62EF73D6FC8DC4C6D8A028F/

value is .01

still doesn't effect fps for 99% of users just thought it was interesting. mat_viewporscale is still limited to 1 at the max but the minimum seems to be 0 now.

that's odd

I use the overlay and I'm not getting that issue

actually the only time I ever had that issue was when I wasn't using -nod3d9ex in launch options

glow_outline_effect_enable 0/1 (same one for the cart and weapon drops)

-dxlevel ?

and this is after my update correct?

after testing for awhile I can't seem to fix this, maybe the hotfix update did it.

mat_filterlightmaps 0
mat_filtertextures 0     //OPTIONAL
mat_specular 0
mat_trilinear 0

this is a bit uncalled for, when I see a new config that's based off mine I don't expect much beyond 3 to 4 changes and maybe some formatting. My post was more about, hey you should reconsider a few things, and remove redundancies.

Also it's not like I make money off my configs, I'm not bothered that you're making one.
I also saved you some time on the eventual "how does this differ from the config you based it off of" question.

from what I can see

things you've changed

removed a lot of comment sections
rate 60000 (removed from good connection settings and no replacement)
dsp_slow_cpu 0 (I had 1)
mat_queue_mode -2 (I have -1 not sure why you'd switch to "legacy default" but ok)
mat_reducefillrate (you flat out removed this command which does boost fps when set to 1)

mat_filterlightmaps 0
mat_filtertextures 0     //OPTIONAL
mat_specular 0
mat_trilinear 0

^ I had 1 for all of these, also you have these in here twice you have the original ones I put in and you pasted these to the bottom

-edit-
There's a couple more differences since I updated my config just a few hours ago, but I didn't expect to find my most up to date one within yours

removed

added

tf_scoreboard_ping_as_text 1

also added, removed a couple redundant lines as well. Also beginning the search for which command is causing the black props in demos/local servers. I know the command is tied to sv_cheats though.

-edit-
Updated date of last update
also changed
mat_antialias 0 to 1
and
mat_forceaniso 0 to 1
both should be set to 1 now.

Honestly when I used 2 monitors and trying to play TF2 I usually disable the 2nd monitor as I always seemed to have weird fps drops because of it.

Just pick which monitor you want to use you have a 16:9 and a 4:3.
4:3 you'll have more fps but have narrower view
you could use a 4:3 res on the 16:9 monitor as well instead of using the square monitor.

Also I use a slightly different version for my tastes, but it's most similar to this one https://dl.dropboxusercontent.com/u/92187841/gfx.cfg

Old bench mark I did

basically the actual resolution doesn't matter, the aspect ratio does due to it's impact on your FOV

so 4:3 = Higher FPS ; Lower FOV
16:10 = Middle Ground
16:9 = Lower FPS ; Higher FOV

dehumidifier if you want to spend a bit

you might want to clean the mousepad (look up some youtube videos)

try new mouse feet.

All are based off the same panel though the newer ones have different options based on vibrancy and Black equalizer. Which typically make true color quality worse though you may prefer how they look.

just to clarify the 2420T has an older panel that wasn't as good as the one introduced in the TE model. The TE model has the same panel as the 2430T and 2420Z.
