Is anyone else getting less FPS since the gun mettle update came out?

And im not talking about the new unoptimized maps like suijin which drops my fps to below 45
with some random lagspikes in between...

I noticed that even on other maps my fps drop below my frame cap of 66 which never happened before unless i was playing on a 32man instarespawn dustbowl server or some ♥♥♥♥ty orange server where you'll have all the players in one place sometimes.

Its not unplayable but i was thinking about finally getting a 120hz monitor so it would be really nice
if i could keep 120fps constantly which atm would be impossible unless i would completely ruin the looks of
the game.
I already disabled antialiasing and filtering completely which doesnt help much and half a year ago i had
no problem running it on max settings either ..

Im wondering if valve will/can do anything about that because i feel like im not the only one with this problem..

This is my system btw:

AMD Radeon HD 7970 (3072 MB)
Intel Core i5 2550K @ 3.6GHz
Kingston 16GB 1333Hz RAM
Samsung SSD 840 PRO Series


So i guess ill either have to wait for valve to do something or upgrade my systeam just to be able to play TF2
how i would like to..

And i have the feeling that even if they fix some stuff to make the game run better it wont be enough...
... stupid spaghetty code :(

Also, i was playing on doublecross earlier with only 8 players on each team and was able to stay at 120 fps
untill there where multiple people fighting on the bridge which dropped my fps to below 70 or something.. that definitly
didnt happen a year ago, not even on a full valve server.. im pretty sure that those skins are also causing some of those problems.
