Unplayable stuttering and framerate drops since update (nothing to do with internet) (video proof)

Hello

Ever since the update I have unplayable stuttering, framerate drops, and frametime highs. This timing makes it extremely obvious that the update is what caused it (because I literally went from playing death match perfectly to having problems after the update). I also did not record any examples of this, but 1/3 times the menu will just lag out and crash when I open the game.

It is not a problem with my computer (at least not a general one) because I can play the finals and valorant with no problems and very high framerates. Also for the last year of cs2, and immediately before the update, I was able to play the game at like 300-400 fps consistently (drops to like 250 in water ancient, I barely notice, I'm "living the dream" normally).

It is not a problem with my internet because it still occurs in offline servers with bots (also because I have extremely fast internet that did not magically become bad after Valve's update lmao).

I have tried verifying integrity of game files. I have tried reinstalling and uninstalling the game.

Here is a playlist where I show what is happening across community death match servers (in NA and EU), valve official DM, valve official casual, and offline with bots (to prove it has nothing to do with internet).

Can anyone help me? I am at my wits end. I just want to play CS, hopefully without having to get a computer science degree to stop it from stuttering.
