FPS drop in new area "Containment"

@EA_Blueberry I'll check those out. But generally I don't have any FPS spikes drops or problems, mostly the game runs fine and smooth. But it is noticeable when I go into this one area on the map suddenly very significant drops start occuring... from my own personal experience mapping for Source (lots of CS) this did manifest much more like a specific map related problem as opposed to some global conflict which would affect things everywhere all the time. I have removed an autoexec config with a few console commands to see if that makes any difference, but pretty much all it has was this :

cl_drawmonitors 1
cl_forcepreload 1
mat_screen_blur_enabled 0
hud_setting_minimapRotate 1
hud_setting_pingAlpha "0.400000"
refresh 144
// fps_max 0
fps_max unlimited
r_drawtracers_firstperson "1" //set to 0 for no tracers on your bullets
mat_autoexposure_override_min_max "1" // is required to get the other auto exposure commands working
mat_autoexposure_max "1" // slightly lowered the exposure of the world
mat_autoexposure_min "0.9"
mat_autoexposure_speed "9" // Speed between the exposure changes
mat_autoexposure_uncap "0"
sprint_view_shake_style "1"
