FPS issue with my map

[Mapham]

I have this weird fps problem with my map. In certain spots, if I move (not looking around), fps drops very noticeably. I have no clue where to start searching for the problem. Another weird thing is, that if I put budget panel on, the fps jumps to normal levels, also if i turn vsync off it solves the problem. But I will not play without vsync because without it, the image gets scattered while moving. Another reason is that changing my game options does not solve the problem itself.

Budget panel shows that something called Swan butters takes alot of resources constantly. Also toggling wireframe shows me the entire map, I am not sure is that what should happen with wireframe option.

The most weird thing is, that those fps drops do not happen when I am looking at large areas, it seems very random also. I have tried removing lights from the areas where this problem occurs but it does not help. My lightmap scale is 16, tried higher numbers but it did not help. I have used func_detail as much as I can. Nodraw texture everywhere players cant see, also does not help.

I did not use hint/skip brushes at all before, so I decided to try them. But the problem is not here either, because the fps drop happens regardless of removing stuff from being drawn. Also, the spot where fps starts to drop, has no fps issues at all while looking at opposite direction.

First, verify the intergrity of your game files (right-click game, properties, local files).

Restart steam, restart PC.

This seems like a RAM issue, try it with another game.

There are a lot of things that can cause an FPS drop. Do you have a leak? Did you compile with vvis? Is the console showing any errors?

Also that thing you see in the Showbudget panel is "Swap Buffers" (lol swan butters)
From the VDC

Swap buffers
A lot of time in Swap Buffers is usually a fillrate problem. Be sure to run full screen and at a lower resolution to test. You can also use mat_viewportscale to test if you are fillrate limited; watch for performance shooting up as the value decreases.
Here are some useful bindings for changing mat_viewportscale using the "[" and "]" keys:
bind "[" "incrementvar mat_viewportscale .1 1 -.1"
bind "]" "incrementvar mat_viewportscale .1 1 .1"
High fillrate can be caused by a number of things, but it's usually expensive materials that cover large amounts of screen space. Expensive materials include:
Water, especially water that overlaps over or under other expensive materials.
Fire, smoke or steam effects.
Glass or other transparent textures, especially with refraction.
Bump, normal-mapped, or specular (reflective) materials.
Any other material with complicated shader effects.
To solve fillrate problems, reduce the number of expensive materials in the scene by simplifying the materials themselves or reducing their number by removing geometry.

I didnt understand that fillrate stuff, what exactly i need to do to fix it?
Map has no leaks, i run with normal setting for all setup.

There are no fps issues with the game while playing on other maps.

Here is the compile information:
