I only have 21 fps total,how do i increase them?

By posting this is bug reports.

Omniary: fuck you anglerfish can't smell
Dr. Trialtrex21: how you know bitch
Omniary: it probably could smell you though
could probably smell your fucking dank ass nasty powersuit structure gel trog ass enslaved protein bullshit sloshing in your suit from a mile away

tl:dr, it's about as easy to increase your fps without tinkering with video settings as it is to download more ram.

Turn off vsync, antialiasing and anisotropic filtering, play in windowed mode, disable bump mapping, recode the game to get rid of FastText and FastExt altogether, or wait for a remake.

What do you mean by recode?

What do you mean by recode?

To put it in layman-accessible words:
SCP: Containment Breach is made in something called Blitz3D. There are several files, and each file has words that give instructions for the game. However, these files depend on two other groups of files, named FastText and FastExt. They each have useful extra functions, but I think they slow the game down.
By rewriting the words in the files, you could possibly make your own faster versions of the two groups of files, and it might increase your FPS.

I think you need to go to Options and lower your graphics settings or resolution.
