Screens:
I wish I could get some screens in a forest scenario! But they all seem to be broken by the new version. View them at higher res for full effect.

Installation process
Extract the zip to the Overgrowth/Data/GLSL/ folder (If you installed from Steam, this is /Steam/SteamApps/common/Overgrowth/Data/GLSL/). You're done!
You used to need to change some values to fit your screen resolution, but as of alpha 210 it's unnecessary due to the updated shaders.
Customisation
In the same post.frag file as before, you can turn on or off Ambient Occlusion, Depth of Field, and Bokeh. Bokeh is off by default as of 22/11/15 because it's made redundant by the lovely HDR bloom.
You can also change the strength of the Depth of Field.
If the game is slow, first try turning off the blur's depth test. This is often unnoticeable when off so you can still have to full experience of the shaders without them. After that, try setting DOF and SSAO quality to 1 or reducing the "SSAO_FAR" parameter. If it is still running slowly, turn off either DOF or SSAO. If it still runs slowly, you'll need a better GPU to run this shader pack
Bugs
This mod has been tested on a Xubuntu machine with an R9 270 and Intel 4670 CPU. Often different graphics cards and operating systems give different errors;
I do not have access to any nVidia cards or Windows/Mac machines. Therefore if you encounter an error, please tell me your GPU, OS and exactly what the error says.
I will do my best to fix all problems
My wish is granted. I am getting these error for the post.frag:
