Thanks to Better FPS (included in this collection!), you can improve the performance of your game simply by replacing a file. Here's how it's done:

- locate your 'Project Zomboid' installation folder (by default should be something like: "C:\Program Files (x86)\Steam\steamapps\common\ProjectZomboid")

- open the "\zombie\iso" folder

- in another window open the mod folder (by default should be: "C:\Program Files (x86)\Steam\steamapps\workshop\content\108600\3022543997\mods\BetterFPS\media\")

- select the most relevant folder for you config:
* \PotatoPC\ if you use a resolution lower than 1080p
* \1080p\ if your use a 1080p resolution
* \4k\ if you use a resolution bigger than 1080p

* \Original\ is a recompiled version of the original file

Inside each folder there is another folder \zombie\iso\

- copy this folder (or the content)

- replace the existing folder (or file) from Project Zomboid

ex:
replace "C:\Program Files (x86)\Steam\steamapps\common\ProjectZomboid\zombie"
with "C:\Program Files (x86)\Steam\steamapps\workshop\content\108600\3022543997\mods\BetterFPS\media\1080p\zombie"

This will overwrite the original file with patched one

Done!

The mod is included in this list, so you'll have those files already waiting for you. You will still need to replace them yourself - be sure to choose the right one for your resolution!
