Beware of optimization mods, they rarely do as they advertise & worse case they do nothing at all. I've been saying it since this game first came out, modding before a game is content complete is an uphill battle and you will likely run into more frustration then anything else.

Personally, the last thing I want to do when firing up the game is perform IT work. But I get it, some people just can't handle vanilla games and need to change the color of onion flowers from purple to magenta or whatever else is worth the risk to them.
