I suggest you turn the following features OFF:

This mod should help with slower quad-cores (slightly) and slower GPU's (more so), but that is all. Note: You still need a quad core CPU, 4GB RAM, and a 64bit OS. Highly speculative, but cards such as NVIDIA GT 540 / GTX 450 / GT 630 / GT 740, ATI Radeon HD 5800/5700, Intel HD 4000/4500, and any similarly low-spec mobile versions (460M, 540M, 630M, etc) may run the game at playable FPS with this mod. In extremely limited testing using otherwise the same graphical settings, I've achieved these results: If you have a graphics card that is at, slightly above, or slightly below the minimum requirements - this is for you! If you have a lower-end graphics card I'd be happy if you could help me test this. This mod isn't meant to look pretty, just make the game playable smoothly for those who couldn't do so otherwise. Please keep in mind that while playing the game the ugliness of the textures will be much less jarring and personally I feel like you get used to them pretty quick. This mod reduces texture quality on many objects throughout the world. This version of the mod will only work with FC4 game version 1.5 If it doesn't work, just swap back to original files and all will be well.

There are no gameplay changes, but I don't know how Uplay handles multiplayer stuff. I've been working on a mod to enable lower-end systems to play FC4, and here it is in all its beta version glory.
