Ultimate Flashpoint Mod was started in 2008 when I, the creator of UFM, wanted to showcase all of OFP's best content into one package. Here today, it has reached a humungous size, and continues to grow, as the cream of the crop of OFP content is integrated with it. It keeps getting better and better, folks. :)

2.6 ghz single core processor or better(Dual Core recommended for Windows Vista)
1 GB of RAM or more(2 GB for Vista)
256 MB ATI or Nvidia Graphics Card(7800GTX or X1950 or better for optimal experience)
At least 6 GB of free hard drive space

While Operation Flashpoint is not the best optimized game around, you can still get good performance with it. I run a GTX260 and I can force 16xQAA and 16xAF with no speed decrease whatsoever. I would recommend that you have at least 256MB of video RAM to keep crashes minimal, as this eats a lot of it. Also, please keep in mind that while you processor can be below 2.6 ghz, it will probably be laggier.

OFP Resistance 1.96 is REQUIRED to play this mod.
