I am posting here because it is quite obvious nobody reads the support section move it or lock it whatever im just posting this so hopefully the devs actually read it. The PS3 version is almost completely unplayable for me. The game drops to about 1 fps almost instantly after i start the game or it just flat out locks up all together. And not to mention that 1.05 completely disables all DLC. :brokencomputer: It really makes me sad too because the game itself is really fun but its so buggy. :cryvaultboy:
As a PS3 user who has played the DLC, I can confirm it works fine.
Others had the same issue as yourself and were instructed to delete anything FONV related from your "Game Data" folder. Boot up the game to download the latest patch, THEN download and install the DLC. If the dlc is installed before the patch, that is what causes the problem.
There is still however, the issue of DLC locales being mixed(e.g. Canadian Honest Hearts and US Mercenary Pack do not mix) but i believe that is being addressed in the upcoming patch.
