I have just upgraded my motherboard, CPU and RAM. Is there any benefit in reinstalling rf2 after this upgrade? Many thanks.
In a word, no. Whether you have any settings you've played with over time that may no longer be required and could provide a less enjoyable experience (probably visually mainly) might determine if you should try resetting all the settings - and renaming your entire Userdata folder and verifying rF2 files will take care of that. But chances are you're fine. The game won't be somehow tuned to what you had before.
