While Battlefield 3 doesn’t have a built-in screenshot button, there are a few options for taking ingame screenshots.
The first option is from the console. First, press the tilde ( ` ) key. Then, type the command Screenshot.Render and hit Enter to take the screenshot. The screen will flash white briefly to show a screenshot was taken.
You can take another screenshot a little more quickly if you’ve already entered the Screenshot.Render command once before exiting the game. To take another, press tilde, the Up key, then Enter. Screenshots taken using Screenshot.Render are saved in this folder: C:\Users\%username%\Documents\Battlefield 3\Screenshots
A second option is to take a screenshot in windowed mode. If you’re in full-screen mode, press Alt + Enter to go to windowed mode. Next, press the Print Screen button. Finally, you’ll need to open a program such as Paint and choose Ctrl + V or Edit -> Paste to insert the screen shot, then save the image.
There are also a number of 3rd party programs that will allow you to take a screenshot with a simple key press. FRAPS has a free version that will let you take a screenshot simply by pressing the F10 key.
Great. Fraps – that is the only program I hear about. It looks to me as if a kid with a crayon drew it.
Also, you got to pay to take anything other then BMP..
I think it was programed in BASIC back in the DOS days.
