FBX Game Recorder 

Create high-definition recordings of gameplay on a computer by running the dedicated application as a background program. It uses the hardware acceleration on NVidia and AMD cards, and Intel CPUs to optimize speed and avoid lags and freezes. Framerates of up to 120FPS are available.

Many people like to record their videogame playing so they can share the recordings with friends or even to publish them on videoblogs or specialized sites.

This program lets you record your video game activity in a very easy way. Once you have downloaded and installed the program, you only need to open it, start playing a videogame, and click on CTRL+F12 keys to start recording. Is that easy.

The program has two modes. In the first one, the program's logo will appear onscreen on top of the videogame. As I've said, you only need to click on CTRL+F12, and the recording process will start. To stop it, you only need to click on CTRL+F12 again, and the program will save the recording automatically.

The second mode is Full screen, which means that the program will record all that happens on your screen, even if it is not a videogame. I used this function to record a video from a very, very old MS DOS game, and it worked beautifully. The process to start and stop the recording is the same as with the first mode.

The main disadvantage is that the free version shows a watermark on the video you recorded. If you want to get rid of this, you will need to upgrade your program by purchasing a subscription.
