So what do you think is the ideal software to record your PC screen when you try your C3 game to showcase it to the public?
I tried Filmora but the recording is snappy and not as smooth as I wish it was.
OBS Studio. Open source , very snappy and good to use
Develop games in your browser. Powerful, performant & highly capable.
Construct has built-in features that can do this - see the Video Recorder plugin.
