FFmpeg, how to record game over than 30 fps? Im trying to record Windows Desktop, a game (Worms Armageddon) which has about 50 frames per second. If I check it closely, I can see some frames are missed. The command:

ffmpeg -probesize 10M -rtbufsize 1500M -f dshow -i audio="virtual-audio-capturer" -acodec pcm_s16le -f gdigrab -framerate 60 -i desktop -vcodec libx264 -qp 0 -threads 0 -crf 0 -preset ultrafast -tune zerolatency output.mkv


what else can I do?
This might be an issue with the hardware unable to keep up with the required process of recording (compression) and writing to disk, which will result in dropped frames. That being said, your flag for crf should increase by a ton, and remove the qp flag. Set the crf to 17-25 to ease off the required processing power.
