Guild Wars 2

So I recently got overwolf in order to do some in game recording. However im having some issues with it.

The recording itself after the fact is extremely choppy. Even though I had no choppiness whatsoever while playing.

Whats interesting is that even though its choppy. The cursor movements are perfectly smooth. As if its separate from the rest of the recording. Also the audio seems to be perfectly fine as well

My computer as a little outdated. But is still well enough to run gw2 at medium quality at 50-60 fps in most places and 30 fps in zerg fights when im not recording.

The recording was at around 30 fps at 420p.

The recording is posted here if anyone wants visual info : https://www.youtube.com/watch?v=g2qTLKooSc8&feature=youtu.be

Edit: haha just realized I forgot to actually ask.

If anyone has any suggestions on how to fix this issue. Please tell me. I really want to make some shout ranger gameplay videos. But as it is now there more of a pain to watch than there worth. I would really appreciate any advice.
