In the past when I did the recreation of Disneyland Fantasmic I used fraps because it produced the finished product quickly as i was using water jets in-game, the in-game recorder i knew about but did not realise how slow it was and that is was video without sound on export so i used fraps, since then i use the recorder i still have fraps as well as obs and my desktop has shadow play via geforce experience but can be tested with. As I am not sure how well they will work with the particle fireworks, lasers, and the fountains.
When I am in a new sandbox park the in-game recorder works fine, its just in the shows park file where it has problems because of the amount of custom scenery darknight is using for his recreation of Universal Studios Florida
