Forza Horizon 4 Not Allowing Game Capture With Any Streaming Software

Hi my name is Steven (ElusiveNerd) and I am a partnered streamer for mixer.com and as I have been playing a lot of forza I have began to stream it. The game will not allow game capture on any streaming software what so ever and I need to do so as its better
for the performance of the streaming software while gaming. Its only with forza that everyone I have seen on forums have this same problem. I have a i7 6700k processor and a gtx 1080 so I have no problems when it comes to my setup as I play a lot more demanding
games on my pc while streaming and have no problems. I hope this problem can be sorted as there is a lot of streamers out there that would like to see this fixed like myself.

:)
