Help with video...?

Hey fun people. Been BeatSabering for almost 3 weeks and still haven't finished my first map, but having got into the custom sabers and now avatars I'm going down the rabbit hole of vid capture so once I actually have customs to show I can show them off 😊HOWEVER.... I've hit a bit of a snag. I don't have a really high end machine (gtx 1060, amd fx-8320, 8gb RAM - runs BeatSaber fantastically with my Vive, mind) - ... but I'm having trouble getting decent quality video capture. The only success I've had is with the OBS settings really low and the captures are pretty poor quality with lots of artifacts - it seems most settings make BeatSaber crash if I have custom sabers or avatars on. Even without them I'm still trying to work out the best quality I can muster from my fairly underpowered system.Any tips from experienced ppl working with a lower end system on settings in OBS I should try to get half-way decent video?Thanks in advance!
