I have tried a number of different settings to try and record my fortnite game in good quality but whenever i go to watch it it's always laggy. I have an i7-8700 CPU @3.20GHz, 16GB RAM and a GTX 1080 card. I'm using the (NVENC) new setting with CBR rate control at 25000 bitrate, keyframe interval is 2, preset and profile is Max quality and high, look ahead and psycho both ticked with Max B-frames as 2. Also my Base canvas res is 1920x1080, Scaled res 1920x1080, Lanczos, common fps, value 60fps.
