hiya mate, what 10th gen i3 is it? because the gt 1030 is a subpar gpu, you’ll more than likely have to upgrade in some time, now for fortnite, you’ll have to run it on performance mode with low mesh’s and low view distance, for streaming i’d recommend using x264 with 5000kb/s bitrate, your fps should be okay with them settings as your using your i3 for encoding not the gt 1030
