Unreal is probably eating up gpu. If you don’t limit your fps in your game then unreal will use all your gpu utilization to get as many frames as possible, which would cause your game to run very choppy and slowly.
You should add a ‘‘Event BeginPlay’’ node and attach a ‘‘Execute Console Command’’ on your level blueprint or on any blueprint in your level. In the command text box, enter ''t.maxfps 60" (The ‘‘60’’ is the limit of frames, you can change it to be whatever you’d like.)
This should work, since it has happen to me and this was my solution. Hope it helps.
