If I set my game fixed to 120FPS, on my Alienware PC which is Intel i7 quad-core CPU, 8-threads, I get a blazing fast experience. It hits 120FPS easily on discrete GPU or integrated GPU. When I run the same game on both my dual-core PCs, one with Intel CPU 4 threads (Surface Pro 4) and the other with AMD CPU 2 threads (HP all-in-one), they both struggle and fluctuate between 20-50FPS! Nowhere near 120FPS!
Does a basic UE4 application, require a fast PC to run it? The thing is, in my debugs, the Tick() function on all the objects, gets the correct delta time of 8ms, which is 120FPS?
