"Speaking of performance, Hogwarts Legacy is a very CPU intensive game, especially with ray tracing enabled, as the CPU usage is mostly single-threaded on PC due to a very poor implementation of Unreal Engine 4 DirectX 12, and high-powered GPUs such as the GeForce RTX 4080 can end up CPU bottlenecked in some sequences of the game, even at 4K. We've seen these issues before in other recent Unreal Engine 4 games, like The Callisto Protocol or Gotham Knights. In such a CPU limited scenario, a very welcome help comes from the DLSS Frame Generation technology, which has the ability to bypass CPU limitations and increase the framerate. With DLSS Super Resolution in Quality mode and DLSS Frame Generation enabled, you can expect more than doubled performance at 4K and 1440p, and during our testing, overall gameplay felt very smooth and responsive, we haven't spotted any issues with the input latency."
This is why I hate the likes of DLSS, it's being used as an excuse to not optimize games. We all saw this coming.
