Mention the words ‘Unreal’ and ‘Engine’ to a PC gaming enthusiast, and they will no doubt immediately think of incredible-looking graphics, as demonstrated in the likes of Black Myth: Wukong, Senua’s Saga: Hellblade II, and A Plague Tale: Requiem. However, there’s probably one other thing that PC gamers associate with Unreal Engine and it is stutter. If you wondering just what that is and why it happens, the maker of UE has explained it all in a new blog and detailed just what it’s doing to prevent it.

Let’s start at the beginning. Shaders are small pieces of code that are used in graphics rendering to do a very specific task. It might be just to move a triangle about a screen or it could be for something such as calculating the colour of a pixel, based on multiple light sources, materials and other effects.
