This is definitely the approach that film studios use to make fashionable particular results look so good. But these movie studios have render farms of dozens of computer systems working for hours and even days to ray hint every particular person body in a particular results shot. A sport wants to have the ability to crank out at the very least 30 frames per second in your one lowly laptop. There simply hasn’t been sufficient computational energy within the common laptop to run ray-traced graphics.
But here is the place there’s some attention-grabbing information. At GDC 2018, Microsoft and NVIDIA demoed new know-how that helps ray-tracing in video games. Microsoft’s tech, referred to as DXR, provides software program help for ray tracing to DirectX 12, the toolset that underpins most Windows video games. NVIDIA introduced help for DXR in addition to hardware-acceleration for real-time raytracing for its Volta line of graphics playing cards. AMD additionally introduced driver help for DXR, and a few updates to its personal ray tracing applied sciences referred to as ProRender.
NVIDIA’s RTX is probably actually thrilling. Hardware acceleration is a component of what makes issues like enjoying again HD video so easy on most fashionable computer systems, and it is in all probability essential to real-time ray tracing. NVIDIA, Microsoft, Epic Games, Remedy and some different studios have proven off unbelievable demos of ultra-high high quality sport footage utilizing ray tracing and being rendered in real-time.
It’s an enormous technical achievement to get footage like this rendering in actual time, however there are a number of the explanation why it could nonetheless be some time earlier than you see ray tracing in your favourite video games.
