NVIDIA Turing architecture RTX 20 series graphics card's biggest highlight and selling point is to support real-time game ray tracing, there are already more than 10 games ready to support, but there is no official release, currently only experience some DEMO, try or simply run Minute.
Real-time ray tracing is believed to be widely known for the huge consumption of computing resources. This is the root cause of the game that has been used for many years but has not been used for many years. Although the RTX 20 series has been implemented, a large number of dedicated units have been added for this purpose. The cost is still heavy.
Remedy's "Control" is one of the first games to support RTX 20 ray tracing. The game engine is Northlight. Now, Remedy has released some data, let us have the first impact on ray tracing in real games. A preliminary understanding.
Tests show that if ray tracing is turned on in a typical scene with 1080p resolution, the RTX 2080 Ti will consume 9.2 milliseconds per frame, including calculating shadows for 2.3 milliseconds, calculating global noise reduction for 2.5 milliseconds, and calculating reflections for 4.4 milliseconds. (the most time consuming).
We know that if you want to run out of 60FPS's smooth frame rate, the rendering time per frame can't exceed 16.7 milliseconds, plus 9.2 milliseconds consumed by ray tracing, then the actual frame rate is only about 39FPS!
This is still the performance of the top RTX 2080 Ti at a low 1080p resolution, think about the RTX 2070, think about 4K...
Although these are still preliminary data, NVIDIA and game developers will further optimize, but it is clear that the road of ray tracing is still very long...
