Remedy Shows The Preliminary Cost of NVIDIA RTX Ray Tracing Effects in Performance
Real time ray tracing won't be cheap. NVIDIA GeForce RTX 20 Series graphics cards are quite expensive, but even with that resources the cost to take advantage of this rendering technique will be high. We didn't know for sure what this cost would be, but the developers at Remedy have shown some preliminary results on that front. This company is working on Control, one of the first games with RTX support, and although they have not provided framerate numbers, what we do know is that the activation of ray tracing imposes a clear impact.
It does at least in these preliminary tests with its Northlight Engine. In an experimental scene with a wet marble floor and a lot of detailed furniture they were able to evaluate the cost of enabling RTX. There is a 9.2 ms performance overhead per frame in total: 2.3 ms to compute shadows; 4.4 ms to compute reflexions; and 2.5 ms for the global denoising lighting. These are not good news for those who enjoy games at 1080p60.
