Assetto Corsa Competizione was supposed to get support for NVIDIA's real-time ray tracing technology but it seems Italian game studio Kunos Simulazioni has changed its mind. While responding to a question from a user, the developer replied that there's no plan to support RTX in the foreseeable future.
The developer did not rule it out entirely, but stated that RTX support is very low in the list of priorities:
"Our priority is to improve, optimize, and evolve all aspects of ACC. If after our long list of priorities the level of optimization of the title, and the maturity of the technology, permits a full blown implementation of RTX, we will gladly explore the possibility, but as of now there is no reason to steal development resources and time for a very low frame rate implementation," said the developer, in response to a question about NVIDIA RTX support at launch. This is significant, as Assetto Corsa Competizione was one of the posterboys of RTX, and featured in the very first list by NVIDIA, of RTX-ready games under development.
