When emulated ray tracing was available, a very significant amount of the crashes related to ray tracing we got through our Crash Reporter tool were happening in the 10x series cards. These crashes where happening mostly on the driver side or in TDR timeouts that were not actionable in our side. That means a lot of engineering and QA time spent on a path that is not future looking, so we decided to disable it leaving the code for users who might want to enable it at they own risk. Enabling that again will mean that time we need to invest in improving this technology will be spent on fixing and workarounding things on a code path that is not future looking.
Nvidia just updated the info of their RTX plugin specifying that a DXR capable GPU is needed for using that plugin, DXR emulation is not officially supported there anymore.
