..has been released by now, here a nice write-up by migenius on
expected performance increases when using NVIDIAs RT Cores (benchmarked
on the slightly older 2019.1.0 version): https://www.migenius.com/articles/rtx-performance-explained
The
good news in a nutshell: Both iray interactive and iray photoreal are
much much faster now for geometry heavy scenes, and using instancing
(i.e. to be able to use much larger and more detailed scenes) is way
cheaper in addition.
On top of the good news we optimized some parts of iray interactive to render faster on all GPUs, so one can expect a 2x speedup for most scenes even on non-RTX cards.
Things do not stop there though, as iray photoreal also got a free ~2x speedup when using the CPU for rendering.
Daz3D also already included the 2019.1 builds into their latest BETAs, see https://www.daz3d.com/forums/discussion/341006/daz-studio-pro-beta-version-4-12-0-42-updated
