RealityServer with support for NVIDIA RTX technology is here! This release includes a major Iray version bump which adds support for accelerating Iray rendering with the new RT Core hardware inside RTX cards and the Tesla T4. There is also a great performance improvement for Iray Interactive (on all cards) and support for MDL 1.5. Let’s take a look. <\/p>\n\n\n\n\n\n\n\n

Iray RTX 2019.1<\/h2>\n\n\n\n

The main change in RealityServer 5.3 is the update to Iray RTX 2019.1. This brings optimised support for Turing based cards, both those with and without the RT Core ray-tracing hardare. If you have a card with RT Cores such as the Quadro RTX 8000\/6000\/5000\/4000, GeForce RTX 2080 Ti\/2080\/2070\/2060, TITAN RTX or the Tesla T4 you’ll see a performance improvement from this new hardware.<\/p>\n\n\n\n

So what kind of performance gain can you expect to see? Well it is very scene dependent, we’ve seen an average range of 5% – 300%. Since that is pretty wide we’ve written a separate article explaining the ins and outs of NVIDIA RTX performance with Iray.<\/p>\n\n\n\n

RTX Performance Explained<\/a><\/p>\n\n\n\n

In addition to the new support for RTX hardware we see a smaller general performance boost on all hardware for Iray Photoreal. Iray Interactive sees on average 2x speed up<\/strong> for interactive use cases and that’s on all hardware not just RTX. So this is definitely a worthwhile update for those using Iray Interactive mode, no matter what card you have.<\/p>\n\n\n\n

Of course Iray continues to work as usual on older hardware as well, however Kepler based cards are being deprecated in this release. They will still work for now but support for them will likely be removed in a future Iray update. To get access to the RTX features you need to be running driver version 430.86 or later on Windows and 430.26 or later on Linux.<\/p>\n\n\n\n

Oh and there is also a significant speed-up for CPU based ray-tracing by using the Intel Embree library, up to 2x in some cases and if using CPU only mode startup time has been reduced. Seriously though, are any of you still using CPU rendering?<\/p>\n\n\n\n

MDL 1.5<\/h3>\n\n\n\n

With the updated Iray comes support for the latest version of MDL, the Material Definition Language. Here are the main two features of MDL 1.5 that will affect RealityServer users.<\/p>\n\n\n\n
