Thank you John for this information.

I have a few questions regarding this important update:
1) Which NVIDIA GPU RTX models would you recommend to better (and fully) exploit the performance improvements offered by this update?
2) Dees this VMD update improve a little the TachyonLOPtiX ray tracing performance even if different NVIDIA GPUs are used (like Quadro P6000)? Or is it strictly specific for RTX models?
3) Which kind of benefits should I expect when dealing with 100 million atoms systems in terms of loading a state, interacting real time with the system, changing representations, visualizing a trajectory and rendering images/movie?

Thank you

 Now that the NVIDIA drivers with RTX support are generally
available, I have made a current 64-bit Linux test build of VMD 1.9.4 (a29)
that includes RTX hardware-accelerated ray tracing, and it is
posted on the web site. To use this version you will need the latest
NVIDIA 418.xx (where xx >= 30) driver version from the NVIDIA web site.

VMD users should expect TachyonLOPtiX ray tracing performance gains
that range as high as 8x faster when comparing the new RTX GPUs with
the new VMD with prior versions of VMD running on so-called
Pascal and Volta class NVIDIA GPUs.
