Hi Jarrett, Thanks for the quick reply. I am using version 3.03 on Linux and Mac. No conda package is yet available, so these are the Schrödinger provided binaries. Ray Tracing definitely uses only a single CPU.
Regarding the Draw problem, I have the example that I used in my coursework. Can you point me to a place where I can upload it to? I have the Pymol session and the Draw/Ray videos. The total size is ~440 MB. BTW, I thought that saving a session with an active Timeline would save the Timeline as well, but that doesn't seem to be the case as you can see when you open the session file. Many thanks, Istvan On Fri, Jul 19, 2024 at 6:19 PM Jarrett Johnson < jarrett.john...@schrodinger.com> wrote: > Hi Istvan, > > With regards to CPU ray tracing only running on a single core, that sounds > like a major regression; we haven't changed anything in regards to that so > I'll investigate.
