Hi Matthew, There are a couple options that can be tweaked within CAVE to dedicate more resources which can help with performance issues, but unfortunately I think the 4GB of RAM on your machine may be the limiting factor. To get CAVE to run very smoothly, I think something more along the lines of 8-16GB might be necessary. Sometimes, this can also be dependent on the graphics card and how much memory it has available as well. I will say that we only support NVIDIA graphics cards to run CAVE. There is a setting in the "CAVE" menu > "Preferences" > "Performance". There you can try and increase the viz cache, but ultimately this will be limited by your hardware. I hope this was helpful, sorry I didn't have better news for you. Thanks. --Shay Carter Software Engineer II UCAR - Unidata Ticket Details =================== Ticket ID: DUJ-204625 Department: Support AWIPS Priority: Normal Status: Open =================== NOTE: All email exchanges with Unidata User Support are recorded in the Unidata inquiry tracking system and then made publicly available through the web.
