Hi Chimera users, I've been working with what are probably some pretty big files (400 MB - 3 GB) for ultramicrotomed sections of holograms. I've trimmed the volume down as well as I can while keeping it large enough to see what we ultimately were aiming for. However, I am running into some hardware resource issues. None of our computers in the lab can handle it, so I've been using my gaming rig at home to do it. I run a server off it also, so have some decent hardware to work with, but I cannot figure out how to reallocate the resources that Chimera seems to default to. I have 64 GB of system RAM available, and after recording 1-2 movies of rotations or a flythrough of clippings etc. Chimera has never used more than 1.5 GB. My graphics card has 4 GB. After filtering and post-processing, before any rotation or video capturing, the vid card has used around 2 GB already. During video capture, depending on if I'm rotating or clipping (clipping uses up a lot more faster), the vid card memory slowly gets eaten up, eventually crashing Chimera altogether. I can usually only get about 800-1000 frames before this happens on a smaller file (400 MB), and usually can't get through a whole 10s, or 250 framed, video on one of the larger files. I have pretty limited experience with this program, so I'm hoping it's a simple settings or otherwise fix I've overlooked. Any suggestions on this?
