I'm trying to setup an openEXR workflow, but I just get 20 fps out of DaVinci... I tried all types of compression with no luck.
I'm using an 8 core mac with an Caldigit RAID (600MB/s), 3 Quadro 4000 and an GT120.
Unlike DPX, EXR files are not designed for efficient disk I/O. There were designed for VFX images where disk speed of a few frames per second was considerably faster than the VFX render speeds. We continue to find ways around the file format limitations to improve I/O for EXR but in the meantime, depending on your workflow, consider the 16 bit floating point dpx files Resolve reads and writes.
