I'm using Mistika VR v.8.8.4 on an iMac Retina 5k, 4 GHz i7, 48 GB RAM with an AMD Radeon M395 card. Getting render speeds of 2.9 fps when I output 4k files. I'm a new user, and I haven't been able to find any info on exactly what to expect. Is this slow, fast, or normal? Is there a way to speed it up? Can anyone point me to a simple, accurate tutorial or written instructions that specifically covers rendering? Thanks!
