To summarize what I think I know from the other forum:
Does that just about sum it up?
Using ACR from PS3 or PS4, no problems. Using ACR 6.4.1. and making a batch convert, from nef to jpg ( or to other formats) I receive "not enough memory" sometimes, and all the times when I select reducing noise and lens corrections. It happen also when I try to transform only one nef to jpg.
I have win 7, i7, memory in triple channel, the system on a SSD, the scratch disk of win on another free SSD and the scratch disk for PS ans ACR on another SSD. I have tryed all imaginable settings, and no hope to use the ACR. Old ACR are OK, only this 6.4.1 have a big problem on my system.
