I'm trying to use this work around to get cuda working when using aerender from the command line. It says to edit the Debug Database.txt, but I have searched my whole computer and it doesn't exist. So I guess I can create one in the right place, but I'm currently on windows and have no idea where to put it.
I know it should go in the preferences folder but where is that in windows 7?
I strongly recommend against trying to do this. It is untested and unsupported. The article that you linked to is by someone who has tried this on a Mac, so there aren't even examples out there of someone doing this on Windows.
No Adobe employee is going to help you to use this untested and unsupported hack using a debug database flag that was added for internal development purposes.
ok, but if it does work it saves me A LOT of render time. What's the worst that can happen? It crashes and I switch it back to default. Or is there risk to the graphics card?
