**wolf359**: I have Maxwell 1.7 so why would I want to downgrade to AR3? My comparison is with AR2 which I use with Cinema 9.6. Since using Maxwell I haven't had to upgrade Cinema either - another substantial saving (of cash). So in my case Maxwell has turned out to be economical :-)

A while back, out of curiosity, I tried rendering my (still unfinished) Eagle model with Cinemas' AR2 engine - it failed.  Maxwell done the job.
