Just noticed that on my new computer ( Athlon Opteron 170 Dual Core with GF6600 PCI-E video card) the latest drivers (81.95) from Nvidia are causing a bit of a problem. Seems the latest drivers don't play well with AC9. I believe these latest drivers are suppose to enhance or work better with the newer dual core cpus.
Problem I'm having is that the cpu usage will hover around 65% or more. And this at total idle. Weird.
Any Graphisoft guys notice this yet?
I did install an earlier driver 78.05 and it cleared up the problem.
