PS - Did you say you were getting a bit of ball stutter in Windows 7 x64? If so, Can you try something for me? Turn on an Aero Theme (default windows one will do) but leave the backdrop , don't change it to solid black or anything and let me know if it makes any difference for you - I ran Windows 7 with ball stutter and making this change made it run smoothly for me....
Sorry for the slightly OT spinning on here, but this sounds interesting...
Love to hear if this have any global effect on stutter for tables in general when on W7

Hope to hear how it works out for you...
Cheers!
I orignally started mucking around with my settings because I was trying to get Monopoly to work without stutter.
Here's what I did:
Using the latest NVIDIA non-Beta drivers at the time (I think 275.33) I went into the NVIDIA control panel and selected Manage 3D settings and set everything as follows:
Multi-display/mixed-GPU acceleration - Compatibility Mode
Power Management mode - Prefer Maximum Performance
Threaded Optimisation - Off
Vertical Sync - Off
Tried again (running Monopoly at whatever defaults it was on, Flashers running etc and it still stuttered.
The final thing I did was go into Control Panel, go into Themes and select the Windows 7 Aero Theme (then set the backdrops to Black Solid colour again).
Tried Monopoly again and it's now running smooth as silk. (Brilliant game by the way and looks beautiful).
Later on I found another bug with Windows 7 - if you use a Black Solid colour and Aero it causes focus issues with Hyperpin at startup, so I ended up creating a black jpg and set that as the background.
Be curious to know if this works for anyone else..
Thanks,
Mick
