High CPU usage

I am running XP Professional. It is a clean install with about 30 processes after startup. Muting sound reduces CPU usage by about 5%, although turning off the Parallels tools doesn't do much.

Also, might just be the way Windows handles the command key, but when I press Command+Tab to switch between Windows, Parallels ends up expanding my Start menu in addition to OSX switching my active application.

It is bug - thank you for reporting. We will address it in upcoming update.
 
After trying out the beta all day, I have to say that the graphical performance is subpar compared to that in the last released build. Right clicking takes a long time to bring up a context menu, for example. Window redraws are also pretty slow.

I hope these problems are fixed in the GA. Overall, I am pretty impressed :D

agranovsky,

You can significantly reduce CPU usage by 3 things:

1. Disconnect all USB devices from virtual machine (menu Devices->USB).
2. Mute Sound (menu Devices->Sound).
3. Close Parallels Tools Center in guest Windows (right click on icon in tray and menu Exit).

We are investigating all these CPU usage related issues and will come with fixes soon.

Andrew,

None of these made a major impact (I did have USB disabled previously), but thank you for trying. I hope you get it right soon; it still would be nice if you could give us a hand with downgrading to 2.5 (I have an outstanding support ticket related to that, but so far -- crickets).

Thanks,
Alex

I love how you address the command bug, which has been experienced.. but not the high-cpu and ram usage bug.

I repeat - I can come down to Renton and let you run anything you want on my Mac w/ Vista (although I assume you have computers of your own with these setups) to try and figure out what is causing this problem.
 
I uninstalled the beta and went back to 4560. The graphical performance in the beta was terrible, and I couldn't figure out a way to disable the shadows without going in full screen mode.

Hope the GA is better.

When I close ("Exit") Parallels Tools Center (PD 2.5.3124, XP Pro SP2), I get the message, "Shutting down the Parallels Tools Center will stop the Clipboard Synchronization and the Time Synchronization. . . ."

What do these synchronizations actually do? Is it advisable to turn them off?

Clipboard sync lets you copy and paste between the guest and host OS. Time sync keeps both the guest and host operating system times the same.

That is what I thought. Doesn't sound as if they should be disabled, so I wonder why Andrew suggested it?
