There's alot more to optimizing a PC for recording than just the swap file and vcache settings. As CyanJaguar eludes to, other things usually need to be done for the PC to be stable and happy.
I would ask CyanJaguar a question however. Tell these fine folks how to disable the static vxd's as most people don't know how. As for the rest, almost everyone will tell you:
Activate Busmaster operation
Limit Hard disk Cache (vcache) to 16384 min/max Or use the formula shown above by oneArtist.
Disable CD-ROM notification
Disable System sounds
Best Color Depth is 16 bit (High Color)
De-activate Screen Saver
De-activate Power management
Don't use 'animated windows'
Exit Task scheduler
De-activate scrolling Tooltips
Disable scrolling Taskbar
Use msconfig to disable startup items
Set your swapfile size manualy
etc...
There are more things, I repeated some that CyanJaguar stated because they are all important to do!
All of these things are found on the web for anyone who looks for them. But knowing what to use is the bigger question that I hear most often.
Now it just so happens that I am trying to put together a real time chat soon for users of another forum. The chat will cover PC optimization on a per PC basis so if you've tried tweaks and they did not work, we can talk about your specific setup. As I am new here I don't wish to solicit anyone or be spammed, but with the amount of optimization questions floating about I just have to ask if anyone is interested in participating. If so, please let me know by email rather than taking up post space here. Or visit
Collaboration Central for a followup.
I do this only to help and for no other reason than the love of figuring out a puzzle.
