dynamic ram preview limitation size

Hello:
It is normal to have only 1Gb allowed fort he dynamic ram preview in Vegas pro, or is just my case?
I use to have more in older versions, having less RAM than I have at the moment:
4 Gb, ( but winxp recognize only 3.5)

I think that they limited the RAM preview size to a more sane number in VP8 so that people would have fewer problems caused by allocating too much ram to preview caching.

AFAIK, the setting is actually just calculated by the input field in prefs. You could probably set it manually in the internal settings tab of the prefs (Hold shift while you open prefs and you'll see that extra tab).

Applications get 2GB of virtual address space in 32-bit XP and Vista. This is a combination of physical RAM and Page file space. Setting your Preview RAM setting very high pretty much ensures that something has to be moved to the page file and this can slow down Vegas.

Click Options, then hold the shift key down while you click Preferences.
