Glass Windows

[gadzooks]

How do you guys and girls handel glass windows in a architectual interior renderings? It seems that if i turn on my glass and try to illuminate the space the rendering times go waaaaaaay high. Is this common in vray?
are thier work arounds? Thanks

U Can Calculate the IR map with the GLASS off/hidden. and then using the saved IR map turn the GLASS on. works most of the time.

( That is if u don't need things to be very accurate and caustics for example )
