real world mapping and 1.09.03r

Could anybody confirm if the new real world scale mapping features of max 7.5 are compatible with version 1.09.03r?

After further testing, it seems my version of Vray is *ok* with real world texture sizes, but I seem to have a limit of 1m x 1m for my textures - any bigger than 1x1 and the textures don’t get any bigger! Anyone else share this issue?
