Mishnah Berurah 94:11 writes in the name of the Levush that during prayer one should face the precise location of Jerusalem; thus one would only face directly east if his location was at the same latitude as Jerusalem (although see the end of this answer, where even that may not be true). For most the United States and Europe, one should face southeast.
