However, Jitter all inclusive allows for much more flexibility in what/how etc gets drawn (esp. with 1.5 with full shader support, etc). I know shader support is in cvs, but ive yet to toy with it for GEM.</SPAN></DIV><DIV><BR class="khtml-block-placeholder"></DIV><DIV>I might be persuaded to do a bake off on a group of patches.
