I have never seen e17 > produce this kind of choppy desktop. e17 just thrw a few dumb large textures (big triangle pairs to make rects). e18 + throws much more geometry at gl. all the text in e (titlebars, menus, shelf) is renderd as text. it uses less memory and is actually far more flexible and powerful, and it works fine if you aren't re-rendering the bits you don't need to. i have an intel laptop, intel desktop, nvidia desktop, only accel-less laptop, another intel laptop, another nvidia laptop (nouveau)... i know of other drivers. i have far more than just one machine. if you don't have extensions to partial-render, then it full renders. full rendering is far more in e19 vs e17. that's not going to change any time soon. more complex gadgets will cost more. text with soft drop shadows or glows will cost a lot more. they don't get held in memory as a texture/pixmap - they get generated on the fly. -- ------------- Codito, ergo sum - "I code, therefore I am" -------------- The Rasterman (Carsten Haitzler) [email protected] ------------------------------------------------------------------------------ Want fast and easy access to all the code in your enterprise?
