VirtIO does seem to improve performance of an openGL video game ("enemy territory" used in the paper). However glxgears gets better performance (more FPS) using rtl8139. Perhaps a bandwidth v. latency difference? http://warburg.cs.ualberta.ca/~cam/dokuwiki/doku.php?id=vmgl Cam ------------------------------------------------------------------------- This SF.net email is sponsored by: Microsoft Defy all challenges.
