</div>You're using virtualgl instead of primus. If you want to compare<br>
Debian (where only primus is packaged, not virtualgl) and Arch with an<br>
environment as similar as possible, install primus and try<br>
$ optirun -vv -b primus glxgears<br>
<br>
(Note to self: I should definitely get around to packaging virtualgl...)<br>
