Unless things have changed massively in the last 3-4 years, you almost |
25 |
certainly were using xv without really knowing about it. With just 'x11', |
26 |
you're forced into using software scaling instead of hardware scaling, which |
27 |
massively slows things down. And hardware scaling has been a feature of |
28 |
essentially every video card since, I dunno, 1994 or earlier? And the xv |
29 |
extension has been available since 1991... |
