You appear not to be familiar with exactly what "2D acceleration" is, how generic it is, and how little it has to do with the actual application level number crunching. 2D acceleration has been around since the days of PCI graphics with 256KB frame buffers, and yes, even in Linux (or more correctly, XFree86 and today Xorg). If you own a card made in the last 10 years with enough frame buffer space to hold your entire resolution at the correct colour depth [*], upgrading to a new card will do absolutely nothing for your application speed when dealing with programs such as F-Spot, GIMP, etc. The recommendation was to upgrade from a low-end ATi video card to something better to improve F-Spot performance. This is incorrect, and will not yield the performance benefits desired. The bottleneck is somewhere else. My guess is F-Spot is doing some heavy reading or pre-caching of images from the disk on first start, which is usually the case for such programs. A lot of this can be disabled in the application preferences. - -Dan [*] Some maths for you: "Full HD" is 1920x1080 at 32 bits per pixel. 1920 pixels * 1080 pixels * 4 bytes per pixel / (1024^2 bytes per megabyte) = 7.9MB It requires only 7.9 MB of framebuffer space to store a screen worth of information at HD resolution with full colour depth. Anything more is totally unused when dealing with programs like F-Spot and other image viewers. -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.6 (GNU/Linux) iD8DBQFIcS3ZeFJDv0P9Qb8RAkHsAKCm4FI8QEoLmZzMInXi/hBC6o7RyQCdH1I6 qyAnaaWSp7J2ep56OOrA/i0= =tm5o -----END PGP SIGNATURE----- -- ubuntu-au mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-au
