I’ve installed 11.3 RC2 (64 bit) with no problem. Great install - just a few things i needed to tweak/install (display/wireless drivers). Installed latest 64bit linux driver from Nvidia for my card – a 260m Geforce… I’ve installed VLC to play media files, and all video play is fine for most formats, but when I’m playing mkv files, it is a bit stunted and choppy. I didn’t have this problem on my Ubuntu install with the same comp. It definetlly is not a lack of horsepower… running a quad 2.53 with 8 GB DDR3 mem, I’ve got dual 260M video cards that have a GB each - i haven’t tried to configure SLC though, so only one card is pushing out to the display but it should be fine.
it’s a quad – cpu use is low… the movies are hd… one is 720 and the other is 1080 – it occurs with either one. I installed mplayer, and no issues with that. tried upgrading vlc, but problem persists… i’ll just use mplayer for mkv files.
