psh. i'll be impressed when i see it run a program that syncs itself to vblank, running in a window without it either having to drop or buffer frames from said program. seriously, fuck this culture of excessive buffering of frames! IT"S NOT OK! as john carmack recently pointed out, it's faster to send a packet across the globe than it is to get a pushed frame displayed on your monitor nowadays. (yes i know it's primarily a fault with displays, but software should do whatever it can to not add to the problem)
Every time I see tear-free I read it as tears as in crying.
So, now you can watch video on Linux without bursting into tears.
