Playing with my new V10, I came across a few new things in xsetmon (coming from MGRAS SSE):

1- a shitload of new resolutions, that's cool! An interesting one is 1280_1024_safe, what's this for? safe as in secure or stable? I don't recall seeing that on SSE, but maybe I just didn't pay attention...

2- a new, slightly puzzling "Valid Configurations" menu
This one got me puzzled because for a certain number of resolutions, it offer 2 options. For instance, 1280x1024_60_no_tiles.cmb and 1280x1024_60_4_tiles.cmb. What the heck is this? I'm guessing it's the OGL Multipipe thing, hence the 4 tiles... Am I way off on that one?

3- a new frame buffer depth control, I guess it's related to #2

noticed that one too. The two seem to be exactly the same vfos though.. no idea if its just an accidentally packaged backup copy or if its there for a reason..

Those are display combinations for using several odyssey pipes with an external compositor (InfinitePerformance(TM) ;-) )if i'm not totally mistaking.. see sgcombine(1) for example

this is used to switch between 8bytes/pixel and 16bytes/pixel framebuffer depth, see http://forums.nekochan.net/viewtopic.php?t=2758 and friends :-)

OK, so that's pretty much the opposite of what I thought... It's combining multiple VPro instead...

That's directly related to the normal display? what an odd location in the UI for this choice...
