Just read through this thread and did not see any references to the problem I have been having since I upgraded to 10.5.3 from 10.4.11. In many sectors I experience
"horizontal blanking," that is to say, portions of the screen go blank in horizontal bands. It is "flickering" (in a way) but not the entire screen; a horizontal band will blank for a portion of a second, then a lower portion of the screen will do the same, and in a few seconds, another portion of the screen will do the same. There is no noticeable pattern to the "blanking", either in screen position or timing. Anyone experience the same or similar problem?

Any ideas??

I think your computer is too fast.

Seriously, though, That's a new one. Sounds like some video driver bug to me.

Might be worth trying to turn on vsync.

the video card is the bottleneck O_o.

They usually are, with macs.

Holy sweet mother of god RattMann.

I read ray's post...then I read your specs....

god.

why the crappy video card?!

Probably the low-end option. You can get up to the NVIDIA Quadro FX 5600 with 1.5 Gb or on-board RAM with the Mac Pro.

For a pretty penny, yes...

OS: OS X Leopard (10.5)
CPU: 1.83GHz Intel Core Dual
RAM: 1 Gb
Video Card: GMA 950, 64Mb

... VO works like a charm for me.

Mac Mini? VO doesn't seem like a resource-hog, at least on the Mac.

Rattman.. your computer sucks, you should go buy a new one..

and, I'll even do you the favor of taking that old one off your hands so I can have an awesome machine like th.. errrr so I, uhh, have something to play pong on.. yea..
