Lots of ideas. Can you run demanding native apps such as Google Earth? It
took me a couple driver updates from ATI before GE worked properly. Not
surprisingly, the improvements carried over to X. We have Hummingbird
Exceed at work, and find that new machines often need updates of graphihcs
drivers and or Exceed to work properly, so 1) check your app and drivers
for updates/bug fixes, 2) try Xming (free) -- works for me and even
supports SGI's gr_osview, 3) run a recent linux in a VMware appliance on
your desktop, 4) try a different video card (some models just never work
properly on demanding apps although they are fine when running MS Office),
and 5) watch out for overheating and power supply problems if you have a
recent high-end graphics card.
It seems to take 6 months to a year before all the bugs are worked out for
a new graphics card/drivers, so for reliability you want to shop for old
stock from name-brand companies being sold at a discount rather than one
based on last week's chipset.
