hello
i upgrade my mac pro 1.1 with a xfx hd 5770 PC card,that works very good after os x has booted
im running lion with latest updates. and i cant open any 3d app or opengl,its crashes
i installed steam and tried to launch half life 2,it show down its opening but the icon goes away after 2 seconds. also i tried other games but same result its icon show for a couple of seconds then it goes away.
in windows games play perfect.
i downloaded gputest,but when i hit run benchmark i get "gputest quit unexpectedly"
using firefox on youtube with latest flash player installed, video works perfect
what could cause this problem ?

There is always a reason.
In this case your GPU.

Check whether this GPU is supported in Snow Leopard.

right out of the box.. no but after i install some updates,yes it works.
should i downgrade back ? or there is something i can do ?

Pretty sure this card will profit from an EFI flash (especially in older OS X versions), have a look over at netkas.org.
Some cards where buggy in Lion when used without injection, I guess yours is one of them.

i have bootscreen.. and also dvi ports work fine,lion detected the card as hd 5770 !
