hi the game cashes at start of act 2 with the following message
error in application version 29980.2562
vertex buffer lock returned null pointer. out of memory

rederer: threaded
physic : threaded

can any one help

problably you have insufficient memory, like the bug report said. Post your system specifications maybe I can see what's wrong.

this is my spec
XP home editon
AMD Athlon 64X2 dual core 4200+ mmx 3Dnow
memory 1022MB ram
nvidia geforce 7600 256 MB 128 bit

either make sure all memory possible is free for GRAW, or install a second gig ddr, that will fix it.

I have the same problem !!!!!
my pc
p5k
e6600 3ghz
2gs ddr2 ocz 800
nvidia xfx 7600gt xxx ed.

can't even start mission one
same crash error

Q6600
7900GTX 512mb
2GB ram
XP pro

GRAW2 with latest patch

I have the same problem as importpsycho!
The game crashes when I try to start the first campaign. I can just see the chopper for about 3 seconds, than the screen becomes blank and I see weird 3D stripes. After a few seconds my computer restarts....

my PC:
7900GTX 512 MB
2GB ram
XP professional
Dual core pentium

DXdiagnosis and the GRAW minimum system requirements program did not find any errors

My machine was doing this using the latest Nvidia Drivers. Installing the beta drivers 1.63 fixed the issue on this machine.

YES, I solved it.

I adjusted the graphics settings: dynamic lighting was set to low, and it solved the problems. Hope it works for the others too.

Regards,
Michael

I have the same problem, "vertex buffer lock returned null pointer. out of memory" but I am using vista...
1-I have installed the games patches that didn't help.
2- I can't find the "frames..." option in my nvidia panel even when I installed coolbits I can't find those options...how do I get to these extra options....
Also, if anyone has a fix for this using Vista 3GB, nvidia 8600m GT
Please let me know

there is a tweak thread in the graw-PC forum, read thrugh that, it clearly states how to do it.
Good luck
