HI everyone
and sorry if I post a question already answeared. Also sorry for my bad english (I'm italian).
With new 3.0.0. release of Virtualbox the video acceleration is now enable, but I'm a software (Microsoft Train Simulator) that when I launch don't work, and it return this error message:
"Train Simulator require hardware acceleration"
I correctly checked the "Hardware acceleration enable" in Virtual Machine Option, and also I correctly installed (in safe mode) the Guest Addition.
Is there any solution?
My system is:
Host PC: HP Intel Core 2 4300 @ 1.80 GHz Windows Vista Home Premium SP1 - NVidia GeForce 7500 LE
Guest OS: Windows XP SP1
Thanks for all the answears.

Is Direct 3D in "dxdiag" enabled. If not, install Guest Additions in windows safe mode (F8 at boot).

If that doesnt help, then forget it. 3D in VM is very crappy.

Thanks Stefan, but as you suggest "I'll forget" because don't work. Thanks anyway
