How to enable texture acceleration in a VM running XP?

In my Windows 8 PC, I'm running a VM with Windows XP vía VirtualBox. I'm trying to play a game that uses DirectX 8.1. The dxdiag tool says DirectX 9.0c is installed, so there's no problem with the version. Under the Display/Screen tab, I have:

• DirectDraw acceleration (enabled)
• Direct3D acceleration (enabled)
• Texture acceleration (not available)

I used to have Direct3D acceleration (not available) and the game couldn't run. I solved that by enabling the 3D acceleration at my VM settings. Now the game runs, but when it's time to play I just see a black screen.

Using the dxdiag tool and testing Direct3D fails, this is the error log:

Test results Direct3D 7: Failure at step 8 (Creating 3D Device): HRESULT = 0x8007000e (Out of memory) 
Test results Direct3D 8: Failure at step 32 (User check processing Direct3D): HRESULT = 0x00000000 (error code) 
Test results Direct3D 9: Failure at step 32 (User check processing Direct3D): HRESULT = 0x00000000 (error code)

I think the problem is there or I need to enable the texture acceleration. Any ideas?

Thanks in advance.

If you install the "Guest Additions" on that VM windows you can get 3D, is a prerequisite for use that function, but not wait miracles. Here is how you can install it:

In the "Devices" menu in the virtual machine's menu bar, VirtualBox has a handy menu item named "Insert Guest Additions CD image", which mounts the Guest Additions ISO file inside your virtual machine. A Windows guest should then automatically start the Guest Additions installer, which installs the Guest Additions into your Windows guest.
