    Your GPU has Intel's DVMT (Dynamic Video Memory Technology). It is supposed to automatically allocate memory as needed by the graphics hardware. The upper limit for Intel GMA 3100 is 256MB (minus any overhead), but Unity is seeing the minimum allocated. It should increase as Unity uses it.

    If it doesn't, try going into the BIOS and checking for a setting. You might be able to force it to full size.

    To clarify, Intel GMA 3100 does not have any video memory at all. It uses some chunk of actual system memory. So yeah, that "VRAM amount" is a very slippery term in case of integrated GPUs. Technically correct would be saying "0MB of VRAM" on Intel 3100...
