How much VRAM you need...

[Kompass63]

... minimum, to play a bootleg (Profile 'FULL') version of FF7?

For the 1998 version 4 MB of VRAM is specified as a minimum.
For the 2012 version no information on the amount of VRAM is specified as a minimum.
Pitbrat requires a GPU with 512 MB, but that seems exaggerated to me a lot.

GPU with OpenGL and Shader 2.0 support and at least 512MB (recommended Geforce 8800 or better) (Intel GPU's not supported)

I have a Dell Optiplex GX620 equipped with an ATI Radeon X300/X550/X1050 Series (128 MB VRAM).
The game works with it.

That it runs very slowly I attribute of the Singel Core CPU and not to the graphics card.

What hardware are you taking the game to run?

I can't imagine it needs more than an old Pentium processor and a 128 mb card.

It would interest me if there would be less possible ...

I'll see if I can borrow my dad's laptop this week and try to run a FULL profile on it. I believe it's a duo core 1-2GHz range and has a 256MB GPU.

It ran can be run on DX6 (possibly DX5) so I doubt the hardware requirements would be considered high by today's standards. I mean, this predates the GForce 3 ( which Doom 3 was showcased on) so I bet any modern integrated intel video card can run it in hardware mode.

The game will run for a time on less than 512MB of VRAM.  There is a memory leak in the OpenGL driver, so the less ram, the quicker to crash.  The new textures require a significant amount of VRAM.  For integrated graphics cards, avoid installing the field and battle textures.  Intel HD GPU's struggle to run a fully modified FF7.  These cards have varying amounts of VRAM available depending on the system.  Results will vary.

Well if there's a memory leak then that would explain why it seems a little high.
