Default Video Memory & System Memory mix problem

Hi all,
I have this problem: when I create a a lot of textures the system monitor show me that my application use a lot of system memory, but the textures are allocated into the video memory, right ?

I don't know where is the mistake or bug. If someone can help me, thanks ....

Attached to this post there is a simple example program, that allocates a lot of textures to better see the problem.

I use Fedora 14 with rpmfusion driver (260.19.12) on
01:00.0 VGA compatible controller: nVidia Corporation GT218 [GeForce 310] (rev a2)
board with 2.6.35.6-48.fc14.i686.PAE kernel.

Thanks in advance.

Default Re: Video Memory & System Memory mix problem

I can add a screen shot, with running application and system terminal.

As you can see, the system show the "test" application with a ~520Mb memory used, but
a lot of this memory is not system memory, but video memory.

Someone have the same problem ?

The effect is that when I go over 2Gb (my system memory) with other applications, the SO start using swap space but this isn't correct, because I haven't use system memory ....

Thanks in advance.
