why does opengl use 4 to 8 times the vram compared to directx ...

When we forced my PC in openGL mode, the mem usage of the mac was pretty much thesame as on the pc (20 to 40).

So my questions are:

Why does openGL use so much texture mem usage? (its *8 at most points).
How can we properly  fix  this?

Is it causing a problem? The file size isnt any worse? This is only while running? To me, it sounds like DirectX is not properly detecting available memory. In theory, OpenGL is running faster/cooler as a result.

No its not causing a problem (yet?), we just tested on iPhone 4 hardware.

The file size is the same.

I guess this is only while running. When running I can see the VRAM in the stats window.

DirectX not properly detecting available memory, is it possible to authenticate this so we can mark this as the cause of the problem?

Id check to see how the textures are compressed in each case.
