[GEM-dev] Problem with textures on Ubuntu

[Jack]

There is 512 MB of memory on the GPU.
All informations are here :
http://www.notebookcheck.net/NVIDIA-GeForce-9700M-GTS.9899.0.html

However, there is something very strange if it's about memory because  
on my MacPro 2x2.66 GHz Dual-Core Intel Xeon, i have only 256 MB on  
the GPU and all works fine on it (only 2 fps but it is not so slow).
The size of the images are between 127x108 and 72x123 pixels (so the  
total size at 24bit is near 12 MB ! : 127x108x3x300/1048576 = 11.77 MB).
Even with 100 images it is slow (but it seems good with 50 images).
I needn't to create my Gemwin and turn on rendering to have this  
problem.
I give you the main patch and the abstraction here.
Thanx for the help.
