    Hi, 
    i have a quite simple question, hoping someone of you has an answer to it:
    Does Nokias  S60 devices with PowerVR accelerator ( like N93, N95, N95 8GB ) its own graphics memory ( in hardware ) or are they sharing the memory with executables memory?

    Best Regards,

    They all use a unified memory architecture, RAM is shared between CPU and GPU.

    Thank you for the answer.

    But anyway, GL is doing a copy of vertex data, to gl server. Right?

    So with unified memory architecture, will it help to load the arrays to VBOs, to reduce memory consumption?

    It is generally a good idea to use VBOs for static vertex data. However you will not see much of a difference on devices with PowerVR MBX, even with UMA.
