As I said, it's minimal. and they don't support partial buffer updates with buffer age - we do. we use advanced features drivers offer. it happens to work amazingly well on other drivers (mali, even rpi's vc4), but nvidia seems to have glitches where it starts reporting incorrect buffer age... the automatic vs invalidate above forces evas to cease listening to the driver and what it reports and just ignore it (which is almost certainly what everyone else does as they likely dont even have the support). > ///Peter > > ------------------------------------------------------------------------------ > Developer Access Program for Intel Xeon Phi Processors > Access to Intel Xeon Phi processor-based developer platforms. > With one year of Intel Parallel Studio XE. > Training and support from Colfax. > Order your platform today. http://sdm.link/xeonphi > _______________________________________________ > enlightenment-users mailing list > [email protected] > https://lists.sourceforge.net/lists/listinfo/enlightenment-users > -- ------------- Codito, ergo sum - "I code, therefore I am" -------------- The Rasterman (Carsten Haitzler) [email protected] ------------------------------------------------------------------------------ Developer Access Program for Intel Xeon Phi Processors Access to Intel Xeon Phi processor-based developer platforms.
