Hi Lionel, AFAICT there's been no change in Pigment that can have triggered such a slowness problem in Elisa. It seems to me like your driver is switching to a software path. Did you recently update your Mesa/DRI open source driver? Were you using the proprietary ATI driver before?
Regarding OpenGL ES, Pigment has a plugin to run over that API but it's only dedicated to embedded systems that are shipping most of the time without OpenGL support. For ease of development, memory consumption and speed reasons, people working in that market only ship (proprietary) OpenGL ES implementations. AFAIK there's no hardware accelerated OpenGL ES implementation for the desktop, apart from the Imagination SDK dedicated to developers. And anyway, OpenGL ES is not really meant to be used on the desktop. Regards.
