OpenVG Performance

Hello folks,

 

I've been playing around with the gpu-sdk1008 from Freescale.    I am running the 2.6.35 kernel from the 11.09 BSP for the I.mx53.  I am running the samples using the framebuffer  (no X11).  

 

The OpenGL ES1 and ES2 samples run beutifully with >= 100fps.   The pinball example running from the Ubuntu image seemed to run equally well, although I dont have the FPS numbers from that.

 

However, when I run the OpenVG samples, they only give me 20-25 fps.    Putting in some simple time measurements, it seems that PS_render takes ~45-50mS to render the tiger image for each frame.    Also, if I run the OpenVG pageflip demo, it performs even worse at around 11 FPS.  

 

Anybody have any clue as to where the problem may be?  Should I just avoid using OpenVG?

 

Thanks for any help,

Mark
