Re: RE: Very slow graphics rendering   
Sorry that I wasn't very clear.  I am not asking about the patch.  I was wondering if a driver from the MX35 (thirty-
five) BSP could be used because they both use the same AMD Z160 graphics accelerator.

RE: RE: Very slow graphics rendering   
In general the QNX 35 display controller driver does not have 2D acceleration.

The best bet is to sort the image bpp, then go through support to explore optimized software approaches, any other 
available patches, and possibly CE to add a blitter to the display control driver.

Derek,

After converting any of the PNGs that lacked the alpha channel, and running our tests again, we don't see any noticeable
 improvement.  (the majority of the images were already loading as 8888)

So assuming our driver is indeed in 8888 mode (I'd still like to know if there's a way we can directly verify what mode 
the video driver is running in, just to be sure), the bpp does not appear to be causing the slowness we see.

Thanks,
Don

Derek,

Oh, and also wanted to say I understand that we're still working on getting things optimized.  My pointing out that we 
haven't seen improvement was purely information, not a complaint.  I know this can be an involved process!

Thanks,
Don
