Re: [Chromium-dev] NV_pixel_data_range

[Mike H. <mho...@gr...>]

So far, the performance difference is minor, about 10%, and it is a pain 
to use, but I haven't tried the newest linux driver as of two weeks ago.

The problem is the type of memory that you must copy into has to be 
"special" memory and then when you try to send it across the network for 
composite, you get nailed.

I, and many others, are trying to lean even more on Nvidia/ATI/3DLabs to 
fix this.
