I understand that there is a texture cache for QImages too when rendering to OpenGL context. Is there still real performance difference between the two?

It's especially the case for mobile devices where even though We don't want that kind of trade-off.

So it's a This is a very board statement. GPUs are very good in some things and bad in others. I don't think rasterizing a typical web page is in the first category. I have yet to see anything that would convince me otherwise. > combination of factors, if you end up using GPU's through and through you > optimize for power usage, memory consumption and more often than not speed, if > you end up using CPU's you usually optimize for the quality of rendering and > simplicity of usage. The key is to figure out the right ways to utilize the GPU. antti _______________________________________________ webkit-qt mailing list [email protected] http://lists.webkit.org/mailman/listinfo.cgi/webkit-qt
