I don't think this is desirable. Every single program uses devdraw directly. Rio is just another devdraw client. > If you use devdraw as a framebuffer than the only > functions you need from devdraw are initdraw, loadimage and flushimage > which internally use memdraw and memlayer in a way that decreases > performance.

Then don't use it as a framebuffer -- Framebuffers are *already* a poor fit for modern hardware. Create an image, draw into it, and reuse it. The devdraw model, where textures are uploaded and reused, isn't ideal for modern GPUs, but it's far closer to what is needed, and far easier to accelerate, than software rendering. > So by defining a lower level we could improve the > performance of rendering by a factor of two. While tying tying the code to an unaccelerated model that is not usable over the network. ------------------------------------------ 9fans: 9fans Permalink: https://9fans.topicbox.com/groups/9fans/T2518f9e4fc10ed03-M2d6d6b65ad50c111a018633b Delivery options: https://9fans.topicbox.com/groups/9fans/subscription
