Anyone else disappointed by the lack of double (and triple) buffering? It all comes to just having a larger framebuffer for faster graphics operations. A lot of special effects and filters can only be implemented fast and correct using more video ram.

The only other thread I could find on the subject is:

I've used the Lua array method, but it's notably slower than video operations.

I guess this is just a hard limitation so one doesn't sink too much time in chasing these sort of thiings, like having too many colors / channels of sound?
