Pretty off topic but I have to say it ;) All PCs with UMA had the worst
performance. I though "what were they thinking" when I heard about that!
Major design criterion for consoles has always been fast _graphics_ and
UMA is one of the slowest concepts (nowadays).
I always wondered why they don't make special graphics DRAM. Nearly all
accesses to DRAM-cells are read-write cycles (reads are destructive and
writes have to read the not-modified cells of a row). Why not make it
read-modify-write to allow for example "writing with alpha channel".
When I heard that PS2 has its DRAM directly in the graphics controller
with an ultra wide bus I directly though: Yes, that's how it should be!
You can do marvelous stuff with that. (Don't know if they really do,
though. I hope they will someday release some real documentation.)
Ok, that's all *g* Back to Lua stuff.
