Render pipeline efficency update #38

Open rcmaniac25 opened 9 years ago

rcmaniac25 commented 9 years ago

Investigate and test efficiency updates that are transparent to developer.

Async graphics loading (think Doom 3: BFG)
Material handling (if multi-part Model, but one material/RenderState/Pass/Effect, then it should iterate through passes THEN parts. Currently it defaults other way [iterates through parts, and keeps rebinding the passes])
State changes (Make sure state-switching doesn't happen to already bound elements [this way dev-done grouping works properly])
