comment Compress / make Blender .obj file smaller
You will have to decompress the file in software before rendering no matter what, so i don't see a point to this TBH. What exactly causes the crash? Also, as Luis pointed out, a 2MB .obj file is fairly big for an iPhone app.

comment How should IDs be assigned in an entity component system?
It's expensive enough though. CBES shouldn't introduce overhead, this is why Artemis does all the tricks it does. If you're only going to use CBES for something like the player or a monster in an MMO, then sure it's probably fine to use a dictionary, but usually CBES is used for everything from a few massive buildings to lots of tiny particles. These things matter.

TBH i don't see a point to this, you're introducing a lot of overhead for nothing. Hashing is an expensive operation, dictionaries are expensive data structures, strings are as well compared to integers. If you don't want to use arrays, it's better to just use a list.

comment Is it possible to render part of the screen in different pixel density using openGL?
I doubt you can do that. You can cheat the looks of it by rendering to different frame buffers depending on the resolution you want and then putting the image together, but that's not an optimization. What you want is Level of Detail. Models with reduced polygon counts, mip-mapping, etc.

@DanielSunYang I just saw the edit, so nevermind :)

comment Canvas animation drops to 30fps every 3-4 seconds
@DanielSunYang The demo you linked had a massive memory leak, i sincerely doubt that Chrome's the issue here. I'm just saying, if all you did was restart Chrome then your problem is not fixed.

comment OpenGL vs DirectX difference from Graphics card perspective?
@SRN It does in backwards compatibility mode. OpenGL 3.3 works on cards released before 2010 as well. If you want to use new features then of course it won't work.

comment XNA C# Platformer - physics engine or tile based?
@AndrewRussell I've not "turned it into" anything, this is what i was talking about from the beginning. It's not silly. We use words to communicate on this site, the semantics matter if you're trying to get a point across. Again, it'd be nice if you'd edit the answer, the latter two examples have some actual merit.
