==== WARNING... ignore this in Scratch 3 !! ==== Due to the way Scratch 3 works, the timings don't actually make much sense if you're using Scratch 3, so you can no longer make any sensible judgements about bitmap vs vector from this project... ==================================== MORE SPEEDTESTS: http://scratch.mit.edu/studios/795672/ ------- This is it! - The one you've always wanted! :) Which is faster? Which should I use? Vector...? Bitmap...? The answer is actually not so simple - it really depends on how complicated the vector costume is and what you're doing... Basically, the more elements a vector costume contains, the longer it will take to perform operations (esp. switch, rotate, ghost). Very simple vector costumes are actually a bit *quicker* than the equivalent bitmap! However, it doesn't take much for vector to become slower. In the end, I guess you have to decide for yourself, in each project and for each costume, whether the extra quality from using vector will be worth the slowdown it could cause. NOTE: I've only used ghost effect here in order to avoid the newer Stage3D player - this is all the original player.
