difficulties with #OO in e.g. #C++ when programming #video-games for the #PlayStation 3 in 2009. Unfortunately these are slides. Basically the author’s claim is that C++ encourages memory layouts that have terrible #performance on modern hardware. Very concrete, with lots of C++ #examples and PowerPC #asm disassembled from them of 3-D programming and diagrams of #cache line evictions and whatnot. Basically his recommended cure is to use #parallel-arrays for most things and “flat” contiguous level-order tree linearizations for tree data.
