C++ zero initialization - Why is `b` in this program uninitialized, but `a` is initialized? - Stack Overflow
Declaring constructor with `Bar();` is not equivalent to using `Bar() = default;`, even if you later define with `Bar::Bar() = default;`

D3DPOOL_MANAGED is not a valid pool option when using Direct3D9Ex
> There's no lost device scenario when using Direct3D9Ex, as well as some
other behavorial changes (VRAM is 'unlimited', etc.)

This change can break D3DX functionality ( https://stackoverflow.com/q/8540526/ ). This 'more managed' approach to device-loss is continued by subsequent Direct3D versions. OpenGL has no concept of device-loss at all.

The Evolution of Direct3D
from https://softwareengineering.stackexchange.com/a/205795/

> Playstation 1 optimized for this problem by using a 3D hardware solution that did not rely on a memory intensive data structure called a Z-buffer, instead they used a polygon level sorting algorithm that produced ugly intersections between moving joints.
> [.....] the simplicity and elegance of Z-buffers to game development were worth the risk that consumer 3D hardware would struggle to affordably support them early on
> [....] It was reasonably believed at that time that Intel deliberately dragged their feet on improving PC bus performance to deter a market for alternatives to their CPU’s for consumer media processing

Is it true that having lots of small methods helps the JIT compiler optimize? - Stack Overflow
As HotSpot is not trace-based, it seems it conceivably could. Profiling and compilation is at the method level, and no finer.
