Do you use D's GC?

[russhy]

Generally GC is not an issue, until it becomes an issue

Use it with caution or manage things by yourself

The most important thing to do is to know exactly what you need, 
and when

Avoid heap allocation during hot loops at all cost, no matter if 
it's GC or malloc, they both slow

Remember frame budget is only 16ms per frame for 60FPS, stutters 
are not an option if you want a smooth user experience

And if people use 120HZ monitors, or 144HZ, then the frame budget 
becomes even lower

GC is faster at allocating memory, but collections induces pauses


As other said D is great at providing tools to avoid GC, so use 
that at your benefit

And as i said in other posts above, control your memory 
allocation strategy from the start, and things will be easier to 
manage
