I'm in the early stages of building a little game with OpenGL (in D) and
I just want to know the facts about the GC before I decide to either use
it or work around it. Lots of people have said lots of things about it,
but some of that information is old, so as of today, what effect does
the GC have on the smooth operation of a real-time application? Is it
pretty noticeable with any use of the GC or only if you're deallocating
large chunks at a time?
Some tips:
- Avoid allocations if possible
- Use buffers/preallocated memory if possible
- Disable the GC (collection only)
- Use allocators instead of e.g. new
- -vgc is awesome
If you are using GC to allocate (not really a good idea), run collect
when you have some spare cycles.
Can't really say much about the current GC implementation. But what I do
know is for real time apps GC is not a good tool for memory management.
