It's not really that bad either, I can open up Minecraft at
any time and have it sit in the background quietly using
~800Mb ram and virtually no cpu time.
Either your kid has tons of mods in their Minecraft or your
computer is a bit dated.
Now compare that kind of resources consumption with any game
based on Quake III engine. While you are at it, compare the
graphisms. Still not convinced ? Measure latencies, which are
critical for most games.
People always compare things to Minecraft when discussing if
garbage collection is feasible in a game. Which is annoying,
because I'm sure Minecraft's allocations would make most people
sad. It's not a fair comparison.
Some quotes:
"Minecraft 1.8 has so many performance problems that I just don't
know where to start with. Maybe the biggest and the ugliest
problem is the memory allocation. Currently the game allocates
(and throws away immediately) 50 MB/sec when standing still and
up to 200 MB/sec when moving. That is just crazy."
But that was just a one off thing for 1.8 I believe, the normal
is much better:
"How did that work in previous releases? The previous Minecraft
releases were much less memory hungry. The original Notch code
(pre 1.3) was allocating about 10-20 MB/sec which was much more
easy to control and optimize."
10-20 MB of garbage every second. That's just ridiculous to think
of in a language like D. And that was long ago, it's probably
worse now. Luckily D has things like ranges and other ways of
improving this.
