Should program use 85% cpu?

My project linux outdoor hunter , using code simular to aliens, is using about
85% cpu resources. Is this normal?

Depends on what your system is. If it’s a fairly decent configuration, I’d
say that (A) it’s ridiculous (B) you may have gotten yourself stuck into
some sort of ugly loop somewhere, so that instead of blitting a deer once
per frame, you blit it sixty thousand times/frame.

Rethink things.

If your blitting as many frames as you can per second then I would say 85%
is pretty normal.On Thu, 18 May 2000, Nicholas Vining wrote:

As long as the X server takes the rest. Otherwise he’s wasting 15% CPU
doing nothing.

My attitude was that as far as I know, he was just blitting a few sprites on
the screen, which shouldn’t gobble 85% of your CPU resources. From what he’s
been saying, it doesn’t sound like it should gobble 85%.

I didn’t see the code but if he show just two sprites on screen as
FAST as possible it could take these times.
But the normal thing is that the time is taken by the X server.
