Thanks for the welcome people!

Well, I added in the fixed rate update after reading:

http://www.gaffer.org/fix-your-timestep

my version is not identical (I don't lerp states for instance) and to be honest - this is the first round of this going in - I will see how it handles before going further.

Here's the code I used:


void CTitle::FrameUpdate(float fTimeDelta)
{

// Add the delta to the record
CSystemInfo::AddFrameDelta(fTimeDelta);

// Clamp the delta if necessary
if(fTimeDelta > 0.25f)
{
fTimeDelta = 0.0f;
}

m_fAccumulator += fTimeDelta;

while(m_fAccumulator >= FRAME_DELTA)
{
m_fAccumulator -= FRAME_DELTA;


if(CSystemInfo::ShouldWeBeDisplayingAScrollingBackground())
{
CScrollingFullScreenQuad::Update(FRAME_DELTA);
}

if(CPlayer::GetStatus() == PLAYER_STATUS_ALIVE)
{
CPlayer::Update(FRAME_DELTA);
}

CEvents::Update(FRAME_DELTA);
CPathDatabase::Update(FRAME_DELTA);
CPathEmitter::UpdateEmitters(FRAME_DELTA);
CPathFollower::UpdateFollowers(FRAME_DELTA);
CActor::Update(FRAME_DELTA);
CExplosion::Update(FRAME_DELTA);
CEmitters::Update(FRAME_DELTA);
CParticles::Update(FRAME_DELTA);


}

}
