Actually, it is true that it displays the last value under 1000fps. From
vgui_netgraphpanel.cpp:
void CNetGraphPanel::UpdateEstimatedServerFramerate( INetChannelInfo
*netchannel )
{
float flFrameTime;
netchannel->GetRemoteFramerate( &flFrameTime,
&m_flServerFramerateStdDeviation );
if ( flFrameTime > 0.001f )
{
m_flServerFramerate = 1.0f / flFrameTime;
}
}
m_flServerFramerate is what is displayed on the netgraph (see
CNetGraphPanel::DrawTextFields) and m_flServerFramerate is updated only if
flFrameTime > 0.001 (i.e. less than 1000fps). All it takes is a single frame
to take longer than normal for you to dip below a calculated 1000fps which
may explain why you see it getting stuck at values the server never seemed
to report.
There is no integer overflow as far as I am aware.

Subject: Re: [hlds_linux] High FPS?
Pretty much what Tony said expect it doesn't seem to be true that it
displays the last value under 1000 fps, as it often gets stuck at values the
servers never reported. We suspect that there is also an int overflow in
play here which makes the output totally meaningless.
Alternatively it could well be the server is reporting some other
measurement of fps which isn't consistent with the actual achieved fps due
to a measurement error introduced by the high fps.

Steve
