How many cars could I expect to host reliably with 512/128 ADSL?
Thanks!

512 up or down?
hehe, bad reader. I can host to 12 persons on my cable connection, which is
1024/128, so i think you can do the same, the upload being the most
important factor.

Hi Guido,
Thanks for that! : )
Only 12? I can do 12 with GPL on my 512/128 - I thought that Nascar would
of improved alot (especially as it can do a maximum of 43 compared to GPL's
20).
I don't actually want to host (although I may do at some point). I was
looking for something to aim for when tuning my multiplayer code. The idea
being, if I can host a Sirocco race of 12 drivers on my ADSL then a T1+ line
could easily hold perhaps 30 or 40. I have had some very good results with
warp / lag smoothing - only with 2-3 cars at the minute (without trying to
reduce the amount of bandwidth yet).
Thanks for your help,
All the best,
Ash

NR2003 requires around 2.6Kbyte/s (21Kbit/s) pr. client.
GPL only requires 1.6Kbyte/s.
Thats upload, download is only around 1Kbyte/s pr. client.

Thanks Karsten, thats handy.
Do you happen to know the frequency of the updates going up or down by any
chance? I want to see if I'm within the correct range.
I have managed to get very smooth updates running at 10 updates per second
(for both the client sending and server). We are trying to reduce that to
perhaps 5Hz with a better smoothing algorithmn. I guess the client update
could be up to twice as frequent as the server update (as normally the
server will have up to twice as much download frequency).
Sorry just thinking out-loud really :)
Thanks!

Thats excellent news, so I am in the correct ballpark (perhaps even using
less bandwidth!) and getting good results :). Still alot to implement, but
for now, i'm happy :)
Thanks Karsten

P.s. Default packetsize in Nascar is 116. In GPL it's 84 + a 54 byte header.
Guess the header has the same size in Nascar, cause that adds up to
2.6Kbyte/s.
(116+54) x 15 = 2550bytes
The 84 bytes in GPL is enough to show 4 cars ahead, and 1 behind.
In Nascar it is 5 ahead and 2 behind, I think.
