High or Unstable Pings

[Guest achilleez13]

Hi all,

I hate to come on here and moan because I absolutely love this sim, since I bought it a month ago others are uninstalled and it's now all I drive.

Unfortunately though, recently I've been getting very high pings.

I'm in the UK and I'm getting in the region of 500-650 to S.America/Australia and 150-250 to European servers.

What's strange is that yesterday, all day, the ping seemed to normalize, with the highest being 250 to Brazil (which is probably what I would expect on 2Mbit ADSL) and 50-70 to Euro servers.

However I logged in this morning and pings have more than doubled again.I'm now worried to drive online as I fear I will cause crashes due to lag.

Is anyone else getting this? Is there anything I can do to help the problem?

Any help/answers much appreciated.

I'm also getting some inconsistent car behaviour lately. But I'm not 100% convinced it's netKar causing the issue. Had a few cars slow to react or warping around the track even with very low pings. But there are other factors involved which could cause spikes in bandwidth availability.

Watching the replay of other drivers with pings around 50, they do not appear smooth at all. But maybe that's an issue with the replay fidelity.

You could try running a ping out of game and then a trace route and see if there's a difference in the ping in / out of game or a bottleneck (or too many hops) between you and the server you're trying to connect to.

Here's one from my home to my server at work.

PING

1.Get the servers IP address from the list.

2.Open a command prompt

3.type "ping [server ip]"

TRACE ROUTE

1.Get the servers IP address from the list.

2.Open a command prompt

3.type "tracert [server ip]"

So this is a nice fast ping response with only 8 hops between my physical PC on 192.168.1.1 and the server on 116.212.215.110. So I should have no lag issues at all on this server (unless the other player has a poor connection to it).

If I try the same thing to the netKarCentral.com server I get pings so high and so many long latency hops that I know not to bother connecting. It's just going to be too slow. That's not a fault of the game. Just our cr@ppy internet in Australia.

Also just be aware that some firewalls might block ping or trace route packets so you may not get any reply or receive a timeout message.

Hopefully this helps you a bit (and hopefully you're not an IT pro thinking why is this n00b telling me this basic stuff )

Good luck
