I am having problems with on line gaming (Dark Age or Camelot)since building a new pc. The old one works fine, but the new one does not.
Both pc's are connected to a dsl connection using a 4 port linksys router.
I started out using the on board lan (ASUS A7N8X deluxe MB), and when that gave me problems took the Linksys ethernet card out of older pc. Disabled all except the Linksys. This did not help.
The problem is everything in the game is very smooth, it is just that objects that appear to be near are far, and ones that appear to be far are near a lot of the times.
A friend of mine told me it sounded like a networking problem (packet loss). Does anyone have any idea what could be causing the packet loss?
The older pc is fine, and the newer one is having this problem with both of them connected to the router. Any help would be greatly appreciated. If you need more details please ask,,,, it is driving me crazy trying to figure out the reason for this problem. Thanks

its not packet loss

packet loss is just when some of the data being sent to server/client and client/server is lost. its then just retransmitted. This does create latency known as lag. now if you laged would know what it is...

First I suggest you ping the server you play to (you should find the ip on daoc site) and see what the latency is. if its above 200 then yeah u got a problem..

Other then that it just sounds like a video error to me.. I dont see how your friend came up with packet losses lol.. Try getting the most up-to-date video driver for your card.

Also make sure your settings inside the game are correct. I know for a lot of 3d type games you can change the settings to see how far you can look out (like as you move you see lines of the object but as you move closer you can see the building. if you reduced that amount you wouldnt see the lines untill your pretty close. so make sure it isnt that too..

Well, actually it depends on the game. Many games stream UDP packets and allow users to set their update times (within a range). Packets may be lost only because they are outside the update window (the time within which the client has chosen [you don't always get to choose] to send a response). In this way things still move.

Retransmission is often avoided because usually the game is programmed to drop packets which have no relevance to the current time window. Still retransmission occurs at seemingly random points according to the programmer's manipulation of the protocol. Of course if all else fails, your final exception in a loop will be to fall back on the standard and retransmit, drop, or start over.

That said, packet loss is not an answer to what very much sounds like the video card and/or the game. Find a new driver, maybe a game patch.

Hmmm - exactly my problem too, 2 DAoC-playing computers with 2GB CPU's & 1GB RAM going through an ADSL router. And yes - I built the problem pc myself, too (it works fine otherwise).

DAoC works perfectly on pc with NVIDIA nForce MCP network card & Radeon 9600 graphic card, lags badly with Realtek8029 & GeForce4 MX420 combo.
Don't know if it can be trusted, but DAoC has an inbuilt performance indicator(Activated by shift-P)and the packet loss indicator there (The P-marked button) goes red all the time on my problem pc, never on the other. This corresponds very well with the lagging, and I noticed the character itself does not lag, but rather that fast-moving objects around him are not displayed in their "proper" places. Thus, I am pretty sure that packet loss IS the problem.

Not sure how to deal with it though. Guess I cant blame the graphic card, but have updated all drivers and tried another nw-card(same type - Realtek) & changed network cables without success.

Advices would be appreciated...
