As the old saying goes in tech support: "It works fine for me."
I have none of these issues. But then I am using two brand named systems. One is a Toshiba laptop with 64 MB GeForce 460 and the other a Dell with 256 MB ATI 9800 XT. I even have the game running on a laptop with an ATI IGP 9100 chip, which is about as low end as you can get for graphics support (except for the Intel and SiS

.) All hardware and drivers (mobo, net, sound, video) are not OEM, beta nor special release and are up to date and installed as per instructions from the manufacturer.
With systems as complex as WinXP and Ryzom any slightly misbehaving component/driver can cause problems. There are a lot of places that can cause things to be problematic:
- A slightly damaged or loose network cable could cause things to screw up.
- Some players on cable modems have not been able to play Ryzom during the peak times in their neighborhood due to the way their ISPs manage things.
- Don't use hibernation mode when shutting down a system, when it starts up again the network hardly ever reconnects properly.
- Sometimes a piece of networking equipment belonging to an ISP is misbehaving. Pingplotter can help see things of this nature.
- Reseating and dusting out the cards/fans/cables in your system may help.
- We have seen issues with RAM modules that were marginal at 400 MHz but worked fine at 333 MHz for Ryzom.
- CPU and video fans that work fine for the majority of things but start to fail under Ryzom due to the load should be cleaned or replaced. I had to replace the original fan on my ATI card due to it becoming dusty and slow. The dieing fan did not affect other games.
Things are not simply 'Ryzom sucks.' If that were the case then no one would be playing. Each game is unique in how it handles graphics/memory/network, so saying that 'WoW works' or 'BF2 works' says nothing. I have seen complaints on their forums about players having issues connecting and playing.
