Hi, I'm trying to write a simple UDP client application which receives UDP packets from a server, each the size of 384 bytes. Unfortunately, I'm encountring what seems to be client-side packet loss, which gets only worse when multiple threads are added to the application. This is not a result of high CPU usage, since the CPU usage is only a few percent. I can only assume that the packet loss is a result of context switching done by the OS, and my application not being able to receive the packets on time. I'm using VC++ on win2k, and the winsock2 functions in the platform SDK to create a socket and receive UDP packets from a specified port. I've tried setting the process & thread to time critical, which does have an improvement, but the packet loss continues. Is there any way to avoid client-side UDP packet loss ?? Ideas / code examples would be greatly appreciated ! Danny
