I'm wondering if anyone has tried this and has any opinions on it? I am trying it, in the hopes of improving the match between a player's real location and their location as displayed by the client, as I am finding it challenging closing with moving player characters on my characters that use melee weapons. I know that sometimes raising process priority can actually hurt an application's performance, and sometimes lowering the process priority can improve performance. Does anyone have any experience with this in UO? For those who don't know what I am talking about, each processor in your computer can only process one command at a time. The operating system assigns priorities to processes. A process is not exactly the same as a program because one program can have multiple processes. A process is like a linear forums thread, a string of linked commands - if I am not describing this well, please forgive me, I am self taught and my knowledge of technical terms is a bit shaky at times. The operating system assigns priorities to processes, and the processor processes commands from those processes based on their priority (I think I might deserve an award for the most uses of the word "process" in one sentence... ). So, for example, in Windows, a process with "high" priority would have it's commands processed before a process with "normal" priority. You can use batch scripts to start up programs with different priorities, or they can be set by the programmers that code the programs, or you can hit ctrl-alt-del and right click on the program in the list of processes, and change the priority that way - this is the only way I know of to do this with UO if you are using UOAssist. For the most part with Windows, each program will have one process.
