Hi, Long time reader, first post.

First of all, why no search options on this forum? Might stop a lot of the same posts over and over like I read.

Secondly, should power supplies have their own forum?

I have a USB Microsoft IntelliMouse Optical mouse (6000 scans per second). Will I lose any performance plugging it into the PS/2 connector?

That's all. Thanks for your help. :)

I think you will... USB is faster i believe...but i guess it depends on what type of game your playing if it will make a difference. If not used for FPS games I don't think it matters. I play delta force and I do notice a diffence especially when knifing.

The transmition speed on ps/2 is slower than USB, but I beleive that you won't see the difference because the mouse does not even use all the bandwith available to it when connected through ps/2.

The reason for USB mouses and keyboards is mainly the plug-and-play advantage.

In ancient times they had no statistics so they had to fall back on lies

I find USB to be slightly unreliable, and the performance difference negligable.

Accroding to tom's hardware review PS2 can handle twice as many exchanges per second than USB.

There is the link to the article.

I read the article you posted and now im a little confused when I test both my mice 1 with ps/2 the other with USB using mouserate I get a higher sampling rate with USB about 200hz avg...whereas with ps/2 I get about 120 hz avg?? It appears that using USB connection gives a higher faster sampling rate isn't this higher rate going to be better in FPS games? or am I mistaken?
