Game pauses input every 3 seconds since patch

The graphics is running at 45 to 50 fps. Nothing pauses there. Any input from the keyboard or mouse works for 3 seconds then pauses for 1. Does this over and over.

If running then stop and if paused, my character keeps running then after pause jumps back to were she should be. Running and turning is the same.

Text is the same. Inputting it into chat box and it pauses then catches up.

This started last night after installing patch.

How is your CPU-usage when this happens?

that happened to me to i thought it was just lag havent loged in today though

Thanks for replies, did log on an hour ago and the problem has gone. I have a Core 2 Quad Q6600 at 2.4 ghz, while playing FFXIV it runs at 55 Deg C and all cores are working and total use is from 60 to 95%
