Our server uses Item Frames above each item we sell. with our shops holding about 300 Items Frames.
I noticed an ENORMOUS amount of lag and didn't understand why. the only thing that I had done in that day was creat the shops. I took down all item frames and the lag went away. my FPS with the item frames was 5 FPS....without, average 40-50.
The kicker is that the most lag happens when you look toward the direction of the shops. it is an instant drop fro 50-5 FPS.
I know this is a major issue with others, even listed here. But honestly, this needs to be fixed. most shops on servers use item frames and this is a debilitating issue for a server. It costs money to run servers, and money is being thrown away as long as this issue is around.
1. place item frames...empty or full, it doesn't matter I notice the lag start at about 80 and up.
2. stay in the area or go away from that area and look in that direction...LAG CENTRAL.
3. Try and understand how this game is harder on my computer than cray high graphics games that don't lag at all.
