Lag caused by home point, bard songs, light glows and other things are a driver issue usually. The effects are so old the driver doesn't know how to handle them properly so it lags out.
Most people probably never get lag at all around home points.
I dont know if i agree with this. it seems something ppl repeat without any proper testing or evidence for it.
E.G. the chatlog is a huge cause of FPS lags in the game.. the game is just poorly coded and hits single core utilization fast.
Just some prelimary testing done
Tavnazia Homepoint 1
Original 161-179 246-296
Pink Crystal 181-197 287-317
Runic Lamp 184-199 285-317
The first sets of numbers is the FPS range with the chatlog on.
The second sets of numbers is the FPS range with the chatlog off.
This is in a remote place with no mobs or players in the zone so nothing really changes between the testing. its very clear that something like the chatlog is just eating up FPS.
This is with battlemod running
