Issues, Workarounds & Localization

Hey everyone.

I got an issue with multiboxing.

I run several accounts, and if i open any window (Even just character info) it feels like it's loading it on all my clients, then shutting it down and reopening it, for the amount of clients i got running.

If i run a solo client i don't have this issue.

I've got a GTX 660, 8GB RAM, and an AMD 6100 (3,3 GHZ Six Core).
I've been monitoring the amount of CPU/RAM Eve is dragging.

CPU is usually between 20-40% with a few exceptions where it jumps. (Which happends when i open a new window)
Besides that my RAM is quite stable.

What do you guys think the issue is?

This only happends when i open a Window in-game. It does not occur during combat or loading.

Thanks in advance.
