Crippling lag in Vale of Eternal Blossoms

[Mickthathick]

Hi all, I've been having issues with crippling lag whenever I am in (or near) Vale of Eternal Blossoms with my 5 man team.

I had a look at IB system settings, I changed the main window to max 30fps and background windows to 10fps (I have dual screen setup.) I also checked the CPU cores, I have 6 cores available with the slots 1-5 using cores 1-5 (6 is not allocated.) This didn't fix the issue though.

Basic system details:
AMD Phenom II X6 1100T Black Edition

VTX3D Radeon HD7850 2GB X-Edition

Couple of 500g hard drives (both almost full)

Old ASUS motherboard (bought it a couple of years ago, sorry details not to hand)

8gb DDR2 RAM (4 sticks)


Any thoughts on what I can do to fight this lag? I am at work right now but can post detailed system info if needed.
