I mean I lag like dog shit with a decent-ish computer on 32bit using tyrael since MoP has been released. Are they any plans to implement this
you would lag with tyrael using 64bit too. and no theres no plans to support it. ive made tons of posts all over the place about why, if you wanna know the exact reason track one of them down.
When I use any CR with Tyrael I Always open my task manager and set the WoW.exe priority to "Higher". It reduces the FPS drops significantly, for me at least.
