Hello guys.

I'm facing the problem, when I cast flamestrike, FPS on my non-master windows dying at all, I guess the problem is not my PC, because I have really decent one and playing on lowest graphic settings.

Feels like something limits non-master window when load too high (like flamestrike casting), but where can I turn it off or make load balance for this?

Because I end up skipping Arcane Explosions casts during this lag, also priest can't shield or heal anyone during lag and I can't even sit drink on the alts while ground from flamestrike persists. I endup dying sometimes because of this, it was the same when I was playing MMMMP, but there were too much dmg, so I was ignoring it.

Here is the video, so you can see and it is not even worst example, sometimes fps dying harder and longer.

Please help! Mb if there is no way to load balance it, is there way to turn off flamestrike animation or change it?

Thanks.
