I'm running X2 with Maserati on Win 8 and have no issues whatsoever...
I used Maserati under X2 in Win 7 with no issues and that was on
an AMD A6 with 8 gig RAM!!! Not an i7....
I now have an A8 with 16 Gig....
I use ALL my Waves plugins, with BOTH operating systems without
any issues...
My biggest issue....Kramer Master Tape is a CPU hog...but that's still
able to be gotten around.
Don't know why it would be giving you issues...
