I have to say that X2 64 has been ROCK SOLID. Even more so on Windows 8,
as the Core usage has been leveled. All cores work more evenly, and hence, gives
more stability. At least that's been my experience so far. I haven't had a single
crash since upgrading to Windows 8, and I'm using BOTH 32 bit and 64 bit plugins. I've had some anomaly's with the 32 bit plugs, however. But everything else has been solid.
If the forthcoming Win 8 X2 patch improves performance and compatability.....TOTALLY AWESOME!
