Avast 8 and AMD

My wife’s computer runs an AMD processor with Windows 8, I thought I read somewhere that could cause a problem with the new Avast 8 and AMD. Is this true or am I confused about that and btw I installed it on my Windows 8 i5 3210 and it is great!

Thanks

The AMD thing is in reference to the video card http://forum.avast.com/index.php?topic=116242.msg902806#msg902806
