* '''SSE4''' -- is Intel 2006 CPU extension consists of two subsets 4.1 and 4.2. GSdx only uses 4.1 set so you'll need Intel CPU with codename [http://en.wikipedia.org/wiki/Core_2#Penryn Penryn] or newer (E7xxx and higher for Code 2 Duos and Q9xxx and higher for quads). AMD Bulldozer and later support SSE4. '''Warning''': If you will try to use SSE4 optimized dll on unsupported CPU you will encounter a crash whenever the code reaches SSE4 optimized part (it may not happen for some time but it will occur eventually). | * '''SSE4''' -- is Intel 2006 CPU extension consists of two subsets 4.1 and 4.2.

The difference between these versions is not immediately apparent to the user. You won't see large FPS gains when switching from SSE2 to SSE4 but there are some parts in games that do benefit from these optimizations. The AVX versions only provide speed ups for the software renderer of GSdx. | The difference between these versions is not immediately apparent to the user.
