For DirectX 10 mode you will need a DirectX 10 capable card (NVIDIA GeForce 8000 series or ATi Radeon HD 2000 series at the least) running under Windows Vista or Windows 7.<br /> | For DirectX 10 mode you will need a DirectX 10 capable card (NVIDIA GeForce 8000 series or ATi Radeon HD 2000 series at the least) running under Windows Vista or Windows 7.<br /> | ||
Don't forget to update your DirectX ([http://www.microsoft.com/download/en/details.aspx?displaylang=en&id=35 Web installer], [http://www.microsoft.com/download/en/details.aspx?id=8109 Runtime package]) specifically if your PCSX2 does not want to work demanding to update DirectX or complaining about some missing dlls.<br/> | Don't forget to update your DirectX ([http://www.microsoft.com/download/en/details.aspx?displaylang=en&id=35 Web installer], [http://www.microsoft.com/download/en/details.aspx?id=8109 Runtime package]) specifically if your PCSX2 does not want to work demanding to update DirectX or complaining about some missing dlls.<br/> | ||

In most cases you'll have several dlls for each GSdx version. '''SSE2''', '''SSSE3''', '''SSE4''' and ''' | In most cases you'll have several dlls for each GSdx version. '''SSE2''', '''SSSE3''', '''SSE4''', '''AVX''' and '''AVX2'''. Which one to choose depends on your CPU installed. | ||
* '''SSE2''' -- is Intel 2001 CPU extension features many additional instructions for 64-bit and floating point operations. AMD adopted these instructions from Athlon 64 CPUs in 2003. Your CPU will surely support SSE2 and thus this dll will be your safe choice. | * '''SSE2''' -- is Intel 2001 CPU extension features many additional instructions for 64-bit and floating point operations.

* '''SSSE3''' -- is Intel 2006 revision to '''SSE3''' CPU extension supported Intel Core 2 processors and higher as well as AMD Bobcat processors and higher. '''Warning''': If you will try to use SSSE3 optimized dll on Pentium 4 CPU you will encounter a crash whenever the code reaches SSSE3 optimized part (it may not happen for some time but it will occur eventually). | * '''SSSE3''' -- is Intel 2006 revision to '''SSE3''' CPU extension supported Intel Core 2 processors and higher as well as AMD Bobcat processors and higher.

* '''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.

* '''AVX2''' -- is a CPU extension temporarily exclusive to Intel. AMD announced this extension is going to be supported in the upcoming Excavator microarchitecture scheduled for release in 2015. [http://en.wikipedia.org/wiki/Excavator_%28microarchitecture%29 External link] | |||
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.
