Setting up Windows version: Difference between revisions

The default PCSX2 installation has GSdx in 5 versions: SSE2, SSSE3, SSE4.1, AVX and AVX2. They are in fact the same plugin compiled using different optimization instruction sets.

<br />Use only the appropriate version for your CPU otherwise the emulator may crash. Also note that the difference between the versions speed-wise is in fact minuscule and only some games are showing any improvements in speed when using more optimized version. So if you are unsure, your safe choice is the SSE2 version. Here's the order from the slowest to the fastest one for reference:

The new AVX and AVX2 instructions give a minor speed up '''only in the software mode of GSdx''' and do not improve the hardware mode.

<br />Note to AMD users do '''NOT''' mistake SSE3 with SSSE3 (1 extra S) and SSE4A with SSE4.1, they are totally different and are '''NOT''' supported on AMD systems before Bulldozer/Bobcat. Please fall back to SSE2 plugin instead in case your system has older CPU.
