I have a new computer with an AMD Athlon™ II X4 620 Processor 2.60 GHz and 3GB Ram but I can only use GSdx (MSVC 15.00, SSE2) 0.1.14, is there any other graphics driver (other than the ZeroGS) that I can use since my cpu is not compatable with SSE3 or SSE41?
you can always try zzogl
but gsdx will be better anyways, even the SSE2 version
nope gsdx sse2 your only option. but don't worry there's no big differance between gsdx versions as far as i know.
There's like a 1-2fps gain from sse4.1 to sse2 from my experience, though it doesn't help knowing the improvement if you can't use sse4.1
