external software renderer Require CPU supporting AVX2 or SSE4.1 ?

[onelight]

unfortunately, my cpu not support AVX2 or SSE4.1
what does external software renderer useing for. Dose it is faster?

software render is accurate GE emulation. It can do all psp effects that opengl can't do , so it's more accurate but slower than opengl since it's software.

SSE and AVX speed up software render (AVX is x4 faster than sse version in most of the cases ) . I will talk to gid if we can have a SSE3 version as well , but the lower the instruction set the lower will be the expected speed

Ok, I know, Thinks for reply.

Which SSE version is supported by your CPU?

SSE, SSE2, SSE3, SSE4A

SSE4A ??? is that amd specific :~ ?

[MaXiMu]

@shadow Yes the SSE4a instruction was introduced in AMD Only.

As far as my CPU not support AVX2 or SSE4.1, I just test opengl and Internal Software reader.

just what shadow say, Software reader can do psp effects (dynamic Layer) that opengl can't do.But Software reader is slower and Low resolution.
does external software renderer is faster than Internal Software reader?
Can software renderer Rendering resolution 2XPSP like PPSSPP.

[shadow]

external software is written in c++ with asm optimizations . It should be a lot faster than the existing Internal Software render

We started using only SSE3, but at some point, we needed some SSE4.1 instructions. I have to check if a SSE3 version would be possible. At least a non-SSE version is possible, but quite slow.
