There were a lot of ICC optimized builds before. Why not now? No need?

As title. Just curious to check only. Was compiling into SSE/AVX/OpenMP version provide any performance advantage? Seems no more person doing so since v4.0.x

Just checking. Many thanks!

Nobody could ever show a performance increase. I tried to benchmark that a year ago and averaged around -0.5% FPS with ICC builds, which is insignificant and probably due to interferences more than real differences.

It is a major pain to configure and fix the errors to get it to compile whenever a main source change breaks the icc compiling. All that work isnt worth the very minor speed increase. I am not surprise the people who were offering icc builds decided to just quit doin it.

yup, one of the reasons. another one is that dolphin is pretty much fast now.
Ive compiled some time ago, and couldnt see any difference between it and official build (all games i own worked on 60/30 - max fps / with limiter of course). Didnt want to bother to try without it.

Mr Delroth here and of course all members of Dolphin team did very good job.

I would like to see at least a few revisions Dolphin 4.0 AMD Optimized / SSE3 ICC

So I have AMD CPU well AMD very terrible performance for a Dolphin. A new compiled mainly under Intel...

I compared the optimized builds and they really work faster, in particular, missing small "sifting" FPS.

On older computers (CPUs) increase in productivity is particularly noticeable and it can not but rejoice

Older builds are unsupported. How does it compare to the latest dev builds: https://dolphin-emu.org/download/ (4.0-5186 as of writing)

There's very little purpose in a build optimized for a particular platform because practically all of Dolphin's time is spent in runtime-generated code (or in video drivers), which isn't affected by the compiler.

If you want to try to optimize the generated assembly for a particular CPU, you'd need to do that in the JIT, not in the compiler.

It also broke the GUI several times resulting in being able to only open Dolphin once and never again.
