The Death of OpenMP - Kurausukun - 11-07-2014
So the OpenMP texture decoder was removed as of a few builds ago. This made me slightly worried, as I always have the option checked. I have, however, never explicitly tested whether it provides a noticeable speedup. Are there any statistics on how big (or small) of a speedup the option actually gave on the latest builds, or did it actually offer pretty much no speedup at all?

It offered no speedup at all and it actually makes new mario bros wii run in slow motion.

About time this happened. Some people used to note that OpenMP reduced "stuttering" in games, but as of late no one's been claiming that.

OpenMP is outright dangerous in Dolphin. It can cause extra crashes in dualcore due to how Dolphin's dualcore mode works.

I actually noticed an improvement on project m once openmp was taken out (never tried games without it) Much more smooth gameplay on my end. [:

And THAT is the best example for why it needed to be removed that anyone could ever hope for.

Thanks for the replies, that's very reassuring. I hadn't noticed any real difference myself, but I wanted to confer with others.

In Project M it offers a bit of a speedup, stuttering occurs less often. So yeah. I leave it on for that reason alone.

It's all a placebo.

Eh... I did 2 benchmarks all on the same five stages, it produced a noticeable difference. Mainly at the start of each round and during respawns/deaths.
