The effective hashrate of recent JCE is back to >98%, close to 99% efficiency, as before. And as all current versions of miners so far (xmrig, srb, teamred...).

I'm polishing my fix of the regression on CN-Fast on Vega. Looks like my auto-hybrid introduced in the experimental -x, -y, -z and -sync versions works bad in such case, so i introduced an override --legacy to force the good old non-hybrid mode.
I benched it to be either a little faster or slower than b12 depending on the cards and algo, hard to tell if it was an improvment or not. This way i'll let the user choose.

edit:
@cryptoprofitswitcher: online is the b13, partial release with just the .exe Inside
you may try with undocumented parameter --legacy to check if it restores the speed on your dual Vega.

@other: it contains a very small optim for Vega, and for non-heavy algos, if you want to take a look.
the --legacy may also give a few extra perf, but it's ignored for heavy-class algos, it's just for CN and CN-Light

if it solves the problem, i'll make it a full documented release.

Are you sure hybrid is not affecting heavy algos? If i run 32q heavy on my 8 polaris rig, I can run my ryzen 1600 @ ~525H/s (cnv2). If I run any 33 heavy, I can only get ~400H/s on the cpu while GPUs are mining. Given that 33b13 gives me an extra ~100H/s per GPU vs 32q, I'll take the tradeoff if it's necessary, but just checking that something hasn't been overlooked.

EDIT: --legacy doesn't help, but still just want to make sure something hasn't been inadvertently changed.
