To all: you can see low speed at highest possible "-i" value, if so, reduce it. For example, you specify "-i 8" for 280X 3GB card, miner reduces it to "-i 7" automatically (shows "not enough GPU memory" message), but it may work much slower than "-i 6".
So if you see that new version is slower than old version - try to reduce "-i" value a bit.
In some cases you can increase "-i" value, for example, in my tests Nano cards work best with v12.2 using "-i 7", but for v12.3 "-i 8" is faster.
Tonga is really weak for ZEC.

@Claymore Can you make something to improve 380 series? Currently I have 210H. Too low... Thank you in advance

why my nano can't use -i 8?

Also, why do the compute units differ between your cards?
ZEC: GPU0 455.346 H/s, GPU1 481.857 H/s, GPU2 460.153 H/s
v12.3 -i 7
gpu0 is fury
gpu1 is fury x
gpu2 is nano
for v12.2 can't use -i 7 , for v.12.3 i can use -i 7 but can't -i 8
I think that's pretty normal, my Fury default to i6 and I see the same ballpark speed. Honestly doesn't even change if I force it to i5 or i4
That is right. My R9 Nano run better on -i 7 in 12.3 and -i 6 in 12.2.
