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.

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

Tonga is really weak for ZEC.

why my nano can't use -i 8?

Make sure you set these env variables:

GPU_MAX_HEAP_SIZE 100
GPU_MAX_ALLOC_PERCENT 100
GPU_SINGLE_ALLOC_PERCENT 100

gunna sound noobish, but where do you set these variables? i never worked it out lol but never seemed to need too

In your start.bat file is easiest:
SETX GPU_MAX_HEAP_SIZE 100
SETX GPU_MAX_ALLOC_PERCENT 100
SETX GPU_SINGLE_ALLOC_PERCENT 100

This reply makes me curious, should the missing variables:

GPU_FORCE_64BIT_PTR 1
GPU_USE_SYNC_OBJECTS 1

that are recommended in the README!!! file still be set? I keep them just because it says so, but I have newer "higher end" cards.
