StakXMR Cryptonight v8 performance

[Ursul0]

Hey guys, how's your v8 performance?

On Polarises (both 8GB and 4GB) I see a drop in hashrate of roughly 10%

However Vegas is a diffident story, it seems to be somewhat inconsistent.
My optimal v7 threads intensities were 2024 and 1968 and while it seems to be working fine on a single Vega56(18.6.1 driver), producing about 20% lower hash, just above 1600...
It gives me trouble on a rig of mixed ones (FE, 64, 56) it will still run on those high intensities, but the GPUs would produce around 1000h/s
And after I lower it all to about 1800&1200 some of the GPUs(one 56 and one 64) would not go above 1000h/s, while the rest would hash  at around 1300.

Any ideas?

Just built 2.5.1, yet it seems to make no difference.

Not sure if this is a related issue, but I'm getting a similar issue (one 64 and one 56 in a rig will not go above a few hundred h/s). Tried all the usual things, kinda stumped now. Running Cast.

I have the R9 nano, dropped from 710H/s to 540 H/s using the same clock. The V7 uses Claymore and V8 uses XMR Stak.

I could never get my older r9 cards to perform on other miner like they would on claymore he's working on the v8 so hopefully will be out soon

xmr-stak won't work on my R9 Furies, but xmrig did, I got 840kH\s@130Wt per card using 1920 intensity(tried 2024, 1984, 1952 but it didn't work).

ps all my furies have 60CU(50% unlock)
