Hi,

I just released an optimized version of sgminer for jackpotcoin for 14.6 amd drivers.

It was tested on my R9-290x at 1050MHz.

The hashrate is 5.97MHash/s
with the standard jackpotcoin miner, the speed was 3.5MHash/s on 13.12 drivers and 4.1MHash.s on 14.6.

So it is an increase between 50% and 100% depending on the drivers you currently use.

This is still lower than nvidia hashrate (however here it is running on all the hashes... so this is at that level still a work in progress

The source can be found here: https://github.com/djm34/sgminer-jpc
windows binaries here: https://mega.co.nz/#!0d9xjagT!H-K3q-XcyHIGEPcPQOKPcW7sdvh8cAaAmHqNRP09zBg

To use the algo: sgminer --kernel jpc -o pool -u password
