And now, how about collecting a good hefty bounty for a working effective GPU miner? I'd put down up to 1000 DRK - not much but if many people donate it'll build up.
If more people are interested I could work on GPU miner for a bounty. I already have something more or less working (pools are accepting shares, also solo-mined one block this night with it), but it's still very slow (nearly 2 MH/s on Radeon R9 290). Unfortunately I can't promise it will get much faster, still working on possible optimizations.
I'd been in to donating for that for sure. Have been wondering why that hasn't happened yet. I'll check back in a bit and see what you thinking for a bounty.
