per-GPU (r9 290) performance:
scrypt: 840 Kh/s
scrypt-N: 420 Kh/s
x11: 3.35 Mh/s
x13: 2.55 Mh/s
keccak: 420 Mh/s
BTW: as far as I understand better x11 and x13 performance can be achieved with 14.6 drivers? Or are there any other hacks needed?
The STILT's BIOS (see litecoin talk forums - Post 1 + Post 1) is definitely worthwhile for 290s. And I have seen a large boost with 14.6 for x11/x13. Worksize and intensity are also VERY important. You will see huge variance based on your worksize and intensity settings. + or - 1 or 2 on my xI values and I see a 1MH/s drop in hash production. Up or down one worksize unit, and same thing.5x R9 290

(Overclocking the engine results in higher hashrates, but the marginal gains don't seem worthwhile). The only difference with the higher hashrate card (#0) is that it has the best airflow and is consistently cooler - it actually ran at 4.44MH/s for several hours before jumping up randomly.{

Hot switching between X11 and X13 works quite well. I got X11, X13, and Nscrypt switching working okay (slightly decreased X11 hashrate), but adding more algorithms hits occasional stability issues - still tuning/testing. Basically, the more algorithms I try to hot swap to, the more hashrate seems to deteriorate.
