Weird, my fastest worker (3 GTX 780Ti ~ 540 MHash) gets just 80% accepted shares on max.netcodepool.org, but the other workers (300 MHash and 178 MHash) get 96% and 98% accepted. Unusual.
Christian.
Yeah, my two gtx 780's are at 80% accepted as well.
Instances or workers? I can try different workers. They are running in two separate instances right now, pointed to the same worker.
