I think I've discovered the reason why Phoenix Rising has started to put out such low hashrates compared to before. Checking the PR.log file the default argument is now missing the VECTOR flag.
Manually adding VECTOR into the "other flag" field brought hashrate back up to its original levels. If you could have it automatically add that flag in the next version that'd be great. Or a check box?
I think he actually told about it a couple of times

Checkbox's good. Autovectors - not good, I think, because I would want to set all flags by myself.
