Seems to be a lot better than running under wine, at least the 64bit version. I only have access to a 32bit virtual machine atm that i compiled it on, and it didn't seem to perform very well, but try it out and let us know how it does. It's still rough. Keyboard input is weird. Have to type a letter and hit enter, and some don't map the same as the wine version. he'll be working on it tomorrow i think.
What is the difference between this and 'jhPrimeMiner_RdBBeta3'?
