Some users have recently had their accounts hijacked. It seems that the now defunct EVGA forums might have compromised your password there and seems many are using the same PW here. We would suggest you UPDATE YOUR PASSWORD and TURN ON 2FA for your account here to further secure it. None of the compromised accounts had 2FA turned on.
Once you have enabled 2FA, your account will be updated soon to show a badge, letting other members know that you use 2FA to protect your account. This should be beneficial for everyone that uses FSFT.
affinity doesn't really matter with F@H... I'm pretty sure that it's been shown there was little to no gain in setting affinity on dual processor boxen... But what poddo said is correct, if you run more than once instance, you need to set the machine IDs (1-8) accordingly....
The important thing is for more than one console, you need unique ID's, F@H figures out how to use all the CPU power out on its own. There is no need to worry about affinity.
