When users blame PM 3.0c being unstable, I believe it's their settings eg overclocking too much, not enough swap file, maxed out psu power, not having proper ventilation or using older driver version could be the issue.
Of course PM is not 100% perfect but if a lot of users doesn't have problems, please relook at your software and hardware setup.
For a while I cursed at PM becoz 3 gpus had errors only to discover that increasing my swap file solved it. Another problem 4 gpus having lower hashrate due to thermal throttling. Replacing stock cooler with aftermarket one max out hashrate.
Now running 9 GPU @280mhs, 7 RX580, 2 GTX 1070 in one rig.
Believe me, I understand where you coming from. Most users want "set it and forget it" software, but it's not that easy in this business. Besides, asking questions is easy than troubleshooting.
People who discovered PM recently don't want to go through 100+ pages of reading.
I was lucky to find PM in early January and been using/following since. I don't post much but also don't have any questions. Devs seem super responsive as well.
