All those projects are windows only (lol).
All those projects are already bypassed by several
organisations.
If PB support drops, open the window and jump !
Like i already said, will you trust a company that is paid by gaming industry and have employees working for anticheat purpose or will you trust a cheat coder who was still selling sources like 6 months ago after droping the ETAC project ?
UAC would be a good choice or even AEQUITAS, but again comes the multi OS support ...
But if TCE dont use a modified ET i dont see why PB would drop the support, streaming being the best way to get a proactive protection.
