Win 8 updates X PP2014 SR3
Just a note for anyone who has updated Windows 8 within the last several days of this message. Since I updated, PP2014 has frozen many times while rendering, and the only way to get out of it is a hard reboot. Very bad situation, but I don't think it is PP2014's fault !
I checked the memory allocation and found that instead of the require 5GB+, Win8 was only allocating 2GB+. That is under the automatically-allocated option. I used the manual settings to give the system the required amount, and re-booted the machine. I am rendering faster now, and let's see if PP2014 doesn't crash.
So, for users who have updated both PP2014 and Windows 8, check the memory allocation setting.
