I posted about this before but did not get a definitive response on the forums. What is the official word on multi-processor support when using a system with hyperthreading? In my situation not all of my CPU's (virtual/hyperthreaded) are being seen by After Effects.
That sucks, but I honestly have no idea. Could you download a tool like CPU-Z and verify? I can only imagine some specific BIOS configuration - or once again a missing motherboard driver or system DLL - doing something weird and preventing all cores from being seen. Otehr than that we probably can once more discuss AE's creepy MP and memory logic until we rot, but that obviously doesn't help, either...
Mylenium, thank you for taking the time to respond. I will check out the cpu tool you mentioned but I don't think I'm missing any motherboard drivers... possibly a system dll maybe though... however if that's the case I don't think any application would be capable of seeing all of my proc's.
