ArchiCAD 13 slower on new i7 vs core 2 duo laptop?
Hello, I recently upgraded my macbook pro from a 2.5ghz core2duo to the new macbook pro 2.66 i7 and i find that my old laptop was faster in computing the 3d conversions (steps 1-8 to generate the 3d window). it is a very marked difference (1-2 minutes longer than the old machine). I re-installed to no-avail. does AC 13 have issues with the new i7 hyper-threading? any setting i might be missing? anyone else experience this? thanks!
FIXED. You have to turn off the video card automatic switching in the system prefs. it is wicked fast now. what took a minute on my old machine is near instantaneous.

it has dual video cards:
internal intel 288mb vram
NVIDIA Geforce GT 330M 512mb vram
the building of the 3d window is slow (steps 1-8) but once it is built it is way faster than my old machine.
might have spoke too soon. there is an improvement but the re-build still takes longer... i remember AC13 using both CPU threads to process the elements, on my i7 only one thread (of four) is being used.
