I haven't done a comprehensive comparison to the differences. But initially there is a fundamental difference with AC13 and AC12 in the ability to handle complex buildings and information on the fly. Calculations, rendering, schedules, 3d, 3d-documenta all seem to tremendously affected. I would almost venture to say that it's 8-16 times faster but this is a guess (+/-10% based on 2400min(ac12)/240min(ac12)). That number might be based on the polygons of the model I was testing (highly complex). Yet I was able to do a 999dpi 7inx8in sketch rendering in roughly 4 min as compared to 40 min on the same system (single processor AMD, 2gb RAM). I like to start my comparison on cpu's ([GS] recommended min.) that you can see the difference rather quickly than a quad or something with more under the hood. <BR /> <BR /> I would be interested to hear everyone's else's experience with 64bit AC13.</T></DIV> Mon, 05 Oct 2009 18:00:17 GMT ares997 2009-10-05T18:00:17Z https://community.graphisoft.com/t5/Modeling/64-bit-Archicad-13/m-p/200774#M108758 <DIV class="actalk-migrated-content"><T>The 64 bit version of Archicad 13 is really fast.
