What Hardware Does What? - Upgrading your Hardware for Vectorworks in FAQs Posted March 27 1 minute ago, DanJansenson said: Jim, If the chokepoint in my setup right now is Hidden Line Render, then a big investment in a faster CPU(with more cores) would be better than a big investment in a better GPU, am I reading this correctly? It depends, if it's Hidden Line and not any kind of sectioning, then normally CPU cores is the most important. But if its hidden line thats being delayed by the single core geometry or sectioning phase, then the core speed would be most important. You can check this by looking at Activity Monitor and seeing if your machines cores are all active in the CPU section while youre waiting or if it seems to be jumping from core to core.
