1. what does Poser needs more

depends, but TaskManager can tell you. Check the processes tab, it will tell you the memory usage. In the meantime I guess from your specs you're running on Win 64bit. My second guess is, that CPU is more the issue than memory because when memory is an issue, you'll definitely notice the disk swapping going on.

EDIT: I'm using a i7-990x@4Ghz. this guy has 6 cores / 12 threads instead of your 4 / 8 so the gain would be 12/8 * 4,0/3,2 = almost twice as fast. And I never had a Poser scene eating 6Gb ram by itself.

2. my system lags...

well, you don't need to upgrade for solving that, you just should run Poser in Low Priority mode. Again, go Taskmanager, right-click the Poser process, select the Priorities option and assign "lower than normal". After that, your mouse, internet video streams etc should run fine as they have a higher priority than the rendering.

There are more advanced options for handling this (structurally), I'll write an article about that. I'll let you know when it's published.

By the way: if you send your rendering to the queue manager, and set queue manager to low priority, you even can work on your next poser scene smoothly.

Usually I'm wrong. But to be effective and efficient, I don't need to be correct or accurate.
