I had a question about PCIe 3.0 and the scenery complexity setting for FSX. Now some around here have stated getting better performance with PCIe 3.0 in combination with a GTX 680 card, but is that just the autogen density? Or the scenery complexity slider as well? Not sure if both sliders behave the same way.

 

Whenever I load up at KSEA my system gets hammered at extremely dense, but if I turn the scenery complexity down to normal, my FPS is great. I've noticed there's a lot of small airport vehicles, such as bag carts, luggage, and catering trucks when I turn it up to extremely dense, even though my traffic settings are off (0% on all sliders). Any performance increase with Ivy Bridge PCIe 3.0 & GTX 680 cards (or any Kepler card, such as 670) at airports such as KSEA or say KJFK using "extremely dense" scenery complexity?

 

I'm not looking at upgrading, just asking a general question.

 

Specs:

 

Intel i7 2600K @ 4.5 GHz

GTX 670 4 GB

Asus P8P67 Deluxe Rev. 3.0

16 GB DDR3 RAM

To my knowledge, the PCIe3 was shown to have no effect on FSX performance. Someone correct me if I'm wrong.

So what could improve the FPS at places like KSEA and KJFK? Is that purely a CPU issue? The models for the carts and such don't seem to have that many polygons or anything.

It is usually a CPU thing. GPU in FSX is usually connected to the amount of IQ and clouds.

Even in titles other than FSX there is practically no difference at present between pci-e 2.1 and pci-e 3.0 though in the future it may matter. Only time you will see some bottleneck is when you try to run 2 cards like 7970 on crossfire with only x8 of bandwidth available rather than full x16 bandwidth on pci-e 2.1 slot.
