FSX and PCI-E bus transfer speed

Did anyone read THG's article on PCI-E bus speeds and gaming performance?Surprisingly, FSX was one of the "games" that scaled the best with increasing bus transfer speeds. It seems even with built-in mipmaps and texture compression, FSX transfers a lot of texture and geometry data over the PCI-E/AGP bus.Or, maybe the built-in mipmapping is what actually causes the sim to be bottlenecked by slow bus tranfers speeds - the engine is, after all, constantly uploading/downloading different resolution versions of the scenery textures as you fly.http://www.tomshardware.com/reviews/pci-ex...-0,1915-10.htmlThe Radeon 3850 and even the mighty Geforce 9800 GX2 are severely limited by anything lower than an X16 speed. A difference of 3.4 FPS may not seem like much, but it's roughly the difference between a 2.1 and a 2.5 GHz CPU. It's also quite possible that there's more blurries with a slower bus speed.AGP users - It's definitely time to switch to PCI-E.PCI-E users - make sure your card is using the highest transfer speed your motherboard and videocard support. Looking at those numbers, it seems even PCI-E 3.0 will benefit this sim.http://forums.avsim.net/user_files/187950.gif
