mrgeeunit, I just bought this new PC in early December. It's a Dell 8700 XP, 16 GB RAM, and an nvidia GeForce GTX 745 with 4 GB VRAM. I installed FSX Gold, and left all the settings and fsx.cfg at the default settings. The installation automatically set everything to "Ultra High", and it is working great. Even in the busiest airports (I have all the World of AI packages installed so there is a huge amount of aircraft at all the major airports) there is no lag. My old PC had Windows Vista, 4 GB RAM, and 512 MB VRAM. I was hoping FSX would perform better, but I didn't know it would work this well. If your system performs anywhere like mine, you shouldn't need to adjust anything in the cfg file. I've not had any items spawning or anything of that sort.
