I know this has been discussed before but I have a question.Recently got a new computer with two 500GB hard drives. I put FSX on the second drive (E) by itself. I noticed, however, that the FSX .CFG file installed on the primary drive ©. Is this a problem?I've read both pro and con about putting FSX on a drive other than the one with the OS.Right now my performance is nothing to brag about but then again I haven't done much tweaking. Using Vista Home Premium.This is my second post on this - can't find my original post.Jim

The fsx.cfg file should reside on your OS drive it is normal. Your OS on C: and FSX on E: by itself, you have it set up correctly.

Thanks. I kind of figured that it was ok. I'm mainly curious as to whether FSX would run better if it was on the same hard drive as the CFG file. Haven't tried to install in on the C drive to see if it makes a difference.Jim

I think that test would be a waste of time.Having FSX on it's own physical drive is so that the many scenery accesses that FSX makes as you move around in the world can be rapidly executed without interference with all the things that Windows likes to do, like paging and general housekeeping. The FSX.cfg file gets accessed once and that is it..

I think the general consensus is that FS should be on the same drive as the OS. I have just deleted my previous disk partitions to move everything to the C drive. I had to do this due to a stutter caused by slower disk access times of having FS on the partition. Search the forum and you will see many posts on this topic.Mark.

Bert has it right - FSX on it's own physical drive will be better, although the performance improvements will be minimal AND limited only to the loading of the program and flights.Mark, you have it right, but partially - If you have FSX on a PARTITION of a drive shared by the OS partition, you'll actually get slightly lower performance than if you had the simulation loaded up on one big C: drive. The partition is physically further out on the disc, and when the read/write heads need to get to the OS Partition and then the Sim Partition, they have farther to travel. From best to worst...[OS Drive] [sim Drive][OS & Sim Drive][OS Partition | Sim Partition]But in true reality, the only changes/improvements you will likely see are in loading... in game FPS will be unchanged. -Greg
