New machine - FSX is still jerky

I just put together a new machine consisting of Asus P6T Deluxe 2 mobo, i7 940 cpu, 12 GB corsair ddr3 ram, Windows xp pro x64, EVGA GTX 285 graphics, Corsair 850 watt PSU. I figured that I should have no more stuttering problems. If I set the target frame rate to 50 it will run in the 40s and up to 50 most of the time. But then it starts dropping down to 6 or 7 then back up to 50 and stutters. This happens most in traffic areas and near the ground. I have reduced the graphics options in steps trying to get it smooth. It doesn't make much difference from maxed out down to about medium on everything. Today I updated my graphics driver to the 64 bit version and there was no change. I have not tried to overclock any of my parts yet. I didn't really think it would be necessary. FSX was running nearly as good with my old system which was pentium 4 3.0 Ghz, ATI Radeon 9800 pro, 2 GB ram. Anyone have any ideas what I need to adjust? :confused:

I have almost the exact system but an i7 920, OC to 3.7 Ghz only 3GB RAM though. I had to put my texture bandwith multiplier or whatever it's called in the FSX.cfg file to 10 instead of the stated 40, that took away my stutters for some strange reason.
 
I seem to recall Phil Taylor saying that for some reason lower texture bandwidth multipliers work better in FSX than higher ones. That's exactly the opposite of how it worked in FS9. Either that, or I'm hallucinating again.
 
Thanks for your reply. I will look into that when I get back home. What made you try that? Are you able to run FSX at max graphics?

It was just a trial and error thing, I had tried higher numbers with worse effects each time so I just tried the opposite, don't know why but it works for me.
 
as strange as it sounds, try flying with the tool bar open (that blue bar on top) hit ALT, fly with it, and your stutters shall disapear!
 
Interesting

Hey Diego,

That sounds interesting indeed! Would you care to elaborate on this please? Is it because in windowed mode, less resources are used or something like it?

Did you flash your new Mobo? the one that comes on it is pure CaCa...

I just changed mine from 80 to 40 and then again to 10. I flew over some of the more complex urban areas in my F16 and I could swear it's a smoother experience.
I need to check that again ...........
 
I got 12 GB because it was only $200 and because the mobo would take it. In the future I will probably need it.
 
I got it at newegg. It was actually $208 and there was a$10 rebate. I was going to get a combo but it was actually about $25 more than buying them separately. I was asking a question on the forum and someone tipped me off on it.

Decent system, but WHY 12gb of ram? OVERKILL lol

6GB is even overkill but thats a popular choice over 3

Apple computers, their huge tower systems, are now setup for 32Gigs of Ram. If I could, I would have 12 to 32 Gigs of Ram, but Windows 32Bit cannot handle that. Imagine the massive power of 12 Gigs!!!! Man.. It would be amazing in gaming...
