On my previous install of FSX I used mainly the Bojote tweak. It worked OK and I got better FPS with it. Then somewhere along the way my FSX started to show weird graphics errors so I decided to uninstall-install everything back. Only this time around I went with Nick's guide. First optimized my Win7 and then installed FSX. I read all the things Nick had written in his guide concerning the different fsx.cfg tweaks and the "if it works, don't try to fix it"-principle. I applied just the affinitymask, TBM, reject threshold and highmemfix (+forcefullscreenvsync=1) tweaks and disregarded the "small part reject radius" and "fiber time fraction" tweaks, which Bojote's tool added to the .cfg. Then I took off from KSEA and was amazed by the smoothness I was seeing. Of course there was one more thing to be fixed... the clouds were disappearing/appearing as I panned the view back and forth. I was getting fairly frustrated because I remembered seeing a topic somewhere which described a fix for the problem, but couldn't find it. Finally I found it and the flickering cloud problem disappeared. To sum it up: The different tweaks really do work and you really should use them. But only if you know what you're doing because adding something (or a wrong value) to the .cfg can cause instability and errors.

It might be that I'm simply going insane and remembering things that aren't really there... ...but I swear I saw a topic or a post that went something like "how to prevent cloud popups"Anyone know where that topic/post might be? I'm very interested in finding it since I seem to be having these appearing/disappearing clouds from time to time. By the way, what's the downside of running FPS unlimited and not using a FPS limiter? (I just ran some tests and man it was smooth with unlimited) I'm using VSync so it shouldn't go past 60 FPS anyway (or at least the picture I'm seeing from my monitor since it's 60Hz) EDIT:I found it AND it worked!http://www.simforums.com/forums/how-to-get-rid-of-annoying-flashing-clouds_topic24830.html

Since the "textures loading slowly in outer views" problem is very much FSX related I figured I'd post this. So if anyone is having the same kind of problem I do have a solution! (And thanks to Terrence and McPhat's superb customer support!)

OK, after a rather lengthy defrag process (man O&O does take it's time on a 700+Gb HD!) I finally got FSX installed and tweaked. At the moment I don't feel like going to the PMDG 737 NGX, the whole uninstall-install process was way too much work. I'm going to get everything else sorted out first. Like for instance steady FPS and no texture flickering, etc. -> Haven't tested the differences between external and internal frame limiter. I previously found that the internal limiter causes stutters, but that was on my previous PC.

I have to disagree with you. FSX was released in October, 2006. That was the time of Intel's Core 2 Duos and Nvidia GeForce 7900s. Now people have a whole lot more power in their PC's and still we have to think about performance issues. Just think about other more modern flight simulators, for example the DCS: A-10C, which looks gorgeous AND runs way better than FSX. Thanks for the tip though, I'll try the TEXTURE_BANDWIDTH_MULT= tweak when I can.

Last night I was thinking that OK maybe I don't need to fly the 737 at the moment (maybe it's loaded with bugs and/or PMDG will optimize it a little further and then I'll be able to fly it better)... but then I noticed that different graphics started to flicker or blink or some other word (sorry, English is not my main language), like the terrain flashed really quickly with something other than the land texture. And I started thinking, OK I'm probably not going to fix it simply by reverting to a default fsx.cfg because I've also been changing the textures with REX a lot, adding addon planes, addon sceneries, etc. So I decided to start from scratch. Uninstall everything, defrag properly, install everything back (in an orderly fashion and not all at once), defrag again, and go on from there. Thanks for your answers by the way. I think you're very correct in what you say. Just because I can run Witcher 2 or Deus Ex Human Revolution maxed out with my PC, it doesn't mean that I can do the same with FSX. Which means only one thing, FSX's coding is really horrible. But that's just the reality I have to live with. After I've finished the rebuilding process I'll try your settings Rockliffe and report back with results. Oh, none of you said anything about the slow texture loading... is that something that can be fixed with a setting in fsx.cfg? (It's clearly related to heavy textures, like PMDG's 737 VC or McPhat's HD livery on the MD-11)

Hello all, (first post and all...) My problem is this: I have a fairly high endish computer but I cannot seem to make FSX run as smoothly as I would like.(AMD X6 1100T, GTX 570, 4Gb DDR3, Win7 x64) (addons: REX, ASE) I have read Nick N's guides, I am familiar with Bojote's tweaking tool, I am using the recommended nHancer settings... all in all, I know quite a lot about tweaking when it comes to FSX. But I'm sure that I don't know everything and even possibly have tweaked it a step too far (hence the "not running as smoothly...) With default planes I have no problems whatsoever. Even with REX's (+ overdrive) 4096 hi-res clouds and sparkling wave animation, FSX runs very smoothly (oh yeah, I forgot to mention that I use FPS limiter 0.2 with 30 FPS lock, FSX's own set to unlimited). But the problems start to arise with PMDG's planes. First I bought the MD-11 (what a fantastic aircraft that big thing is!), got nice FPS in VC. Then I got McPhat's HD liveries for the MD-11 and the problems started. Now whenever I use one of those HD liveries and transition to an outside view, the plane is all white (without textures) for about 3-4 seconds (and there's no sound either while white) and only then do the textures load. Oh, and they load in increments, not like all at a time. That's a major bummer because I like to use the outside views a lot while flying (yeah, that's why I got the paints...obviously). Is there any easy way to fix this? I do not have an SSD and buying one at the time is kind of out of the question. (I have read that slowly loading textures are cured with fast SSD disks) Second problem is with my other PMDG plane, the 737 NGX. (I didn't post this topic to the PMDG board because the problem is not with the planes, they work just fine.) I get really bad FPS with that plane. When I load up a flight and I'm on the runway before taking off, the FPS jumps from 12-24, constantly. (Without the limiter it's somewhere in the 23's, 24's but not higher.) And it definitely isn't smooth anymore, it's clearly stuttering and isn't fun to fly anymore. What do you suggest I must do to make the 737 run smoother?I'd hate to stop using ASE and/or REX since they're such great addons.
