I think GTX580 is going to help yes, but I really can't say for sure. There are very little people who really compared both cards well, to say there really is a definitive difference. I know only mine does a good job and I have good FSX, as good as it can be...You can't compare FSX to other games - doing that is going to drive you crazy.I think your RAM is quite slow. But according to some posts, it shouldn't be a bottleneck. Some said that 1600/CL7 was the best combo for FSX, and that it was the smoothest experience. Now you can argue if placebo or not...My best advice is (not that you have to do it now) is when installing do correct installs (one of my favorite ones is a correct chipset driver installation, which should be forced by -overall tag for instance), keep the computer extremely clean and without any AV or so, or at least disabled when FSX runs.If Asus is so bad, I don't know - can you show me some proof of that? I have never heard of a mobo causing stutters... I have Asus and have very little stutters (but yes, I do have them even with the monster-system of mine).I have to say though, really high settings, though NO AI, and AG also not maxed.

Word Not Allowed, and the others. Right under this post is a video example. Well, you might say, Arjen, c'mon, this is silky smooth! So it turns out I'm just being too perceptive. OR - you guys might say that this is simply low framerate. Let me tell you, that's indeed what it looks like, but the framerate was around 40 right here all the time! Problem is, there are a lot of little tiny lags and stutters, with sometimes a bigger lag in it. I've seen worse than here in the video.@Word Not Allowed, about the RAM. I always thought that CL9 was faster than CL7, so that's why I chose that. Or am I entirely wrong here? What would you recommend, 2133/CL9, or 1600/CL7?http://www.youtube.com/watch?v=XsDo7dq0xsw&feature=youtu.be

OK, hate to burst your bubble, but FSX is never going to get MUCH better. Maybe a little better if you replace the GPU to GTX580 and faster RAM. But what you are showing is going to be there, in a similar effect.If you want, we can do a test-compare.I have a takeoff sequence in KSEA which I could send you. Testing is without ORBX.LOL no, lower CL, faster the RAM. CL7 is faster than CL9. Either 2133/CL9 or 1600/CL7. There were comparisons here, resulting in little better frames with faster RAM. Just do a search, not that hard to find. Courtesy of Dario.And btw. this effect has been there since FS9 as I know it, and it has always been connected to frames. If you limit FS9 to 30fps, you would be looking at similar video. Achieve 60fps with FSX, and you'll get rid of these stutters.

So I made one for you to calm you down. Sorry about the bad picture quality, it was under the bad angle to my TN panel. But you can clearly see the stutters.

LOL no, lower CL, faster the RAM. CL7 is faster than CL9. Either 2133/CL9 or 1600/CL7.

Well, the CL number is the number of memory frequency cycles we have to wait. Lower CL value at the same memory frequency is always faster.CL9 @ 2133mhz gives a latency of 8,44 nano seconds. CL7 @ 1600mhz gives a latency of 8,75 nano seconds. So CL9 @ higher frequency can give a lower latency than CL7 @ lower frequency. But please dont stare yourself blind on the CL number. It's the memory latency AND speed that will give the actual benefit. So at the two examples above 2133/CL9 is clearly better with 0,31 nano seconds lower latency and 33% higher speed compared to 1600/CL7. Effect in FSX? I'd say around 2% higher FPS at times when we are CPU limited. That is one extra FPS @ 50FPS. Effects on the stutters you show? I'd say none.

I believe that the only way to have a totally fluid Sim-experience is to use X-Plane or Aerofly FS instead!Arjenfsx, here´s some RAM suggestions:http://www.newegg.com/Product/ProductList.aspx?Submit=ENE&N=100007611%20600006050%20600006069%20600006127%20600006156&IsNodeId=1&name=7@SAAB340:Good info, thanks, but arjenfsx has "1600 CL 9" not 2133 Mhz...

Word Not Allowed, what you see right there, is exactly the same thing I have all the time. Continuously short, small lags and stutters. So this means pretty much everyone is seeing this? I'm just being too perceptive. Do you think that 1600/CL7 RAM will reduce those little lags?

Unfortunately I don't live the US, so we have no Newegg here. :) Just looked up most of those RAMs, and they almost all out of stock. The only one that is good that i could find, was G.Skill Ripjaws 2133 CL9 kit, which gives, a slightly lower latency compared to 1600/CL7, as Saab said. And it costs only 70 euros. Tor, after just having seen Word Not Allowed's video, I feel a lot more relieved that it's not my hardware, or user error. Those little lags are just always there (especially in heavy sceneries). However, strange thing is, I've never really seen them with my older videocard, I got lower fps instead. Probably because the newer the hardware is getting, the more problems FSX is gonna have with it. It's just getting too old. One more reason why I'm looking forward so much to PMDG switching to XPlane 10, let's hope we will all switchover soon (in around 2 years, lol).

Well, look at it like this: Since I have FS9 I can remember having this. And it was on every hardware, GPU or CPU or RAM... and it was the same effect.As I said in my previous post, if I achieve 60fps, then I don't see them. In FS9 I was able. In FSX if I strip it down.As hard as it sounds - you will have to live with it.No, I don't think other RAM is going to much help it. Maybe a little, if even that much. Also SAAB said the same thing. I share his opinion.

Man, nothing to do with FSX itself. It was same in FS9. It's the engine. It didn't change much, and I don't know how it was before FS9, since with +/- FS9 my official simulation began...And with lower videocards, you got stuttery experience because of the lower FPS. Lower FPS are the same as stutters, but more continuous.Achieve 60fps stable in that turn and you'll be looking at the smooth ride.

@arjenfsx:Yes, get the GSkill Ripjaws, apparently there's min. diff. when you run it at 2133..I agree about FSX.3 years ago I discovered FSX, installed it on a HP Pavilion with an AMD 2,3 Ghz Quad CPU, a Nvidia 9500 GT card, some ordinary DDR2 Ram, and I was impressed and blown away by the performance!Why?Because I set the sliders so it was playable, simple as that.. ^_^It's human to seek perfection and get that little bit more "awesomeness", so the past 3 years have been a hardware purchasing and tweaking adventure - with a bit flying - and I´m now kinda settled with this i5 2500K rig.Is it fluid and perfect?No, FSX will never be smooth like all the new FPS, Racing games...

Yes, you guys are all right. FSX is never gonna be entirely smooth unless you get no lower than 60 fps. Fact is, you guys learned to live with it. That's what I'm gonna do now too. I hope I can enjoy FSX for a long time now, with some new promising looking add-ons (PMDG DC-6, PMDG 777, yes I know a lot of PMDG, lol ) coming shortly. I just hope that my GTX 580 is gonna increase my experience just a little more. After this, I just should fly. Instead of tweaking whole days, and only making myself more upset knowing that it's not gonna work anyway.

One question though... What's the best way to reduce those stutters as much as possible? Like some specific fsx.CFG tweaks. I've already a tweaked FSX.cfg by Bojote's tweaking tool. But perhaps there are ways to reduce this even more?

I like Bojote's tool for what it does, but I don't like what it's doing on my computer. I understand most of the tweaks there and what they do, and I tested them extensively.What I suggest you do:Download the file I attached, rename it to rar and unrar it. Load this situation. Just pull the brake and keep it as it is. It's gonna go straight, don't worry. Observe.Use this situation to make compares between tweaks.The fact is: each computer behaves differently, and I get the best performance with my current configuration. Even driver change can mess it up (yes, tried new betas). It's very easy to see in this situation how your stutters perform.

Sorry Word Not Allowed, could you please give more detailed instructions? Load this situation where and how? What is this file exactly and how do I run it? Is it some kind of video?

Arjen,I'm very happy to know that you have found the answers you sought. I honestly thought that you were having "real" stutters or lags. The video illustrates, as others have pointed out, is just FSX being FSX.If you can live with reboots, then stick with what you have until the next generation of HW or when XPX matures. Congrats!
