    [FAQ]Solution to freeze and stutter using FMC

    I believe I have found a temporary fix for my stutters. As someone discovered in v10.4, setting the vsync to adaptive half refresh fixed the stutters for some of us. I don't know if it has anything to do with v10.5, but ever since I updated to 10.5 the stutters came back and worse than ever. This is a deal breaker for me and I will not fly this plane with this severe of a stutter. I apologize in advance if this is something I should not have done, but in my desire to return to flying this great aircraft I have stumbled on to what may be the key...at least for my system. I have discovered that the cockpit_reflection file could be the key. I wont say what I did unless given permission, but I made a couple of very simple changes and now the plane flies buttery smooth. The only negative effect that I have seen since making this change is that I no longer get airport, vor, waypoint displays etc on the map display. I am fine with that as I can still navigate via VOR and ILS, while enjoying the beautiful cockpit and completely smooth flight. Can someone please comment on the possibility of an update or patch that might fix this issue with a change of the reflection file that might cure the stutters with no other negative effects?

    [FAQ]Solution to freeze and stutter using FMC

    After a few months off of x-plane Ive now updated to 10.5 and wanted to get back into the 737 Classic. In the beginning I had unacceptable stutters every 2-3 seconds, but those were finally solved with the adaptive half refresh rate trick. Unfortunately the stutter now is back, but where it used to be consistently every 2-3 seconds on the ground and in the air they are now farther apart, maybe every 5-7 seconds.They are not very evident on the ground while taxing or during take off and landing, but are very evident in the air at lower altitudes. I also checked some of my other payware such as the 767 and MD80 and they still fly very smooth, no stutters. Its a beautiful aircraft that I want to be my 'go to' commercial airliner, but I'm obsessive about consistent stutters and hiccups, so with the other very good big jets available, it will go back into the hangar. Is there any more work being done to find and correct the root cause? Thanks

    [FAQ]Solution to freeze and stutter using FMC

    I tested again last night and to my amazement the stutter was completely gone, on the ground taxiing, taking off and in the air. Very strange, but I am thrilled. Maybe it had to do with making the vertical sync change two nights ago, doing the test flight then shutting down and not rebooting again until last night? I don't know for sure what has cured this, but its gone, at least to my eyes. Will hope that it continues. Not sure that I want to do anymore aircraft updates for fear of it returning?

    [FAQ]Solution to freeze and stutter using FMC

    Ok...here is an update after reading letec's post. To be fair I added a new cooling system last weekend, some overclocking changes, a disk cleanup and defrag. Since then I had not used x-plane until tonight. The only Nvidia Control Panel change I had to make was from Vertical Sync 'off' to Vertical Sync 'adaptive half refresh rate' and I now have a noticeable improvement. By the way, I found long ago that I had to use an old driver for x-plane (Im on 337.88). So, on the ground taxing, during takeoff and just after take off its still there, about every 3 seconds, but its much less abrupt and the faster I accelerate for take off the less noticeable it is. Once over 500ft altitude or so and away from the airport the stutter appears to be gone. I did not notice it again during this test flight until I landed and was turning off of the runway. It was definitely more noticeable turning the aircraft during taxi and I could count off a slight, but less abrupt hiccup every 3 seconds, but a dramatic improvement. I fly mostly from airports with freeware addon scenery, my system is an old quad, but its hot rodded, has good ram and graphics card and still gets the job done with all heavy payware aircraft in x-plane and in P3D V3.3. That being said I think the issue is still there for many if not most of us regardless of our systems, but the severity of the problem could vary system to system. If it is ultimately a coding issue I can now use the aircraft and more patiently wait for a final fix. Thanks Letec for the post. You might be on to something.

    [FAQ]Solution to freeze and stutter using FMC

    Jan Very hard to tell through video. Looks like the headshake might have been on, but I would have to say that what I saw in the video is not what I am experiencing. If you will look at the 1:34-1:35 mark you will see a more defined and abrupt stutter. Thats close to what I see every 2-4 seconds. If I had to describe it, its as if the sim literally pauses for a millisecond every few seconds. You can watch the wheel rotation from the external view stop/pause as it rolls down the runway. Thank you for making the video and your interest in this issue. Steve

    [FAQ]Solution to freeze and stutter using FMC

    I'm glad to hear its still on the radar. I must have misunderstood one of your replies to another poster that said we are pretty much not able to do anything about this. I kind of gave up at that point. Also as was just suggested I had not done a clean complete reinstall, which seems like an obvious and great idea, so i just re-downloaded the aircraft and reinstalled it. I also pulled all plugins except Gizmo from the plugin folder, but the stutter/hiccup still persists every 2-3 seconds. Some may have a periodic negligible stutter that is tolerable, but few would tolerate what I am experiencing. It destroys the immersion on the ground and at low altitude. The only way to avoid seeing it is to fly at high altitude and never look at the aircraft from an external view. Please keep looking for a solution. Thanks

    [FAQ]Solution to freeze and stutter using FMC

    Sorry to disagree...in my case the stutter every couple of seconds has nothing to do with the FMC because I haven't been using the FMC, but I tested it with no difference in the results. Also in my case the stutter has nothing to do with Windows Defender, Antivirus etc. I have tried that too. This issue is a specific conflict with this one aircraft. I just got the new PMDG DC6 and was a bit concerned about how it might perform, but it is excellent, silky smooth, no issues whatsoever. No issues with the MD80, 767 or any of the Airbus aircraft. The 737 Classic is the hanger for me too. It doesn't sound like anyone knows what is really causing this or that it is high on the priority list. If you look at the number of posts related to this issue it far outweighs posts on any other topic. Very disappointed.

    [FAQ]Solution to freeze and stutter using FMC

    Yes I do understand and see an occasional hiccup when default scenery loads when flying other aircraft. My sensitivity to stutters are pretty high as I also have a lot of experience with p3d. Once in the air and at altitude with the 737 classic the stutter every couple of seconds is not aa noticeable unless you view from outside the cockpit. The real experience/immersion killer for me is while taxiing, taking off and landing. It is bad, almost like the sim literally stops a millisecond every 2-3 seconds. I really want to enjoy this plane because it has the potential to be the very best, but I have all of the other latest excellent heavy add-ons and they all fly virtually stutter free, so that out weighs the 737 classic benefits for me. Im dissapointed, but hopeful for a solution. Keep up the good work.

    [FAQ]Solution to freeze and stutter using FMC

    Kind of quiet on this topic, but no change for me. I have updated to 1.0.4. I realize nothing was addressed regarding this issue in the updates, but Ive been hoping some of the changes might have an impact on this anomaly. Flying other aircraft until there's a fix...I hope. Could be some unexplained conflict with some of our systems as apparently not everyone is having this issue.

    [FAQ]Solution to freeze and stutter using FMC

    If the issue might be related to FMC selections this wouldn't apply to my stutter every 2-3 seconds. I know it is sacrilege, but I rarely use the FMC. I mainly fly VFR using the map display and or VOR. So, I tried a flight or two using the FMC thinking that maybe when I select EXEC before takeoff it would solve the stutter, but it had no effect. I have not tried it since the last two updates came out so I will try it again.

    [FAQ]Solution to freeze and stutter using FMC

    No change since the 1.0.3 update. I have no world traffic and only a few airport scenery addons. I uninstalled the airports, but that had no effect. My issue is still the same, exactly as another poster said...good framerates, but my stutter/pause is every 2-3 seconds and worse while on the ground taxiing and taking off.

    I made sure that the usage data box was unchecked. I still get a stutter every 2-3 seconds. Still bad enough for me that I cant enjoy flying this beautiful aircraft. Holding out for hope of a fix...

    [FAQ]Solution to freeze and stutter using FMC

    Although my system is not a powerhouse by any means...by the looks of some of the other systems that are being posted who are also having the same issue, the stutter doesn't seem to be a direct result of an inadequate system, although it could have a bearing on the severity of the issue. I have done everything recommended in the forums Ive even gone into the ACF file and tried reducing the size of the the instruments which maybe made a negligible improvement? I also was running an older Nvidia driver which seemed to work better in X-Plane, but I just updated to the latest driver, set it for performance, lowered X-Plane resolution to Low, but no luck. As mentioned, my stutter not only takes away from immersion it is down right nagging. I will watch and wait for other improvements.

    [FAQ]Solution to freeze and stutter using FMC

    Hello Just updated to 1.0.2 and really appreciate all of the fixes and efforts in making improvements. I was hoping that there might be something in the first two updates that would mysteriously cure the stutter/pause, but not yet. It starts immediately as I begin down runway. When viewing the plane from the outside as it rolls down the runway you can see the hesitation and the main gear momentarily stop spinning with every stutter. Its a nagging enough issue for me that unfortunately I will have to put her in the hangar and patiently wait for more updates and hopefully a fix.

    [FAQ]Solution to freeze and stutter using FMC

    Hi Jan I just tested your suggestions and unfortunately I still get a short stutter/pause about every 3 seconds from the time I start down the runway for takeoff and during flight. I am so hoping that this can be solved. This aircraft is just too incredible to have parked in the hangar if I don't have the juice to run it smoothly. By the way, I definitely don't have a powerhouse pc, but its been quite capable so far. Here are my specs.... XFX 780i motherboard, Intel Q9650 3ghz OC'D to 4ghz, 8gb ram, Geforce GTX 760 2gb Thanks for your efforts and responses!
