FFTF set to 0.33 is not needed with limited fps, since this is default value. With unlimited, i have no a idea if this, CFG entry, is taken in account by P3D engine(default is 0.01 with unlimited) - i can only tell you that it's not considered in P3D "max allowed amount of textures per frame formula". To elaborate on this: With limited FPS, MAX_TEXTURE_DATA = (TEXTURE_MAX_LOAD * (TextureMaxLoad * TEXTURE_BANDWIDTH_MULTIPLIER)) / UPPER_FRAMERATE_LIMIT with unlimited FPS, MAX_TEXTURE_DATA = TextureMaxLoad * TEXTURE_MAX_LOAD The result, MAX_TEXTURE_DATA, is the maximum number of bytes to load per frame. I belive this is why LM recommends tweaking "TextureMaxLoad" only for better texture loading(and not TEXTURE_BANDWIDTH_MULTIPLIER), becouse TBM is ignored with unlimited FPS, and TML works with both settings. This is how it worked in all MSFS based simulators. But like i said, we can only speculate on this, since we don't know if LM changed some other things internally. I doubt it, after i did a lot of testing. The idea is to somehow limit your fps and don't waste CPU cycles with unlimited FPS, since this will allow better scenery loading. Until now, the best solution seems to be monitor capable to run at 30Hz, unlimited FPS in P3D with vsync + triple buffering. I didn't have a chance to test this, but my alternative is to limit FPS internally to 30 and set FFTF to 0.01. I use this for PMDG and FSL, not needed for Maddog(for example)on my system. I also belive my P3D runs best with default settings, but i use this becouse i get 20FPS with PMDG 747 with default settings, and 30(limited to 30 in both scenarios)with above settings applied. I can observe some blurries which are not there with default settings, but it's not so bad and i'm ok with that compromise. I can also move more sliders to the right this way

It deppends on other settings too. For example, on my system, i get blurries if i use affinity mask to offload one core. It worked great with FSX, but not with P3D. We can only speculate, but i belive this is becouse P3D has a much more data(and especially textures)to load per frame then FSX, and we need more computing power. Do you have any cfg settings, tweaks apllied? FSX loads more textures with limited vs unlimited FPS, this is probably why blurries disappear with limited FPS. In P3Dv4 this is really equilibrated(the texture loading limit / max allowed textures per frame). There should not be a difference i how much textures can be loaded(with default CFG, no tweaks). The only difference i am aware of is the FIBER_FRAME_TIME_FRACTION, which is much lower with unlimited FPS. This means less CPU time per frame for texture loading, so i don't understand how you can get less blurries with unlimited FPS. This is not my experience, and i tested it a lot. This is why i asked if you have some other tweaks applied, some of the CFG settings are ignored with unlimited FPS

The thing is, FIBER_FRAME_TIME_FRACTION defaults to 0.33, but only when using internal FPS limiter. If you set target FPS to unlimited(internally), it defaults to 0.01. So, it is a less CPU time dedicated for texture loading(and consequently for scenery rendering). This is why many complained about blurries with unlimited FPS, especially in FSX days. Basically, with limited FPS, in P3D(and other MSFS based sims), focus is more on texture loading. With unlimited, focus is on the performance. But you may get stutters due to FPS variations. There are some other things, like - the texture loading formula is changed internally(limited vs unlimited FPS), this is why changing some CFG settings may work or not, based on your choice of target FPS - some are ignored with unlimited FPS for example. But in general, internal FPS limiter should work better, i just explained why this is not the case with P3D. There may be a workaround. Becouse I don't have 30hz capable monitor, i'm using internal limiter set to 30, and FTFF set to 0.01(added to p3d cfg). Just like alternative to 30hz monitor. It's not perfect, i guess the real vsync is missing here, but it works great for me. Also, a good explanation of original question about vsync and triple buffering: https://www.anandtech.com/show/2794/2

Try this, download http://www.majorgeeks.com/files/details/windows_installer_cleanup_utility.html Install it, run it, select FSX only from the list and click on "Remove". Like i wrote in another topic recently - Be careful with this tool, not to select anything else. Microsoft removed it from official support page, becouse you can easily run into issues if you accidentally select something else, which is a part of OS for example. But it is the only tool i know that removes every trace of FSX from system. And only tool which helped me to reinstall my boxed FSX every time, without problems

You may need to re-apply nvidia CP or Inspector settings, and rebuild your shaders - delete FSX folder under "C:\Users\YourUserName\AppData\Local\Microsoft". I suspect there cuold be more about this update, but it's worth trying, since you said AA is a problem

Sorry, but no. That wouldn't be ok in my opinion. But i'm going to contact them about this

Umberto, please don't take my post personally. At the time i posted this, i must addmit, i was a bit angry. Becouse i have just discovered - the other developer was modifying my P3D cfg files - options, for his product to look better in P3D, and this was affecting other addons and performance. They even used some cmd commands with addmin rights on my system(during installation), to modify some OS settings... So, i apologize if i sounded like accusing you of something(i probably did). I mentioned i do respect you and your work, and i love your products. But in my original post, i wrote "I belive this can be related to "CTD near Labrador", so this is why i posted it here and i didn't started a new topic or contacted you via support options." I have some news about this. I managed to get all FSDT products working without problems on my system. I'm still On Windows 7, no reason for me to upgrade now, until i build the new PC with the latest hardware. The solution for me was to uninstall the latest Windows rollup updates - i don't have any updates after 10 November 2017 installed right now, and everything works great. Even some other applications and addons which stopped working after windows updates, for example "PSXseeconTraffic(the latest windows 7 version)". I'm really happy i can use GSX and your great airports again, without problems. About C++ libraries... After reading a lot of C++ related, Microsoft's articles, i'm still not sure about this. After a lot of reading, my understanding is that C++ installer installs that anyway, or maybe - like in case of 2017 / 2015 versions, it just add the 2015 to the registry, i don't know if any files are replaced. But this alone(registry entries linked to the same file), it doesn't looks ok to me. I'm not sure about this, and i'm not a developer / programmer, but i do belive this can cause some problems. I do a clean reinstall of all C++ libraries after installing a new addon, and it works great for me. BTW, your products are working without issues with the latest(Major)versions only. Anyway, Microsoft advice for developers is to ensure compatibility with the latest available version, or to install libraries needed for your product, which you do, like all other developers. Nothing wrong with this. I did a test, a long haul flight, EDDF - KIAD, with PMDG 747 and all other important addons, without issues. Please let me know if i i can be of any assistance with "CTD near Labrador". I can do some tests, if needed. In case of some other addons, it was about net framework for example. It would be nice if we could know what is actually beeing updated with Microsoft rollup updates. I think i'm going to pass on all microsoft updates from now on, and i will keep my drivers and libraries up to date. I do not advise this with the windows 10, i'm using windows 7 and this is just my personal opinion.

That is a very good idea, i tested a lot of addons which are not officially P3Dv4 compatible, and almost all of them caused problems. My P3Dv4 is rock stable without them. I'm also getting better performance using XML metod for addons. I'm not sure i understand your initial question, do you want just to uninstall FSX in order to gain free space, or you want to use some of the FSX Addons in P3Dv4? If you want to just uninstall FSX correctly, i have Windows 7 too, and i like to keep it clean. It is important to me to keep the registry as clean as as possible. It can be done much much simpler, this is my way to do it: 1. This is optional, it is required for the last step, in case you will ever want to reinstall FSX on this PC, without reinstaling Windows. Right click on FSX.exe, select properties, then details(i belive it's under details, i don't have FSX installed anymore)and note your FSX version - the number. SP2 should be 10.0.61472, acceleration 10.0.61637 for example 2. uninstall all FSX addons you can first. Becouse some of them may need licence reset, in case you ever want to reinstall it. Some of them cannot be uninstalled via "Programs and Features", so left them in place for now. 3. After addons are uninstalled, uninstall FSX using Programs and Features. If Service packs are listed under Programs and Features, uninstall them first, then FSX. In any case, uninstall them all Restart your PC(otherwise, it won't let you to delete FSX folder 4. After restart, delete your entire FSX main folder. Let us know if you run into any issues - sometimes you are not allowed to delete it, becouse "some program is still in use". It's usually about fonts installed by an addon, which are now used by OS. Then, delete FSX folders under "C:\Users\"YourUserName"\AppData\Roaming\Microsoft", "C:\Users\YourUserName\AppData\Local\Microsoft" and "C:\ProgramData\Microsoft". Also, delete FSX files folders under "Libraries\Documents" and "Libraries\Pictures". Empty recycle bin. 5. install CCleaner free version https://www.ccleaner.com/ccleaner/download and use "cleaner" and "registry" section to clean all leftovers. You can backup your registry first, but i never run into an issue with CCleaner. I'm using it on daily basis 6. Now, the optional step - download this and install it http://www.majorgeeks.com/files/details/windows_installer_cleanup_utility.html Run it, and select FSX only and remove it. It can happen that only version numbers appear in the list, this is why i asked you to note this. Be careful with this tool, not to select anything else. Microsoft removed it from official support page, becouse you can easily run into issues if you accidentally select something else, which is a part of OS for example. But it is the only tool i know that removes every trace of FSX from system. 7. I'm not sure anymore if simconnect versions are uninstalled with FSX, but check under "Programs and Features" which versions are installed. You can install all of them again(and you should). P3Dv4 has installers for all simconnect versions, and they are located under "Prepar3D v4\redist\Interface". You shouldn't install RUS and JPN versions unless you are using those languages versions of P3D It looks complicated, but this will clean all registry entries too, which can be important for performance. If you think you don't need this, you can simple uninstall FSX via "Programs and Features" and delete all FSX related folders, listed above. I hope this helps

Ok, i have a few days off now, so i'm going to read all my notes about and i'll send you an email

If this happens in "hard on fps" scenery areas with complex airliners, it's absolutely worth it. This is how we should test performance. Of course, GA flyers should not be interested in this

You need to make a decision about this. I was in this situation. You should go for the best hardware available you can buy, all the time. Maybe you can wait a couple of months to save for something better. It should be a great upgrade BTW

Hi Umberto, I just spent a hour reading through all of the posts in this topic, and i have some own theories about this. The problem is, i cannot exclude FSDT products from any of them, and this is why i quoted you. I may be wrong, of course. The problem i belive i have with FSDT products in general are C++ libraries. I purchased some of your products - GSX, CYVR, KJFK V2 and LSGG, but i'm not using them, becouse every time i install any of them, i get instability and crashes. Not sure if this is some specific product related, or couatl, or addon manager, i never tested p3d with one by one installed. But this has caught my attention - every FSDT product is installing C++ libraries, without checking if more recent are installed: In the screenshot, you can see I updated all C++ on 29 april, anything that is installed on 13 May, is installed by FSDT(i checked it before and after running the FSDT installer). I had more recent versions for all of them. The 2015 version is now included in 2017, no separate installation is needed BTW. So, i had more recent version for this one too. This was causing problems with FSL A320 last Year, the FSL needed a more recent version and there was some conflict with 2 of them installed. There is a topic in FSL forums about this. So maybe some other addons needs more recent versions too, and there is a conflict with older version being installed. C++ are not well documented, but i belive if you have 2 versions installed(same year), it can cause conflicts. C++ libraries are not backward compatible - 2013 with 2012 for example. But the same Year versions(they are just updates)should be. Please let me know if i am wrong on this. Important: Any changes to my system and P3D(cfg files or other), should be referenced in a PDF or so, as a recommendations only, and not being done without my consent. This, in case you need some settings for displaying your sceneries correctly, or to perform better. I do belive you can set your installers to check if update is needed, to not overwrite a more recent versions of C++ or anything else. You can also add an option for advanced users, there are a lot of us knowing what are we doing with our systems. Don't get me wrong, i respect you and your work, i would just like to run your products without issues. The issues could also be on my side, so please let me know what you think about this. I belive this can be related to "CTD near Labrador", so this is why i posted it here and i didn't started a new topic or contacted you via support options. For all others - for now, i belive this has something to do with overloading, maybe the System, P3D engine, simconnect etc. FSDT for example, can be just a contributing factor. I'll test this routes now to check if i have any problems. I didn't tried this until now, since i didn't have any long haul planes, but i have PMDG 747 now. I do have a lot of addons, all of the ORBX, PMDG(737 and 747), FSL, and most of the top scenery providers. I will let you know tomorow about results, since i'm doing all the flights in real time(no time acceleration). This can be another factor in CTD's, you are asking your systems to do a 2x, 4x, 8x more calculations. For now, my bet is on the overloading. Everyone with this CTD, please post all of your addons and system specs.

The XML metod seems to give me the better performance on my system. I started moving all of my addons to XML. I "studied" P3D documentaion about this and did a lot of tests, and i do have a couple of observations and suggestions which may improve P4AO. P4AO is a essential tool for P3Dv4 in my opinion, and I'd like to exchange some thoughts about my findings with you. Let me know if you agree and if you prefer PM or a new topic(where maybe someone else can contribute). Yes, absolutely.

You should try to investigate this crash, and give us more details, maybe someone can help. I would recommend https://www.nirsoft.net/utils/app_crash_view.html also FSUIPC and simconnect log. Check Avsim CTD Guide, a lot of great info and fixes there. Also, give us more info - your system and addons in use

This should help: https://www.avsim.com/forums/topic/479802-how-do-i-post-a-screenshot/

Those are the settings inside P3D menu or both, in P3D and Nvidia Inspector? I noticed you applied this in Nvidia Inspector. It is recommended to use "in game" settings when available, they should work better then external settings, at least with less performance impact. This, applied in Nvidia Inspector will override P3D settings. Try to reset Nvidia Inspector to default profile, and set this in P3D. Start from there, do the test. SGSS is not available in P3D so you can add it later. I'm using default profile now. Do you have any other tweaks applied? Also, rebuild shaders(every time you add a tweak, or change P3D or Nvidia settings, update driver etc), just to be sure

Hi Morten, welcome to Avsim. I deleted the line which contains your product key, please do not post your keys in public

a great freware: https://library.avsim.net/esearch.php?CatID=fsxutil&DLID=182928

1. Try this - with RR to 30 Hz, set unlimited FPS. Also Vsync and triple buffering checked in P3D settings. This should be the best. or 2. With FPS limited to 30, add this line in your Prepar3D.cfg: under [MAIN] section FIBER_FRAME_TIME_FRACTION=0.01 This is the default value when you set FPS to unlimited, but it's changed to 0.33 when you limit your FPS, and there is a big FPS hit with complex addons. By default, with limited FPS, framerate is sacrificed for scenery loading and vice versa. The more CPU time is allocated for scenery loading. This is just a workaround for monitors which can't do 30Hz, like mine. The first option should perform better, in my opinion. Please let me know about the results, since i'm still investigating this Also, check my post, it took my FS experience to the next level with my HD monitor, and you are probably using HDMI: https://www.avsim.com/forums/topic/536191-nvidia-control-panel-and-hdmi-heads-up/?tab=comments#comment-3847385

Hi, i posted this yesterday Check if that can help you. Try also my 3rd post in that topic, those are two things you must change manually after every driver update. I think it's going to help you, since you are using hdmi output, like me. But your FPS seems to be realy low, my stays at 30(locked)almost all the time with PMDG, Maddog and FSL. It's probably about your settings or maybe some tweaks. If you want help on this too, post your p3d settings and tweaks(if any)you added

also, under "adjust deskop size and position", select the full screen. By default is "aspect ratio" i think. It fixed some issues for me, for example wing views where way of with default settings. The credits for this goes to Jim, i've read his post about this somewhere. Those are the only 2 default settings i changed. And yes, Rob, you should definitely pin that topic

I obviously missed Rob's post I had it this way(default settings)for a really long time. Today, it's like i bought a new monitor after i changed this

I found this today accidentally, with the new NVIDIA drivers(for quite some time now), default color settings are in compatibility mode for old TV's. So, if you are using default NCP settings, you are probably missing some "HD part" of your monitor / TV capability. I'm posting this, becouse it makes a huge difference for my HD monitor. I don't know if this is default only if you are using HDMI cable or not. This is what needs to be checked: In NVIDIA Control Panel, go to "Change Resolution" and check what is selected under "Output dynamic range". It should be "Full", and it's "Limited" by default. Just change it to "Full" and apply settings. http:// Like i said, it makes a huge difference. I hope some of you will find it useful

You need to increase the value to see an effect on texture loading times. 6 is default value. You can use multiples of 3 only - 9, 12, 15 etc. I prefer to increase TEXTURE_BANDWIDTH_MULT instead, since it's going to have the same effect - it's going to increase max allowed texture data per frame. With second option the actual increase will not be so big, and it's less probable to induce stutters and other problems. Try with TEXTURE_BANDWIDTH_MULT=150. It could be something else. If you are using ORBX Vector, disable "frozen surface" under "water features" in Vector configuration tool. This will cause your issue when enabled in P3D, it's a known Vector problem. It could be some new problem induced by ORBX Nederlands, i don't have it, so i can't speak about

Have you checked in Task Manager, the P3D is using the 100% of CPU or there is a maybe other process with high CPU usage too? Try to set windows update service to manual mode, and turn off automatic updates(you'll have to check / download them manually). There was a problem with windows update service some time ago, it was causing high CPU usage all the time. It could be the other process, this is why i said to check which services are using your CPU. This is a great tool for that purpose https://docs.microsoft.com/en-us/sysinternals/downloads/process-explorer
