Hi guys, So whenever I'm over a significantly big mass of water, and I look straight or below, my FPS drops down by more than half (while if I look up to the sky my fps increases to 29-30fps Locked.) I had REXTextureDirect installed before this so I thought it may have caused this, but after reverting to default waters, the problem still persists. I also have DX10 fixer installed, should I mess with those settings also. Thanks!

So here is a little video about problem The problem is, that overall FPS in VC is 40-50. Even on high attitudes there is numbers like 60-70 FPS. But. The problem is, that I don't feel this FPS when move yoke. It feels like Yoke has only 10-15 fps. It's not smooth like in other aircrafts I have. Also spoilers, flaps, gear animation have the same problem. I tried to find topics about that, but every topic I found, cant solve my problem. So guys, if you know what to do, help me. Thanks. (My pc conf: i7 3770k, 8gb RAM, NVidia gtx 970, windows 10, game: Prepar3D V3.2.)

Okay so I've been having serious stutter issues for the past week or so. When flying with any type of clouds my frames would drop considerably. I am using both REX 4 and ASN so i tried turning the settings down for both of them. Nothing changed. Today I installed Nvidia Driver 353.30 as a clean install and deleted my P3D shaders folder. I went and started up a flight at Taxi2Gate KMCO with the QW757 and active sky next weather running. My frames went from 27-31 when sitting on the ground to 48-55 while sitting on the ground and went from around 16-23 fps with massive stutters while flying through or looking at big clouds to not losing any fps. This was just a post to help anyone else having similar problems or people who would maybe like to see fps out of there sim. I'm using P3D v3.1 by the way.

Hello everyone I know that FSX is CPU intensive which is why desktops are highly recommended. But, I really prefer laptops due to their easy transportation capabilities and spacewise. I am interested in two laptops. I intend to run PMDG 777 and 737. http://www.amazon.com/GL551JW-DS71-15-6-Inch-GeForce-Discrete-Graphics/dp/B00T7XRH2A/ref=sr_1_1?ie=UTF8&qid=1434478111&sr=8-1&keywords=asus++ROG+laptop http://www.amazon.com/dp/B00QHD8N6C?psc=1 The only major difference is the GPU. The first one has GTX 960M (which is cheaper) and the second has a GTX 970M. Anyone have an idea if the difference of these graphic cards will have a noticeable different FPS count? If yes, about how much of a difference? Thank you (first post)

Dear all, Does anyone uses the external FPS limiter for the Radeon graphics card on the Windows 10 operating system? If so could you please share your experience with the rest of the community about setting it up in Windows 10 and a like. The reason I'm asking this is that before Windows 10 I could use the software Radeon_external_FPS_limiter (found it on Boyote tweaking site), but since Windows 10 the mentioned software doesn't work. Also is there some other similar software that could work on Windows 10? Thank you all in advance for the helpful tips and suggestions. Safe simming Marko

Hello all, I would like your opinions on a graphics card for P3D that will best suite my rig. My current setup is as follows: CPU: Intel Core i7-4790k @4.0Ghz (NOT willing to overclock) GPU: AMD Radeon R9 290 (NOT X) Motherboard: Gigabyte Z97-HD3 Power Supply: 800w The case has got room for a full sized GPU With P3D I use: All PMDG's Aerosoft A318-A321 Payware scenery for most popular airports (EGLL KJFK CYYZ) With my current GPU while flying into the airports listed above^ in the Aerosoft A321 I get about 15-20fps. 15-20fps I can deal with, but it is when I step into the PMDG 737 that I get frames in the 10-16fps range. I have all the drivers for my GPU, and have tweaked P3D (Which has helped some), and I have the latest updates/patches to P3D. I think it might be time to retire this card. I was thinking something along the lines of an EVGA 970? If there is anyone reading this with this current card that sims on P3D, I would greatly appreciate a response. I don't really want to go above $450 CAD. Thanks for your help. -Thomas

Hello everybody, When it comes to optimizing FSX' performance, some of the recommended tweaks are to alter the Fiber Frame Time Fraction in the fsx configuration file. There is also a frequent discussion about whether to limit FPS internally or externally for a smoother flight experience. Some users report that using an external limiter causes more blurries, while many others experience a drop in FPS when using the internal limiter. In my experience, the drop can be quite substantial at busy airports. Whereas running FSX with unlimited FPS yields around 22FPS at KORD with lots of traffic, limiting FPS internally to 30 (or any other value) reduces the FPS to 14 on my computer, which is a huge percentage loss. I was wondering why the internal limiter would put so much strain on the FPS, even though the graphics did not seem different. As far as the Fiber Frame Time Fraction tweak, it is supposed to adjust the "fraction" of CPU processes that are dedicated to rendering the terrain and scenery (that's how I understand it). Playing around with different values didn't make much of a difference, until I was baffled by an unexpectedly low frame rate during cruise on one of my flights with the Majestic Q400. I use ORBX Global + OpenLC EU, and it often happened to me that textures became blurry on approach with autogen objects popping up very late. Increasing the FFTF value (default is 0.33) was supposed to sharpen the textures quicker, but the difference I saw was marginal, if any at all. At this point, I was running FSX at unliimited FPS. One time I increased FFTF to 1.0, but I had a hard time finding a significant improvement. Another time when I was at cruise altitude (having 40 FPS), I limited FPS internally to 30, and to my shock, the FPS plunged to 16 or so, even though I was still cruising at 19000 feet. However, it looked like even from that altitude, the FSX was generating autogen objects on the ground (a quick switch to top-down view showed crisp textures and all objects). On approach and landing at LFPG, FPS showed a one-digit value, and I thought that this was not normal behavior. Studying my fsx.cfg, I found out that the FFTF value was still set at 1.0. I was wondering whether there was a relationship between activating the FPS limiter and setting different FFTF values. This is when I figured out that apparently, this tweak shows no effect when FPS is set to unlimited. I ran a test to check the initial FPS on the runway of a selected mid-size airport (KGSP) at different FFTF values with both limited (99) and unlimited FPS. Here are my results (the FPS values indicate approximate ranges): FFTF value FPS limited FPS unlimited 1.0 34-35 70-74 (default) 0.33 56-58 70-74 0.25 60-62 70-74 0.20 60-62 70-74 0.10 67-70 70-74 0.05 70-73 70-74 Let me also add that when limited internally, the FPS hit occured regardless of whether I would set the target FPS to 60, 99 or any other value. This result shows to me that the FFTF tweak is only effective if the internal FPS limiter is activated. When FPS are set to unlimited in the graphics option, the sim apparently behaves like it is running on a very low FFTF value. This explains why the sim is prone to blurries if FPS are not limited internally or limited externally, as reported by many users. It also explains why many users who don't apply the FFTF tweak see a huge FPS drop when they use the internal limiter - that's because the default value is set quite high. Even though these tweaks have been known for years, I thought that you might still be interested in these findings. You now know that in order to lessen the impact of the internal limiter on FPS, the FFTF value needs to be reduced. If the simulator can't reach the set target FPS, you will likely see blurries and/or late autogen rendering. I have experienced that if the target FPS is below of what your PC is capable of running at unlimited FPS, the resources will be spent more on scenery, and textures will be adjusted to look sharp quicker. If you run at unlimited FPS, then apparently FFTF has no effect. If you are interested, you can try that experiment on your computer and let me/us know if your FSX shows the same behavior.

Hello, I've noticed some FPS problems with the newest fixer e.g. when I fly with the Aerosoft Airbus. The problem are the shadows in the VC. Can someone tell me how to get better frames with shadows in the VC? -Sweetfx; NI for my GTX560; REX4; ASN Cheers

Hi all, I seem to have got my sytem's "stutters" under control and thought I'd share a little of what I learned. The problem: I was getting framerates of 50+ though quite erratic but then I'd pan the camera or pull a sharp manoeuvre and I'd get horrible, very brief fps stutters where the image would breifly freeze, jump then be fine until the next manoeuvre. What works for me: I had a look at his page: http://www.prepar3d.com/SDKv2/LearningCenter/getting_started/performance/general_performance_tuning.html - tweaked a little didnt really know what the effects were but got a better understanding of what these entries in the cfg did. Then I looked at this page: http://www.venetubo.com/fsx.html - uploaded my cfg, was not confident enough to paste their suggest cfg file in full as it seemed to not really account for P3d 2.2 but i did however pate the entries it said it had ajusted into my existing Prepar3d.cfg. -- this helped a bit but didnt fully solve the issue Then looked at my Gfx card's control panel. For me, I have 2 crossfired AMD FirePro GPUs (it's the new "trash can" Mac Pro) Here I turned everything to "use application settings" as everyone suggests, turned off "wait for verticle refresh" and "Open GL tripple buffering" and this made the biggest difference; I turned off AMD crossfire's "Frame Pacing" Now almost smooth as silk 40+ framerates in a nice addon AC at a nice Orbx Airport... happy days!

Afternoon everyone. I would like to ask the beta testers of the 777 SP1 if they have noticed any performance improvements compared to the current release of the 777. I've always encountered performance issues with this addon and hope that the said issues are remedied with the upcoming update. Let me know. :) Thanks, Stephen Hobson

Hi all - I'm already aware that people have had issues with FPS drop when the mouse is on screen, but my issue is in reverse :huh: As soon as the mouse auto-hides itself, my FPS drops to around 10-12. I wiggle the mouse and it pops back up to 28-32. It didn't always used to do it, it just started doing it one day. Drives me nuts! If anyone can help or offer a solution, it would be greatly appreciated. Thanks FSX on a standard HP Pavilion laptop, Triple-core AMD Processor with integrated graphics, 3GB Ram - Runs like a dream

Would these computer specs work well in fsx (thinking of building a custom pc) Intel i7 3770K (3.5 Ghz 3.9 Ghz Boost) Asus P8P67 Deluxe Motherboard EVGA 760Ti 2 gb Graphics card 200gb SSD 8GB DDR3 Memory 850 Watt Power Supply I am still deciding on a case, any recommendations are welcome

I've been tweaking - as usual - FPS on my sytem and have a consistent 30fps using the settings Ryan posted for Nvidia Inspector on the 4Xs settings. CPU = 4.0ghz 8-core GPU = Nvidia GTX 660 VAS monitor has me w/ 1500mb free - so no issues there. I have 30fps outside the aircraft. In the VC if have a frustrating 9 to 15fps - over land, over water - doesn't matter. When I open a 2d popup in the VC, such as one of the FMC's - FPS jumps up to 25. I doesn't matter where I drag the 2D popup, I have a big FPS increase wiht the 2D window open. Any logical explanation for that? By the way, I have 8fps in the performance section for the VC displays. Help/suggestions? Thanks.

Hey guys, like I said, I just got P3D V2. It looks nice but still feels like graphically, it's not amazing (but thats coming from an XP 10 user ). I tried to find a thread on how to configure Prepar3D for great visuals and performance, but can't find any. I have an i5 2500K OC 4.3ghz and a GTX680 2GB. I have NI inspector so i'm not sure whether i should use that or not, and also i'm using windows 8 so i'm not sure where i stand on the whole V-Sync subject, however, i turned it on, and noticed an FPS decrease. Any help would be appreciated!

Hello Ladies and Gentleman After much deliberation (and a good discount), I bought XDisplay to use with FSX. The problem I'm having is, as soon I move any panel (even the default Cessna GPS) to the IPad my FPS drops to 1. I close the panel, the FPS return to normal. Does any have successfully used XDisplay with FSX? Note; I'm aware of the bug with NVidia cards, and I successfully applied the workaround. The thing is if I use this method, the lag is too much. I've seen a video on YouTube of a Guy using with almost any lag. Thanks for any help I can get. Regards,

Greetings all! I need your help in recommending what to upgrade to get FSX running smoothly with the NGX and upcoming 777. Currently with my setting nearly maxed I can get roughly 45-50 FPS with a default c172. As soon as I switch to the NGX it drops to a mere 12-14 FPS. Here are my specs: Intel i7 920 @ 2.67GHz EVGA X58 motherboard 6GB(3x2GB) RAM DDR3 Tripple channel at 2122.6 MHz NVIDIA GeForce GTX 550 Ti 2GB So, I have a Newegg account and plenty of credit to spar with them. What needs to be upgraded in order for me to have a steady 25-30 FPS with the NGX? I run REX, TacPack and the Warthog GUI software in the background. Thank you all in advance. Best, Kurt Collins

Hi, People will be able to help me? I use rex when i put a little of cloud´s i have jumps on the video or low fps, :angry: :angry: In the rex i have the next config ir you lock the image. In the Fsx config i have the low options for wheater Mi Grapics gard Ati HD 6770. Thanks for your help!!!!...............

Hello (Apologies if this is the wrong area to post such a thing) I bought the Airbus X Extended yesterday, but only got round to trying it today. First impression is a promising aircraft that I would love to fly, with one major flaw. Unlike the NGX in which I get 22fps constantly (locked internally at 22) no matter where I am, the AXE likes to bring that down to 9 fps for some reason... The maximum fps I have been able to achieve with it so far is 12 fps............. I just wanted to ask if this is a known problem that other people have too, or if its just me, because right now, I'm back with the NGX untill some sort of HOTFIX has been created:/ sorry aerosoft.... Advice appreciated (PS I have this hotfix installed but still no joy...:( http://forum.aerosoft.com/index.php?/topic/60728-hotfix-1-released-am-211212/)

Aime Leclerq is an extremely skilled FS-product maker. I am curious to know if the products that are made by "Oscar (Aime)" are hard on FPS, even if I try the lowest version offered. If anybody with any of those products can give me any info on whether it hurts FPS or if it's like default or not. ~Thanks!~

Hey guys! I just got enough money to buy myself a new motherboard (P67). I currently have a H67 (which doesnt support OC.). I have intel i7 2600K at 3.4ghz, AMD Radeon 6870, and 4BG ram. Right now if i use the pmdg 737 at paris charles de gaulle airport along with paris VFR scenery i will get 19-25 FPS and with and other plane around 25-30. So im thinking if i buy my new motherboard i will be able to overclock to 4.2 or 4.3ghz. Will this really improve my FPS? Because i plan on getting the pmdg 777 and that is going to be a HUGE FPS hog. I just dont want to waste my money on something that wont work. So if any of you can tell me if it will work that would be great. And also if you recomend some safe overclocking speeds that would be great! Thanks guys!

Hi there, I've been having extreme problems with my frame rates in FSX after purchasing the PMDG 737 NGX 800/900. After following all the recommended setup instructions, I am only getting 1, maximum 3 fps! Here are my system specs and other info and if anyone has any suggestions for the settings I should use in FSX and in the fsx.cfg, please let me know: Installation: FSX SP2 Processor: Intel Core i5-2410M @2.30GHz (4 CPUs), ~2.3GHz (see attached photo) Memory: 6GB RAM (6144MB) OS: Windows 8 64-bit edition HDD: 674GB DISPLAY Device: Intel HD Graphics 3000 Approx.

Hello everyone! Just so everyone knows, I am aware that if im using all those addons ill be getting bad fps but not as bad as i thought. So i just got accepted into Qantas Virtual so ill be doing my flying in Australia, and who better for scenery than ORBX?! So I load up P3D, select YBBN (Brisbane, with all patches and I have taken out all the major FPS killers in the control panel except for PeopleFlow.) and I load up my 737. My FPS during the day time is only at 20 at the gate with the plane systems on! Now ill give you a series of tweaks that i did to my CFG file and system specs, also, should I turn the the resolution on the 737? Will it look really bad? Used Bojotes tweak tool for fsx, For the bufferpools i replaced their number with 0, and i also added the Fiber frame fraction tweak and set it at 0.33. Other than that I set the ORBX effects to Day mode. System specs: Intel core i5 2500K 4.5ghz AMD Radeon 6870 1GB 8GB RAM 750 Watts PSU ASROCK P67 MOBO FSX is on a 1TB hard drive And numerous addons. Is there maybe something i missed or can do to improve my frames when flying in australia? Because in Europe I get great frames, i dont check the number but get between 25 (lowest) to 40 with the pmdg. Thanks!
