    I watch the forum pretty close and have not seen anyone post on this yet so sorry if it's already been discussed. Has anyone else noticed that when you install scenery into the library it stacks it top to bottom as one would expect from FSX but the priority number to the right of it is going from high to low? I am wondering if this might be causing the texture issues I have been seeing using FTX Global and other add ons? Perhaps its what's causing the bumps on take off rolls I cant explain; Mesh having a Higher priority than scenery could cause this and My FS Global mesh was one of the first things I added. Off to do a little testing...

    I had to try it of course I did. This FSX tweak is recognised by P3D. My AMD card generally averages around 70% - 80% usage. Using the BUFFERPOOLS tweak it will max out instantly and repeatedly, the fan goes mental and the PC wants to take off! It does absolutely zilch for performance, apart from using more electricity. Who else wants to own up to trying it

    Default settings V2.0 i2500TO 3.3ghz, 8gb memory (1600), nVidid 550GTX 1gb memory I start V2 at any airport and get what I consider good FPS. KHQM ORBX airport 45FPS. New York viewing Manhattan 35FPS. Change airports still good FPS. Note: Video card GPU usage around 96% as was predicted. Now if I go to the display setup screen and do nothing more than cancel my FPS drop to 50% of previous value. PLUS the usage on the video card GPU is now in the 70% range. Fiddling with options has so far had no effect. This drop of FPS when using the display setup is fully repeatable.

    I am replacing a 570 with a 780ti this evening. What exactly am I supposed to delete from P3D before I run P3D for the first time? Something to do with the shader cache, correct? Is it the entire ShadersHLSL folder? A sub folder or file? Something entirely different? Please forgive my base ignorance.

    Hi folks For those running the Estonia Migration Tool how did you get it to install? I just downloaded and activated the product ok but when I start the installer as Administrator I get a popup that states: "Warning: Prepar3D was not found. Prepar3D registry entries are likely corrupt." The install continues and I choose my destination folder, press install and get the following error message: "Error: simulator not found." The installation then hangs and I have to abort it. What gives? Anybody have any suggestions? Thanks John

    This one happened yesterday twice in a row: takeoff with A2A 172 from Catania Fontanarossa (LICC) with heading about 040 toward Reggio Calabria (LICR). After 15 minutes or so of a perfect,smooth, 36 fps flight, cockpit shadows go berserk, then some hiccups and bang: OOM. Tried it again and had the same result. So today I tried the same flight with my resource monitor open and found out that the shadow artifacts and hiccups occurred when my VAS was around 2.6 GB and GPU memory around 3.5 GB (I have a 4 GB 770 card). Then the OOM occurred with VAS @ 2.6 GB and GPU memory @ 3.8 GB. I tried again the same flight with the stock A36 and had no shadow artifacts, no …

  10. I was wondering if anyone has tried P3Dv2 on a laptop with specs similar to mine. I know with their return policy, I can try it for "free", but I'd like to at least know ahead of time if it's worth my time or not. HP Pavillion Dv6t Quad Edition, Win7 (64), i7 2.0ghz (2.9ghz w/ Turbo Boost), 1GB Radeon HD6770M, 6GB RAM For reference I get steady 30 fps (limited externally) in FSX right now at ORBX KHQM in the stock C172 with autogen and scenery complexity set to "Very Dense", REX and "Fair Weather," water 2x low, and all traffic on but set pretty low. The A2A C172 with drop the FPS down to about 25 fps. Ideally, I'd like to have same visual quality I have now (even if…

    I have this annoying blurry texture loading problem in P3D2. Some times it's obvious that P3D2 is struggling to load the texture fast enough, but more than half of the time it almost seems that P3D2 forgets to load full texture. For instance, in cockpit view I see all ground textures are ok, then I pause the flight and switch to several external views like spot or aircraft camera. In some views the ground textures are really blurry. I have to wait forever for them to be fully loaded. Also when I switch back to cockpit view those ground textures may become blurry too. It also happens in normal flights. Last night I was flying extra 300 from KSFO to downtown San Fra…

  14. Ouch, what I'm seeing is nightmarish regression to 1992 quality, only worse! I looked at the default water, then installed several textures from REX E+, tried REX's DX10 wave animation. Long n short--in a word, heinous! One poor lad reported on the LM forum that his workaround was disabling HDR (and/or tess), but ouch, that's not going to happen here! Help! I think I'm running the nV driver just prior to the current WHQL FWIW. I'm hoping someone has figured this out as I can't believe this was intended by LM. I have tried all in-sim water slider settings. Also, starlight reflects off of ocean water and that is nasty too!

    This is mainly for the guys that used Word Not Allowed's 1/2 refresh rate in Inspector in FSX. Set 30FPS in FSX for a 60hz monitor for this to work correctly. This setting made FSX super smooth and stutter free for most people including myself. U noticed this most at takeoff or landing or anytime at low elevations. Watch the scenery scale by the wing from the VC and u will see a major difference in smoothness when enabled. Once u use it there is no going back. This setting will not work with P3d however. Most likely due to comapability or this hybrid full screen bs. The only way I can replicate it is to run at a locked 60fps. However this is not going to happen …

    Howdy, I'm on the fence w/ using the migration tool--primarily from not knowing if it's possible to UNINSTALL add-ons thru the same tool WHEN FSX is installed on the same machine. Yeah or Nay? I'd like to wait for 'official' versions of add ons but that will be potentially a long wait. But when they do come out I'd like to be able to uninstall the migrated versions and install the official versions. I have FSGenesis mesh for FSX. Would it work w/ Estonia too? I am assuming the default mesh is low resolution as w/ FSX, yes? Thanks in advance!

    After a week of testing and tweaking and fooling around with all the options I finally started to actually do some flights this weekend. And after spending a saturday afternoon and a sunday morning doing so, I have to say I had to change a few settings... You could say I went back to reality. ^_^ The main step 'backwards' is that, despite my shadow tweak, I had no other choice than to disable buildings and vegetation shadows... Although I got good results with those enabled during my tests, I came to the conclusion that during regular flights, things became sluggish, even when fps stayed above 20. The main reason for this is that I installed the A2A C172 (which wo…
