For P3Dv4, you should never ever use the Nvidia Inspector.  Lockheed Martin built the graphics settings into the P3D.cfg.  I provided my settings to another member today and here they are - https://1drv.ms/f/s!AhI63XLVLrGnhGDxBE3LGnk_qfIf. 

In the Nvidia Control Panel, make sure the "Adjust Desktop Size and Position" is set to Full Screen.  Default value is Aspect ratio.  In the "Manage 3D Settings" for Prepar3D, I have changed the following settings:

Texture Filtering - AA sample - ON

Texture Filtering - Negative LOD bias - Clamp (this reduces stuttering/shimmering but not completely).  You will never ever see stuttering or shimmering gone completely until the P3D engine (which is an off-shoot of FSX) can be changed.  Right now they have some limitations based on the Microsoft licensing.

Texture Filtering - Quality - High Quality (you might try Performance or High Performance too)(I use High Quality as I have a powerful system).

Texture Filtering - Trilinear optimization - On (believe I turned this on as the Guru - Rob Ainscough recommended it somewhere and I only listen to Rob when using P3D).

The AVSIM P3D Configuration Guide was originally developed for P3Dv3 backwards.  It was not developed for V4 but many of the suggestions still apply.  I will attempt to update it in the future as Rob has a real time job and is not fully retired like me.  He also likes making YouTube videos to show off a new product.

In regards to getting 50+ fps consistently with your system, it's most likely not going to happen (can't just say not).  I cannot get it to happen consistently with my powerful system (see my signature for system specs).  I can easily get up to 300 fps with default scenery, aircraft, and settings (no sliders touched).  When you add the eye-candy, things go South fast.  The higher the settings you use in P3D and the more eye-candy software add-ons you install and use, the less likely for success.  IMHO, anything over 30 is pure unadulterated success and you have achieved the ultimate in flight simulation.  Anything less than 15 is reason to be concerned but only if it is for an extended period of time.  For instance, here is a flight from FSDT KLAX to FlightBeam's KPHX over Orbx SoCal and MSE UltraHi Res Phoenix and MSE Arizona.  I was flying the PMDG 737 and enabled ASP4/AS CloudArt.  UT Live was enabled.  Weather was raining at departure and partly sunny on arrival.  This is the FSUIPC5 report on the flight:

Minimum frame rate was 5.7 fps, Maximum was 61.5 fps
Average frame rate for running time of 2697 secs = 44.2 fps
Maximum AI traffic for session was 301 aircraft

I do not recall when the sim went to 5.7fps.  I'm certain it was just for a fraction of a second and probably while setting up the flight or while things were loading.  The flight was smooth and enjoyable.  The scenery textures were mostly crisp and clear but not like in real life as that will never happen with today's technology.  Now, an average of 44 fps is pretty darn good.  I even flew over Orbx's KPSP (Palm Springs) enroute!  When flying over PSP at FL290, I do feel stutters but nothing to be concerned with.  Enjoy the hobby of flight simulation and quit the tweaking.  If there was the 'holy grail' of tweaks or settings, you can be sure they would be well-publicized and they are not.  Just remember, because systems are running faster and faster and providing better performance, the eye-candy developers are hard at work to give you even more eye-candy as their mission is to make their product look stunning and they really do not test for performance purposes. So you have to keep your P3D settings set pretty conservatively to really enjoy.

Best regards,

Jim
 

 

 

 

 

Thank you very much for the tip with the "Adjust Desktop Size and Position" is set to Full Screen. 

I was always wondering why i have such a bad picutre quality with my 32" 4K Gsync Monitor, since i changed this setting, the picuture is as crisp as i expected it for 4 k.

Thanks for your comments.  I suspect you meant to say "not as crisp".  If the picture is not as crisp with full screen setting (and it should), then change it back to the default of Aspect Ratio.  I have no explanation for the reason why your setting is not working as well as it does for me.  Just know it improves things for me.  Perhaps it is another setting in my P3D.cfg settings that did it for me. It also could be the fact you have a 4K Gsync monitor and I do not?  I make suggestions based on my experiences just like many others here in these forums.  That's what community forums are all about, to provide suggestions for the community they can try.  I wish there were settings that worked perfectly for everyone who uses P3DV4.3 but, like humans, computer system components are not the same for everyone.  I do know one thing that will make things crisper for you is disabling Hyper-Threading in your BIOS and getting rid of any AffinityMask tweak (I suspect you do not have that tweak but mentioned it just in case).  Unfortunately, for most MB manufacturers, HT is turned on by default in the BIOS.

no as i said 🙂 since i changed to Fullscreen from aspect Ratio the picture is crisp:-)

 

with the Ratio setting i thought my monitor is damaged.  now with fullscreen everything is as i expect it 🙂
