If I include the really detailed locations like FlyTampa Amsterdam, then I would probably be lucky to scrape 15fps. As you are probably aware, this flight simmer does not do "mediocre" settings :wink: I know that probably sounds like an invitation to stutters, but this particular microstutter seems to be consistent at around three second intervals. That strikes me as some kind of process intervention, since I would expect P3D based stutters to be much more random.....

My i5 4690k CPU does not include a hyperthreading option.

I noticed these microstutters when I first tested P3D v4, but they seemed to have vanished after I deleted the Prepar3d.cfg file, Shaders folder, and SceneryIndexes_x64 folder (as per Poppet's instructions). However, they have since returned. I have just deleted the Prepar3d.cfg file again....and it occurs to me that (initially) this does not include all of the settings options that I need to input again after the original is deleted. That being the case....if this proves to be only a temporary solution, would it not point to one of the altered settings as the source of the problem?

I think I need to do some more intensive testing here, rather than automatically assuming that everything in P3D v4 should run exactly the same as it did in P3D v3......

Chris, I would seriously consider taking Kevin's advice and try v4.4, no one can say for certain if it will resolve your stutters, but it's worth a try.

You could do the client only update just to start out with, and see what happens. If you don't see any improvement, or simply just don't like v4.4 i'm pretty sure you can just uninstall the 4.4 client and roll back to v4.3, at least everything I have read says you can roll back to an earlier client....

I have just deleted the Prepar3d.cfg file again, input my required settings from the Create Scenario screen, and loaded the save file that I have been testing all afternoon (with the PMDG 737-600 NGX). Sure enough, the micro stutters were significantly reduced. Whilst I saw a handful of small stutters, they were more random. The regular "three second interval" microstutter seemed to be absent.

Before I make any conclusions regarding this (and run the test again for confirmation).......can someone explain to me what exactly happens if I enable "Use High Resolution Terrain Textures" from the WORLD options menu? What exactly does this do? The test that I am running includes UK VFR Photographic Scenery ground images, so does this option actually make a difference? If it does not, would activating it have any detrimental effects with respect to performance?

I will hold off on the "upgrade to v4.4" option until I have exhausted other lines of enquiry :wink:

Your last para is gold.

It seems you're trying to push your system further than its really capable of going.

Start default and push settings up slowly to see if you can recreate the problem. When youve done that add in some addons one at a time with default settings and see what impact they have etc....

You know what youre doing, suck those eggs mate...

high res ground textures will make the PR scenery use 513 sized tiles rather than 256 I believe.

Your 2Gb vram is likely to be a very limiting factor...wonder if your system is choking trying to cope with the high end visuals youre chucking at it?

I thought that the use of higher resolution textures for photoscenery was a v4.4 exclusive?

HDMI can do 4k at 60hz.

Hmm, then you are clearly better informed than me Matt. My own experience and that of others, is/was different. Perhaps it's something to do with HDMI 2? as I'm sure standard HDMI wouldn't give 30Hz. I'm pretty sure that was the case some time ago, but technology has obviously progressed since my own experience. Apologies if I have given wrong information.Thanks for the clarification. 😊

ah yea it is, in 4.3 it relates to landclass only sorry

Whatever the case, I have just completed my test flight at EGSS London Stansted in the PMDG 737-600 NGX, and......whilst there were a handful of minor stutters during the flight (normal for my system), the regular "three second microstutter" was nowhere to be seen, and framerates were pretty good. This was with 16x AF and 4x SSAA enabled. The graphics quality was also pretty good (with an acceptable level of texture shimmering, considering that I was not using my usual NVI 4x SGSS setting). Let's hope that this is the start of normal service once again :wink:

Sorry Howard I should have clarified further.  HDMI 2.0 is required for 4k/60hz.
