As far as TEXTURE_SIZE_EXP=10 goes, it does double the size of the textures which is the reason for the slower load times. While I love the visual from it, the load time drives me crazy seeing it takes twice as long to load. If your patient and have a powerful video card than its worth using. 

Several months back I saw Rob A on YouTube using TEXTURE_SIZE_EXP=9 with High Resolution Textures checked. I wonder if that does anything visually?

Slower load time? Wow,have enough time to make coffee and grab a sandwich! 🙂

Detailed as always Rob, thanks. One question for you - I am thinking of going SLI and adding a second 1080ti instead of shelling out a grand or more for the new cards. Does SLI really help P3D and how?

I'll get back to responding to these questions later today (Sat - PT) as I've got other duties to attend to this AM.  

I would encourage everyone to experiment with these settings as it will NOT cause your system any "harm", worst thing that could happen is you run out of VRAM which might cause a CTD.  Just remember anytime you CTD wipe out shaders and sceneryindexes64 (they get recreated on next start).

Yes, 1024 textures will take much longer to load and the more add-ons you have installed and "ACTIVE" (key being active) the longer it will take, if you want to shorten that time either uncheck the add-ons not being used (via UI Add-Ons or via Scenery Library).  Remember, P3D (and FSX for that matter) loads the ENTIRE planet ... many people have mistakenly thought it only loads what you see, that's NOT correct.

SLI does help P3D IF you run GPU heavy loads, however be aware that SLI increases CPU loads (in my experience CPU loads increase about 17% in P3D) ... what that means is you need to find the balance ... if you're already at 90% CPU load with one GPU adding a second GPU is going increase your CPU load so you end up pegged at 100%, then you'll have to reduce CPU intensive loads like (AI Traffic, Road/Boat Traffic, AG Buildings) ... so it's give and take, if you like better AA and better performance with Dynamic Lights and Dynamic Reflections but don't mind giving up some AI Traffic and a notch less AG buildings, then SLI "might" be worth it.  But I can't stress enough that SLI will increase CPU loads (that's always been the case and isn't P3D specific).

Gotta run, will get back to this later today.

Cheers, Rob.

Very Interesting. Like many others I have tons of scenery installed. I've been thinking if I should only activate the scenery that I'm flying too/from would be the way to go. I wonder if using Add-On Organizer or the UI would be the way to go. My example would be, if flying in the US, than I would disable the 3rd party scenery outside the US.

I do that all the time. In the Lorby software I set up groups of sceneries (e.g.USA or Europe, etc.) and I only activate that group which I am flying in.

Do you include the Orbx scenery?

LORBY 'groups' work well with Orbx  ....well I only have the North America regions+ a few airports.

Yes as said above.

Just ordered 3x 55” 4K monitors to replace the 40” - 32” - 32” 2K monitors.

Instead of 2 views I will return to 1 view with LM Disrtortion Correction to obtain max fps...

If the 2080Ti can’t handle that much of pixels I will run them at 2K till I can buy a second hand 2080Ti somewhere in the future.

Or in the meantime I can run them each slightly higher than 1920 x 1080...

Sure, it takes about 4 minutes for a flight to load!

Hi GSalden-

I'm running 3x27" monitors. What is this exactly?

Hopefully not three separate windows dragged to 3 separate monitors. Tried that one a ways back and was a bust, fps wise..

Thanks,

Mark

And MAX_TEXTURE_REQUEST_DISTANCE=32000.0000  (default is 1000.00000) ... both of these should already exist in your prepar3d.cfg.  

[Graphics]
ENABLE_MEMORY_OPTIMIZATION=0

reduces malloc for AG but increases memory usage

Could it be that these settings alone are pretty hard on FPS? I directly included this cfg tweak after updating P3Dv4.4 and somehow my FPS are not a single digit higher than before. I thought I would be fine with my 1080Ti (11GB VRAM) and 32GB system RAM...

These settings MAX_TEXTURE_REQUEST_DISTANCE, ENABLE_MEMORY_OPTIMIZATION=0, MaintainSystemCopyOfDeviceTextures=0 should have no impact to FPS.  The setting that will have an impact to FPS is:

SCENERY_DRAW_DISTANCE=128000.000000

But the catch-22 is SCENERY_DRAW_DISTANCE setting will also be the best option to prevent unloading/loading of textures ... when I have a chance I'll demonstrate the effects of each of these settings ... but that might be after Dec 14th as I'm swamped with work and life at the moment.

Cheers, Rob.

Max single resolution supported is 7680 x 4320 (8K).  If you don't run those monitors at native resolution you "might" be subject to blurry image quality.  Also be aware P3D doesn't support desktop different scaling on more than 1 monitor (they must all be the same scale value) and the scaling only applies to things like text/menus, the in flight will still be at native or whatever resolution is selected.  So you'll have to run the monitors at non-native resolutions which is where you might encounter less than "sharp" image quality.

Some monitors can do upscaling of lower res to 4K ... I think you need to set the monitor into a "different" mode in order to accomplish "upscaling" when connected to a PC.  This "might" produce better image quality and less FPS hit ... but "I think" you may need to change to YCbCr format (not RGB) ... here is a good article on YCbCr.

Desktop scaling works very well on smaller 4K monitors and can really make text look super sharp and clean since it still operates at 4K res ... but you do lose desktop real-estate when scaling.

Cheers, Rob.
