The Prepar3d Graphics settings UI page will tell you what GPU it's recognized as viable (if more than one GPU, the dropdown will list them all).

Motherboards will vary on how they enabled/disable embedded GPU ... in the past "on-board" is a common identifier or "Internal Graphics" or "Integrated Grahpics" or "IGFX" or "IGD".

Check NCP also if you're using nvidia, make sure monitor settings are correct, RGB-Full, refresh rate, etc.

Cheers, Rob.

Hi Rob,

just an update, checked the bios and the interstates gpu is disabled.

monitor settings are correct.

im stumped as to why drop down menu is overlapping the shift z text and blurry whilst panning.

But as I mentioned before if I rebuild the cfg it’s fine.

when i go into full screen and then close the sim. Restart the sim. 
bam it’s messed up again.

thanks for your help.

460.79 is the one I use without any errors. Maybe a good starting point. Good luck. Marcus

I'll give it a shot if my current flight fails. I am doing the same ~2hr flight from MSPS to KJAC in the NG with an IFR flight plan loaded and so far so good. I think the key for me is to keep texture resolution at 1024. Anything higher is simply not feasible with my 2080, particularly with PMDG, even if my vram says otherwise!

I have my Text.Res also set at 1024x1024. And honestly, depending on the planes you use, differences are sometimes hard to see. Also a little bit depending on which Airports you use.

With 460.79 I did not have a single CTD. I tested this with stock and 4 addon planes and all my addons are active. Have tested this round about 100+ hours! 

All the drivers after 460.79 did bring me more stutters or the last one, HF 461.33, which should solve stuttering in VR, does bring me the device hung error.

So this DXGI error is not motivating at all if you are not knowing what exactly does cause it.

I have found the following issues which CAN cause them:

1. VRAM spikes (playing with settings in P3D) after starting a flight in P3D
2. Out of VRAM after starting a flight in P3D (never bin an issue for me with 24GB)
3. older trueglass.dll
4. older reallight.dll
5. Bathemetry on
6. Vegetation shadows casting
7. Nvidia Driver

Having so much causes can drive someone really insane.

I do hope you get sort it out. LM is still working on his VRAM management, as they stated in one of their feedbacks at their support forum.

Also noticed this but i havent had a hung crash in the NGXU,FSL,QW787 wirh 4096 4k since disabling trueglass and reallight. 

Only crash for me sometimes is when saving. The file gets saved so it must be a conflict addon.

For me the hint with disable game mode worked till now. 

Tried to start a flight from LOWS to EGKK with FSL A320 and as soon as the flight was loaded I had a device hung. 

Now I`m in the preflight prep with FS2Crew since 20 minutes no issiue so far.  

I use a 6900 XT

Are you using any sort of desktop scaling or something that might be scaling fonts?

Can you provide a download link to your Prepar3d.cfg (the bad version)?

Do you have "Disable fullscreen optimizations" checked?  (right click, properties, on Prepar3d.exe?

Cheers, Rob.

EDIT: I'm assuming you're not using any 3rd party software that might be modifying the Prepar3d.cfg?

Disable fullscreen optimizations" checked =yes 

3rd party software??

heres my cfg, sorry i dont know how to attach the cfg file on here.

I am going bananas trying to figure out this issue.

Yes I know, It’s not that big of a deal, sorry for being OCD about it.

but that’s just me.
Any one else have any ideas?

just to Clarify when I rebuild cfg it’s fine.

but when I restart P3d and go into full

screen it then messes up the scaling

cheers

What hope do we have when a 6900XT gets hung.

It just shows that it probably doesn't have anything to do with VRAM.

Yeah...certainly not always. I know this for a fact, because the other day I had a hung with 4.3/7.1. 

Not sure if it‘s related
 

But maybee it could also help to start active sky after the simulator and plane is loaded.

at least I had the experience that sometimes it helped. 

SwapChainAllowTearing=0  ??   (Default = 1)
Location=0,0,3840,2160,\\.\DISPLAY1   ?? I've only seen that on LocationFullScreen
??? Should it be set to 1?

 

unchecking disable full screen  optimization has the same effect on full screen.

I did rebuild the cfg  no mods and it loads in window mode just fine with text and menu.

i close the sim and then restart.

load in windows mode, all fine except if I want to change setting or aircraft I get device hung error.

Changing to full screen mode and restart it messes things up again with menu and shift z text.

i did notice something strange thou.which i have not noticed before as I do not use the default aircraft. Only for testing.

one of the f16 has a black cockpit no textures.

ive tried reinstalling the content , but to no avail.

could this be causing issues?

 

thanks for taking the time to help.

mike

Just an update, so I uninstall an deleted all folders associated with v5.1 hf1 

reinstalled with no addons 

and same issue persists.

is it a corrupted P3d installer?

Shall I re download and reinstall ?

thanks 

mike

I have p3d V5.1 hf1. With 461.40 nvidia drivers I always got dxgi error. I rolled back to 460.89, no more crashes. Il'' try 460.40 and see what happens.
