I've finally gotten a chance and play this game for the first time today. Upon character creation I noticed polygon glitches in the background. I figured I'd just power through to get through the intro and see if maybe it was the area. Same issue throughout the house, outdoors when you run to the shelter, and even worse so in the shelter. I gave up after that point.

You can see a video of what I'm seeing here: https://www.youtube.com/watch?v=EPWL-q6zwPo. Basically the tearing I'm seeing is seeking random triangular polygons attaching themselves to random objects all over the screen, clipping through everything. It's not a minor issue, it's quite seizure-inducing.

I decided to start digging, seeing what could be the problem.

My computer tests out fine in other games (tried Diablo 3, Skyrim, Bioshock Infinite, Path of Exile, and a few other games in my steam library) and stress tests like furmark and evga oc scanner.

Verified steam game cache, currently patch v1.2.37.0.0

Running clean install of gpu drivers 359.06, and tried a clean install of
358.91, the fallout 4 game ready driver from a few weeks back.

Air cooling, normal temperatures under load, no overclock.

Windows 10
i7 3930K
32gb ram
EVGA ACX 2.0 GTX 780 (recent RMA exchange)
Asus Sabertooth x79
Corsair RM650i power supply (brand new)
SoundBlaster XFi
Samsung EVO 850 SSD

I am at a loss as to whether it is my graphics card or a bug in the game itself.

I did try the game a month ago on release (as in not having the patches I do now thanks to steam), and didn't have these polygon tearing issues. HOWEVER at that time I did an rma for my graphics card as I was having stability issues. And crashing reliably during character creation was the last straw. That old card did crash during stress tests within seconds. The new replacement card doesn't show any signs of issues in anything I throw at the EXCEPT for fallout 4.

Looks like more of your card again but also can be insufficient power from power supply.

But this looks like what I had years ago,it was due to video card.

I doubt its a power related issue. The GTX 780 has a TDP of 250W (average use under 230W). Power supply recommendations err on the side of caution, and factors large power draw from other hardware components.

I would try other driver revisions, but it could still be a defective GPU.

The two major power draws on your systen are: The GPU (250W max) and the CPU (130W max).

I have ruled out a lack of power possibility by hooking up my 650 watt power supply to just the gpu and shorting pins 15 & 16 to power it on, then powering on the system with a spare 520 watt power supply. Same graphical issues.

You're right, they do err on the side of caution. I tried a second power supply anyway as mentioned above to no avail. as for drivers i've tried a few revisions, 359.06, 359.00, 358.91, 358.50, 355.60, and 353.30. all with no discernible change . I have also tried a different pcie slot just to see if maybe it was seated odd.

Since I have seen it elsewhere, ill post my dxdiag info here too.

I didn't catch that, thanks! Unfortunately after I freed up to ~20% free on C, the same artifacts occur. Also I disconnected my secondary storage drive as I've got the game installed to my SSD.

The only other thing I can say is clean out the dust inside the pc and also try reinstalling the video drivers.

Try play games with DX11 and see if still happens too.

Make sure you dont have your ram overclocked and cpu which also can lead to what happing in the video.

Also could be bad connection of your video card with the PCI,remove the video card and put it back carefully and fully inserted.

Don't overclock your card with the EVGA utility. !!!

Try a different resolution except your natives one. 1920x1200

Try Windowed - Borderless.

Disable AA and AF

Underclock your GPU.

Do you play with the VGA or DVI cable?

Also you have a lot of problem signatures on your Dxdiag.

I clean the dust of of my pc regularly, last time was just two months ago when i upgraded to 32GB of ram. I have ran memtest86 and detected no errors with the memory.

Since this issue, I have given a few other games/apps a shot, the free version of 3dmark, unigine heaven, Crysis 2, Civ V, Batham Arkham City Origins, and FEAR3. These apps were listed on wikipedia as having DX11 support. I ran them all at max settings. I also tried Witcher 3 and only had minimal polygon issues with the characters hairworks physics enabled, I normally run that disabled as its a huge drop in FPS.

RAM is not overclocked save for loading am XMP profile. I have tried it with XMP and SPD/auto. Otherwise, I don't overclock any component in my system.

I re-seated the GPU in another slot to test the connection and no change. Moved it back afterwards, as thermally its better for my system.

I've tried all manner of settings that the launcher offers, different presets from low to ultra, including minimal resolution in windowed borderless modes. AA&AF modes disabled.

Via the EVGA OC utility I under-clocked the card as much as I could and didn't notice a change in the issue.

I play with DVI to 2X DVI monitors (Dell 2707WFP). I have tried running just one monitor on the system too.

I am unfamiliar with diagnosing problem signatures in dxdiag, but If i could be pointed in the right direction id be more than happy to figure it out. I have since the start of this reinstalled windows 10 via the "Reset this PC/keep all personal files" and noticed no change in the above issue. I installed latest GPU drivers, sound drivers, and chipset drivers. This also includes a re-download of fallout 4 which properly verifies the file integrity via steam. I have the dxdiag from this install and am noticing a few different problem signatures, here is that report:

After this posting ill be diving deeper into motherboard drivers and trying to address the problem signatures I see in dxdiag. Thank you guys for your help so far , you've given me a few things to address which weren't immediately noticeable to me, despite so far hitting dead ends.

Missed a reply;

Yes, I have tried compatibility mode for fallout4.exe in the install folder via steam. No changes.

HID\VID_046D&PID_C07D&REV_8802&MI_01&Col03

This could be related to an Logitech Virtual gaming keyboard?

Have you the latest drivers installed from Logitech?

--------------

This bothers me at most !!!

Can you try a clean boot?

https://windowsinstructed.com/clean-boot-windows-windows/

---------------------

PnPRequestAdditionalSoftware

This could be ralated to any USB ports, USB root hubs, USB seetings in the BIOS (?!?)

Make sure that you update to the latest chipset drivers and your motherboards USB port drivers as well.

You shouldn't be getting any polygons on the witcher 3,this is sounding like your video card is the problem and not only for FO4.

You will have to RMA again,also your probably know this but make sure to disperse any static electricity you have before handling with the video card again.

I fried a video card like that before and it was showing signs of dying like in your video,next time I booted up it was dead.

Logitech virtual gaming keyboard... i'm assuming that relates to the mouse. Early on in troubleshooting I had the latest version. I don't see how that could affect it, but Id try it. Hadn't yet reinstalled em this round. But, to narrow that out i went ahead and disabled all usb ports and hubs in the bios as the fresh install of windows 10 had issues with my usb 2 ports. That is most likely what threw the PnPRequestAdditionalSoftware flag.

I just did the clean boot with no usb devices enabled (ps2 keyboard with mouse keys ftw!) and all non microsoft services disabled save for steam, as that needed to be ran in order to load Fallout. No change. Thanks for trying though

This is the dxdiag from this run of troubleshooting.

I am leaning towards video card too. Its just that this is the second RMA replacement I have received from EVGA (first replacement refused to install drivers and reverted to the basic ms display driver) and am trying to do as much homework as I can to back my claim. Aside from the slightly messed up (but obviously not correct) Geralt's hairworks in Witcher 3, I searched for another dx11 test I could do that does hairworks, figuring it may be a trigger even though its not utilized at all in fallout 4 to my knowledge. I can across a benchmark util called "Monster Hunter Online Benchmark" that had hairworks at parts. Sure enough, there was some minimal polygonal glitching going on in the background seemingly unrelated to the hairworks.

I'm gentle with hardware as I know static can be a sort of silent killer. I suppose its possible something got to it, I certainly didn't run around the carpet with shoes on before touching any hardware

Tomorrow I will try the card in another known good computer and see how it fares. If it still freaks out its definitely the card. If it was an issue with fallout unique to a 780, id expect at least one more post similar to mine.

Well, you said other games running fine, YES? - Hmm...that's a mystery.

> Tomorrow I will try the card in another known good computer and see how it fares. <

Yes, that's worth a try...

Also to try: take your GPU out, and put it in the second PCI-E expansion slot. You should have two of them.

He did do that some post above.

Yeah, missed that part obviously. lol
