NVIDIA Driver Crash in 4.3

Development Programming & Scripting
1

Running ue4 version 4.3 causes a driver error.

My specs are

Windows 7 64 bit

GeForce GT 520 Verto Video Card - 1GB, DDR3, PCI-Express 2.0 (x16)

AMD FD8150FRGUBOX FX-8150 Processor - Eight Core

12 gigs of RAM

Which driver do you have currently? If it is beta revert it to the previous stable version.
Also when is it crashing? When you try to launch the editor or while working in the editor?

When launching, 4.2 works just not 4.3

I’m having the same problem. Crashes on “Running engine benchmark.”

Graphics Card: GeForce GT 420M

Howdy and rob422lou,

There been a couple of other users that seem to have the same issues that you have possibly been running into. Here is a link to the other thread that may be able to help with a workaround: Disable Scalability? - Platform & Builds - Epic Developer Community Forums

Also rob422lou,

Could you provide your Dxdiag as well?

Thanks and have a great day!

Absolutely.

Howdy

Thank you for the Bug Report. I have been looking into the issue and have found what could be causing the issue with 4.3. Here is a list of both GPU’s that you both have provided and what is the recommended:

: PassMark - GeForce GT 520 - Price performance comparison

rob422lou: http://www.videocardbenchmark.net/gpu.php?gpu=GeForce+GT+420M

Recommended: http://www.videocardbenchmark.net/gpu.php?gpu=GeForce+GTX+470

By comparing the GPU’s listed and the recommended, you can see the GPUs are well below what is recommended. With the 4.3 update, there was a large update for graphic optimization, which could of caused the cards to work in 4,2 and not in 4.3. I would recommend an upgrade with your GPU as that should fix the error that you are seeing. You can use the link for the recommended to compare cards around the GTX 470 and see what possible options are available if you wish.

If any other information is needed, please feel free to let me know. Thanks and have a great day!

I found a workaround, . If you put the following into your BaseEditorGameAgnostic.ini it will work perfectly.

[EngineBenchmarkResult]
Valid=true
ResolutionQuality=100
ViewDistanceQuality=1
AntiAliasingQuality=1
ShadowQuality=1
PostProcessQuality=1
TextureQuality=1
EffectsQuality=1

Thanks for that workaround rob422lou. This has helped another user that had the same issue. It will help to lower the quality of the Engine so that cards that have been lower then the recommended run the editor.

If it helps I traced the problem. While running the engine initially runs the benchmarks my video card crashes once it reaches this part in SceneFilterRendering.cpp, in the DrawRectangle function:

if (Flags == EDRF_UseTriangleOptimization)
{
RHICmdList.DrawIndexedPrimitive(
GScreenRectangleIndexBuffer.IndexBufferRHI,
PT_TriangleList,
/BaseVertexIndex=/ 0,
/MinIndex=/ 0,
/NumVertices=/ 3,
/StartIndex=/ 6,
/NumPrimitives=/ 1,
/NumInstances=/ 1
);
}
else
{
RHICmdList.DrawIndexedPrimitive(
GScreenRectangleIndexBuffer.IndexBufferRHI,
PT_TriangleList,
/BaseVertexIndex=/ 0,
/MinIndex=/ 0,
/NumVertices=/ 4,
/StartIndex=/ 0,
/NumPrimitives=/ 2,
/NumInstances=/ 1
);
}

Thanks for that rob224lou! I have talked to a couple of other Devs and this issue should be fixed in a future release.

Have a great day!

Hey,

My display driver has been crashing as well, and I have a GTX 670 which should run the engine no problem. Since I un-subbed after 4.1 released, I figured the crashing was happening because I was running an old build. Just re-subbed and upgraded to 4.3 and it’s still crashing. Not doing anything in particular that’s causing the crashing either. I can just have it running in the background and it will crash.

I’ve checked my temps, everything seems normal there. I get display driver crashes occasionally, but I almost get it hourly in UE4.

Howdy Megamanslazar,

Thank you for reporting the issue that you have been seeing. Would you mind creating a new AnswerHub question for the issue so that we would be able to better investigate the issue. If you could also provide your DXdiag and any log files generated from the crash, it would be greatly appreciated.

Also, have you tried the workaround provided above by rob422lou?

Thanks and have a great day!

Hi
I also have a graphics card crashing issue (NVidia GT 630M). I’d like to try this BasicEditorGameAgnostic workaround but that file doesn’t exist at all on my hardrive (UE4.14). Any other options?
