Hello, I have been using unreal for a while, and since using 4.8, I haven not been able to open material editor and use texture node specifically. I can use vectors, lerps and anything else like that. But as soon as I add a texture node, it crashes. I have a GTX 760 4GB, Intel i5-4690k 3.5ghz, 16GB ram… ---

Hi Piplington, Please copy information in Crash Reporter window when this crash occurs, including Machine ID, and paste it here (and be sure to hit Send!). Then and attach crash log from project’s Saved\Logs folder. It may also be helpful to see your full dxdiag. Thanks! ---

No crash report unfortunately. Just “Unreal Has Stopped Working” thanks for reply! I hope this can be sorted. ---

Hi Piplington - windows error that you are experiencing is being caused by an out of date Intel Integrated Graphics Driver ( igusc64.dll). With some of new additions to our Post Process and other improved Rendering pathways in 4.8, these older drivers are not able to handle newer information. So to fix that problem, you will need to download and install latest Intel Driver that can be found here: > **[Download Intel Drivers and Software](https://www.intel.com/content/www/us/en/download-center/home.html)** > > Download new and previously released drivers including support software, bios, utilities, firmware and patches for Intel products. Now you list that you have an Nvidia GTX 760, if you are running on a laptop then another problem exists as well. Your Nvidia Optimus program which handles switching for power saving purposes is not seeing Unreal as needing Nvidia card and defaults to using Intel card for power saving purposes. You will need to go into Optimus program and set UnrealEngine.exe to always use Maximum Performance and Nvidia card. Thank you Eric Ketchum ---

thank you! im on a Desktop PC though, not using a laptop, is there still a problem with software not using my graphics card? ---

It might be, can you include a copy of your DXDIAG? ---

link text Im using a TV at my 2nd monitor. as I wanted another one, but only had enough money for PC and a monitor. I see no mention of my Nvidia GTX 760 all drivers are up to date, but now that you mention it, I cant open Nvidia Control Panel. All drivers are up to date this time for sure. I can use Nvidia Geforce Experience. ---

Hi Piplington - Ok so what I am seeing in DXDIAG is that your BenQ monitor is connected only to an Intel Integrated Graphics card (which needs to be updated per link above) and no mention of Nvidia Card. There appears to be a problem with your Nvidia Card, make sure that card is showing up in your Device Manager without any warnings or errors and that you monitor is plugged into that card. In any event, downloading link above will keep Engine crashing Intel Card until you can debug Video Card itself. Thank You Eric Ketchum ---

I have updated driver, and unreal no longer crashes. Though I would obviously like to use my GTX 760. I will keep trying what you say, thanks for help so far!!
