Bizarre display driver problems when loading the editor.

Development Rendering

Okay, so I have no idea when this started to happen or why, but when I first was using Unreal Engine everything was fine; framerate in some levels was less than stellar but my harddrive was due for a reformatting. Anyway, after about a week or two, there were some strange green flickers every so often in my display. I thought that was just a bug with the rendering that would be patched up soon enough. But unfortunately that never happened, and now Unreal Engine has gotten to an unuseable state. To show what I mean, I recorded a video with my phone:

As illustrated in the video, I enter the map, do absolutely nothing, and the graphics expodentially start to eat themselves until the entire editor just breaks down and my display driver kicks the bucket. Let it be known this didn’t happen initially when using UE4; this only happened within the last week.

I’m wondering if anyone has any idea what could be causing this, or how I can get to the source of the problem. Thanks!

Lastly, for reference, my specs are as follows:

GPU: NVidia 660 GTX

CPU: Intel i7 (pre-sandybridge}

RAM: 3 2GB Kingston cards (6GB total… probably not enough? Should be}

Ugh. I thought I set it to unlisted! Fixed that now. Thank you!

  1. Have you tried an older driver? (Preferably do a clean install)
  2. Who is the card manufacturer (e.g. EVGA) and are you using manufacturer provided utilities or drivers e.g. EVGA precision?
  3. Are you using experimental tools like nvidia Inspector?
  4. Have you overclocked the card?
  5. Is your card running too hot?
  6. What is your mainboard (motherboard)?
  7. What is your power supply wattage?
  8. Does the driver crash at a very specific point while using the engine?
  9. Do you experience these crashes anywhere else?
  10. Can you plug your graphics card into another PCI-e slot and try again?

I know I don’t have a definitive answer, but once this is known, we can check logs next.

Cheers!

Wow, I’m surprised you responded so fast!

I’m not too familiar with most of the answers to this but I’ll do my best.

  1. I don’t believe I have; that might help? But I wouldn’t know where to get a driver that won’t break everything haha.
  2. I do believe it’s EVGA, but I downloaded the drivers from nVIDIA’s website. which… might explain a few things honestly :I
  3. I do not believe I’m using Inspector.
  4. No
  5. No
  6. It’s an ASUS motherboard, forgot the version ^^;
  7. Not on hand at the moment :x
  8. Not at any point specifically; it usually happens when I stand still and let the graphics just crap themselves. It takes longer to break when I’m moving around, strangely…
  9. No. Unreal Engine 4 is the only thing to cause this; sometimes if I have UE4 open as well as Internet Explorer, internet Explorer could crash, but this hasn’t happened since my reinstall (my drivers were a bit corrupt back then, hence reformatting my computer. Fresh install of the latest drivers fixed the IE problem but not the UE4 problem)
  10. I might; I can’t do that this very moment though.

I unfortunately had to go to class and won’t be back in my room until 7:30 EST. But when I’m back I’ll leave a comment clearing up what I wasn’t able to cover just now.

Thank you!
