UE4 Editor is causing my video card to frequently reset (and thus crash the editor as well).
I initially thought the problem was my video card (Radeon 285), but two things happened…
First: I bought a new card (Radeon 390) and gave the Radeon 285 to my brother. The video card crashes persisted even with the new card, but didn’t happen on my brother’s computer. At the moment, I had a 4K monitor and my brother, a FullHD monitor.
Second: Then my brother bought a 4K monitor and he started getting the crashes as well.
The video card crashes seem to happen only when I’m using UE4, and only on Medium or higher scalability settings. It has not crashed yet while using Low settings. Crashes happen even on a template project.
I have played Metro 2033 Redux and Total War Rome 2 for many hours (both at 4K) and have not experienced a single video card reset with either game. So I don’t think the problem is with either card (i.e. the hardware).
I am running Windows 10, and tried both Catalyst 15.7.1 and 15.8 beta.
It crashes anytime: navigating the map, editing materials, editing blueprints, etc. If I deactivate Real Time however, or set quality settings to Low, I can edit blueprints just fine without a crash.
Also, it seems to depend on scene complexity. It can take a long while (or very quickly, sometimes) to crash on simple or template maps. But if I open a more complex map, it crashes in less than 1 minute.
Right now, I tried a complex map on several resolutions, with Real Time activated and on Epic quality settings, results:
At 4k, it crashed in less than 1 minute. Tried 3 times.
At 2560x1440, it crashed after about 2 minutes. Tried once.
At 1920x1080, it crashed after about 5 minutes. Tried once.
I’m confused now. Could it be something specific to this monitor or DisplayPort? It’s a Samsung U28D590, connected via DisplayPort 1.2. I’ll try connecting via HDMI and update.
When a video crash occurs, does it saves a log somewhere that could help debug this?
I have been getting hard freezing (like i gotta restart computer) with a similar setup.
Using UE 4.8.3
amd 390,
4k display.
Time doesn’t really seem to matter. It’s random crashing. fine with all the other software I’ve used so i know its this program.
I can’t reproduce this at my schools computers either so I know it’s my setup on UE4
I went back to 4k resolution, and noticed something. It only crashes when I move the camera. I managed to let it run for like 40 minutes (with Real Time activated) and edit blueprints without a problem. But soon as I move the camera, the video crashes within 1 to 20 seconds (observed this behavior 4 times in a row).
Same thing happens in Play in Editor (new window), and Standalone Game.
I’ll try now setting each scalability setting group individually from Low to Epic to narrow down the problem.
Well I think I found out something! It doesn’t seems to crash when Shadow quality is set to Low (and everything else to Epic). I’ll keep trying this, and also on my brother’s computer.
Khaldanis, please try this as well and let us know if it crashes for you this way.
I didn’t customize anything, I just left the fan speed on Auto. No overclock, either.
I just ran a test and it crashed when the card was at 72° C (after about 2 minutes running a camera Matinee I created for testing, on a relatively simple map).
I am going to attempt our tests again, but try some more projects and let it run longer. I apologize for any delay as I was trying to track down a 4k monitor to use again, but I’m going to go ahead and run on 1080p.
I know it can’t be heat related because my card runs anything else full blast for hours. Over the 4 projects I’ve run they all crash but not doing the same thing or at the same time.
amd 390, driver 15.7.1 (latest but not “beta”)
The program will even crash my system when minimized (only happened once maybe i should test it?)
I tried Unreal Tournament now and also got video card crashes. Except this time they aren’t random.
It ALWAYS crashes when I try to play in either CTF-Face or Outpost 23 (by going through Offline Action, if it makes a difference). This happened 8 times in a row.
The moment it crashes is on that screen that shows which characters are in the match, just before starting the match (it crashes when the characters are still on screen, when the game is about to start). I can roam around the map (before pressing the mouse button to start) without a crash.
For whatever reason, CTF in Titan Pass works normally (doesn’t crashes after showing the characters, tried it 4 times and no crashes).
I didn’t try the other maps, but if it could help in debugging, I can try. (Just tried Deck16, it also crashed).
I’ll experiment with different graphics settings and update.
Well I first switched from Windowed Fullscreen to Fullscreen. Tested it on Outpost23 and it worked. I thought “Hey so that’s the problem!”, so I switch back to Windowed Fullscreen, restarted the game (just to be sure), started a new match on Outpost 23, and it’s no longer crashing. Neither is it crashing on Face or Deck16.
Update - I’ve built from source (master branch, 4.11) and ran some tests.
The random crashes are still happening.
Running with -dx12 still causes the video card to crash when it is about to open the editor.
Now here’s the news: I had been running the editor (4.9) on Low settings (because of the crashes), and tried to open it in Dx12 mode again to check if it was the same crash as on 4.11. To my surprise it opened normally without crashing.
It turns out that what causes the VGA crash in dx12 mode is setting Anti-Aliasing to High or Epic. While on DX12 mode, if I just click “High” on Anti-aliasing, I instantly get “VGA stopped responding and had to reset”.
However, setting Anti-aliasing to Medium, and everything else to Epic, works normally on dx12 mode.
In this DX12 mode (all on Epic except AA) I haven’t experienced a crash yet in 10 minutes; I’ll keep trying it and update.
