When I try to build scene,my graphics card crashes…
My system;
Radeon software - 15.12 (latest driver)
AMD Radeon ™ R9 380 Series 4096 MB GDDR5 1010(gpu clock) MHz
Windows 10
System memory- 8 GB
CPU - Intel(R) Core™ i5-6500 CPU @ 3.20GHz
To ask the most obvious question, are the drivers up to date, as suggested? Is there an error log that you could provide?
Yes,I updated my drivers today.
I haven’t any error log(when gpu crashes,ue4editor.exe closes itself) but now,there isn’t any problems or crashes(I did not anything 
).
Thanks for your support,and sorry for my english
No problem, your English is perfectly understandable. I’m happy to hear the problem has resolved itself!
