I am facing a very annoying problem when using the UE4.
I can open EU 4.18 normally and I can use Crash for a few seconds.
I put the editor to run in Unlit and it lowers the graph of the editor to Low (thinking that it could solve), but the problem of crash persists.
I have the following PC configuration:
Notebook: Inspiron 5547
OS: Windows 10 64-bit
Memory: 8 GB DDR3
Processor: i7-4510U CPU @ 2.00GHz
Video Card: AMD Radeon R7 M260
I added the UE4Editor and UE4Game EU files in the AMD Radeon Settings game panel and I am running the notebook in high performance.
I tried to change the response time of the video card as I saw it on the internet (through regedit creating the TdrDelay file) but it did not work (I believe this only works for nVidia cards). I also disabled the Real-Time Thumbnails in the editor and even then the problem persists.
I installed the UE4 diagnostic service and this is the error that appears:

I could not find other solutions. I am going through this topic to try something else to solve this problem or if the notebook does not actually run the UE4, I will eventually get a desktop of satisfactory configuration to use in dev.
Thanks any help
