I believe I am dealing with a memory leak and I am on the verge of buying a different graphics card because I cannot do anything with these crashes.
Given enough time, usually a few minutes only, UE4 will freeze, the memory usage will spike, and then UE4 will crash. I have a brand new computer, AMD Oct-Core 4.7ghz, 32 gb RAM, Windows 8 and a Radeon R9 295x2 8gb graphics card. I even crash on a blank level with no starter content.
I have it open right now waiting for a crash report. It is idling at 345.6MB of memory usage.
BAM, it freezes, the Memory usage spiked to 2.3 GB and then it closed producing the below crash report.
Other things I have tried include using beta drivers, installing this on a SSD, creating a drive D to install. The D drive was a wild guess because the directories below don’t exist and are produced even if I don’t have a D drive.
Help is greatly appreciated, I have not been able to work on our simulation for almost 2 weeks now!
