**Enviroment: **online game (32x) OS: win10 DX:dx9
CrashReport (from dump) : run out of virtual memory
Since many of our user’s OS upgraded from win7 to win10 and new art-resources imported to the game, the crash occured to our udk based project.
Many users reported after running a few hours , their gameclient will get crashed at random point.
We get the error D3DERR_OUTOFVIDEOMEMORY after get the return of VerifyD3d9Result,but acturally the user has more memeory avaliable.Sometimes it will happen at the usage of about 2 GB, and sometimes it will be near 3 GB usage.
We happened to decrease some of our texture size from 1024x1024 to 512x512 and the problem disppear for a month,but after importing some new resources(also 512x512) to the game, this crash reoccured .
We doubts the problem may be the support for dx9 by win10 or the resource limitation of udk.
Is there any instruction about this kind of crash problem?
