◆ GetBackMemoryPoolSize()

static uint32 FWindowsPlatformMemory::GetBackMemoryPoolSize ( )

inlinestatic

Value determined by series of tests on Fortnite with limited process memory. 26MB sufficed to report all test crashes, using 32MB to have some slack. If this pool is too large, use the following values to determine proper size: 2MB pool allowed to report 78% of crashes. 6MB pool allowed to report 90% of crashes.
