Tags: , , ,

Continuing the series, today we look specifically at “overflow” allocations in the Temp allocator. We’ve seen that there’s no need to explicitly deallocate Temp memory because it all gets cleared every frame, but do we need to deallocate “overflow” allocations that didn’t fit inside the block of automatically-cleared memory?
