Prior to the release of Prepar3D v4, flight simulators were heavily restricted by a 32-bit architecture. This limited the software to a maximum of 4 Gigabytes (GB) of Virtual Address Space (VAS). For professional applications requiring ultra-high-resolution terrain, complex weapon systems, and dense artificial intelligence (AI) traffic, this restriction frequently resulted in "Out of Memory" (OOM) crashes.
