2.0 GB minimum (higher recommended for 64-bit stability).
The release of version 4 was a watershed moment for the platform. For years, the simulation community was constrained by 32-bit architecture, which limited memory access to 4GB. This often resulted in "Out of Memory" (OOM) errors during complex scenarios involving high-resolution textures and dense environments. The transition to a in P3D v4 fundamentally changed the landscape, allowing the software to utilize nearly unlimited system RAM. This technical leap enabled the creation of incredibly detailed global environments and more stable long-duration training sessions, which are critical for professional certification.
