Hell Let Loose: Vietnam moves the series from Unreal Engine 4 to Unreal Engine 5, and its requirements are noticeably higher than its predecessor's. Much of that comes down to environment density: Nanite virtualised geometry renders large volumes of individually modelled jungle vegetation across 100-player maps, which is demanding in the thicker terrain the Vietnam setting calls for.

Both the minimum and recommended specs assume upscaling rather than native rendering — DLSS or TSR is expected to be enabled to hit the stated performance targets, so hardware matching the minimum spec will fall short of it at native resolution.
