Hell Let Loose Vietnam Settings Guide
Officially described PC graphics options for Hell Let Loose: Vietnam, including image reconstruction, Frame Generation, and Hardware Lumen.
Hell Let Loose: Vietnam offers PC graphics options intended to balance image quality and performance. Start from the official capabilities, then test one change at a time on your own hardware.
Published graphics options
The official performance update names TSR and DLSS as image reconstruction technologies for supported hardware. It says NVIDIA GeForce RTX 40 Series and newer hardware can use Frame Generation, while Hardware Lumen is an optional high-end lighting feature.
Practical baseline
Frame Generation works best when the base frame rate is already stable, because it can add input latency at low frame rates. Treat any community preset as a starting point, record your hardware and resolution, and re-check after patches.
