Hell Let Loose: Vietnam DLSS 4.5 Settings Guide
Patch 1.4 adds DLSS 4.5 and 5x/6x Frame Generation options for supported NVIDIA 50-series GPUs. Use this page to verify eligibility and compare the changes without assuming a fixed FPS gain.
Patch 1.4 adds DLSS 4.5 and 5x/6x Frame Generation options for supported NVIDIA 50-series GPUs. The update does not promise a fixed FPS gain: confirm that the options appear, stabilize the underlying frame rate, then compare one change at a time for clarity, smoothness and input response.
What Patch 1.4 adds
The Patch 1.4 notes list DLSS 4.5 and 5x/6x Frame Generation among the new PC rendering options. These are separate ideas: DLSS changes how the game reconstructs the rendered image, while Frame Generation creates additional displayed frames between traditionally rendered frames.
| Option | What to check | What it does not prove |
|---|---|---|
| DLSS 4.5 | Whether the current PC menu exposes the updated DLSS option | That every GPU receives the same choices or image quality |
| 5x Frame Generation | Whether the option is available on a supported NVIDIA 50-series GPU | That the underlying game simulation is running five times faster |
| 6x Frame Generation | Whether the option is available and responsive in the current build | That it is the best choice for every map, resolution or player |
The safest interpretation is that Patch 1.4 gives eligible PCs more rendering choices. It is not a universal performance preset, and this page does not claim a fixed frame-rate improvement.
Who should see these settings?
The patch notes identify the new DLSS and 5x/6x Frame Generation support for NVIDIA 50-series GPUs. This page therefore targets the PC graphics menu on supported NVIDIA hardware; it is not a guide to console graphics settings.
If you use an AMD GPU or an older NVIDIA card, do not treat a missing DLSS 4.5 or 5x/6x option as proof that the game is broken. Start with the official system requirements guide and the broader best PC settings guide instead.
A safe setup order after the update
- Let the game finish updating, restart it and confirm that you are testing the current Patch 1.4 build.
- Record your resolution, current upscaling mode, Hardware Lumen state and any existing Frame Generation setting.
- Confirm that the DLSS 4.5 and 5x/6x choices actually appear in the PC graphics menu. Do not infer support from the GPU brand alone.
- Stabilize the base frame rate with Frame Generation off. A generated-frame setting cannot remove a CPU, memory, server or network bottleneck.
- Enable DLSS 4.5 and compare the same resolution, map, scene and visual target. Look at image detail and frame pacing, not only the counter.
- If the result is stable, test 5x and 6x separately. Compare camera movement, input response, ghosting and distracting artefacts before keeping either option.
- Keep the change only if it feels better. If not, revert the last setting and test the next one rather than changing the whole preset at once.
The existing best PC settings guide explains why Frame Generation should be tested after the base result is stable. Its baseline remains useful; this page only adds the Patch 1.4-specific decision points.
If an option is missing or feels worse
| Symptom | First checks | Safe next step |
|---|---|---|
| DLSS 4.5 is not listed | GPU eligibility, completed game update and a full restart | Use the current TSR/DLSS choices documented in the PC settings guide |
| 5x or 6x is not listed | Confirm that the GPU is an NVIDIA 50-series model and that the client is on Patch 1.4 | Do not force a setting through an unofficial tweak; test the supported baseline instead |
| The image looks unstable | Compare the same scene with the previous upscaling mode and inspect fine detail while moving | Revert one option, then try a less aggressive choice if the menu provides one |
| It looks smoother but feels delayed | Compare input response with Frame Generation off at the same base settings | Keep the base frame-rate improvement and leave Frame Generation disabled if responsiveness is worse |
| FPS does not improve | Check whether the limit is CPU, memory, server or network behavior rather than rendering | Use the crashing and performance checklist and record the exact test conditions |
Patch 1.4 also contains fixes for controls, spawning, tunnels, markers, audio and maps. If the problem is not specifically a graphics-option problem, use the full Patch 1.4 notes to choose the more relevant troubleshooting path.
Quick answers
Does Patch 1.4 guarantee more FPS?
No. It adds new rendering options, but the result depends on hardware, resolution, scene, settings and other system limits. Treat the official patch note as a feature update, not a benchmark promise.
Should every supported PC use 6x Frame Generation?
No universal setting is verified here. Compare 5x and 6x under the same conditions, then keep the one that preserves acceptable image quality and input response—or leave Frame Generation off.
Does this page replace the general settings guide?
No. Use the general PC settings guide for the official baseline and Hardware Lumen order. Use this page when you are specifically checking the Patch 1.4 DLSS 4.5 and Frame Generation changes.
