The safest settings workflow for Hell Let Loose: Vietnam is a measured baseline, not a copied list of low values. Start at your display’s native resolution, use the game’s recommended preset, measure one repeatable scene, then lower one expensive option at a time. Compare only reconstruction modes your hardware and current menu support, and measure the base frame rate with Frame Generation off before testing it.
- Missing options or startup crashes
- Low FPS, stutter or rubber-banding
- GPU feature support
- Settings do not save
Hotfix 1.5.2: reset PC video settings
Hotfix 1.5.2 is live and adds AMD FSR 4.1 support alongside updates to stability, VOIP, memory use and server replication. The developer recommends that PC players using AMD or NVIDIA GPUs reset Video Settings to default after the update so the game can recalibrate settings for FSR 4.1.
Before resetting, record or screenshot your current values. Then start from the default settings and change one option at a time. The reset is an official troubleshooting recommendation; it is not a promise of a specific frame rate.
- FSR 4.1 is available for AMD Radeon RX 7000 Series GPUs and newer, according to the developer. The developer says RX 6000 Series support is planned for 2027.
- NVIDIA users should reset their Video Settings as advised, but FSR 4.1 itself is an AMD feature. Use DLSS or TSR only when the current game menu offers it for your hardware.
- After the reset, record the build, GPU, driver, resolution and a repeatable test scene before comparing changes.

DLSS options missing after a patch: check the menu before tuning FPS
A missing quality selector and low frame rate need different tests. First identify whether the option is absent, the image is unstable, or the game crashes. Avoid changing the whole preset while investigating one missing control.
In Community Feedback #7, October 9, the developer reports a startup timing issue that can hide DLSS quality choices even while DLSS remains active; reapplying settings may reveal the choices. At that October 9 snapshot, a potential fix was undergoing validation. Reports should include GPU model and available VRAM. This is not confirmation that every missing DLSS or Frame Generation option has the same cause.
A controlled menu check
- Record the game build, GPU model, driver version and available VRAM. Screenshot the Video Settings menu before changing it, including any missing or disabled controls.
- After an update, let shader caching and the initial loading screens finish. Hotfix 1.5.2 guidance warns that continuing during caching may cause crashes. Record whether the symptom occurs during startup or after reaching a match.
- For the missing DLSS quality selector, try reapplying the current settings, then check the selector again. Screenshot the result. This tests the developer-described menu behavior; it does not establish an FPS improvement.
- If using the official post-update default reset advice above, save your old values first. Treat reset as a separate test: record which options return, then restore preferred settings one at a time. Do not combine reset, a driver change and a preset change in one comparison.
- Once the menu behaves consistently, repeat the same scene with Frame Generation off if that control is available. If it is absent, record that state and leave it unchanged. Then compare one reconstruction choice that the menu actually offers. Record input feel and image stability as well as FPS.
- If the control remains absent or crashes continue, stop the tuning loop and send the before/after menu captures and hardware details to Team17 support. Do not infer eligibility from the option name alone or edit hidden configuration files to force it on.
Which symptom should you investigate?
| Symptom | Next check | Useful evidence |
|---|---|---|
| DLSS quality choices are absent | Reapply settings and compare the menu | Before/after captures; GPU and available VRAM |
| Frame Generation is absent | Record the exact menu state and hardware; report separately | Disabled versus missing control; build and driver |
| Crashes during first post-update launch | Allow caching/loading to complete; record the failure stage | Error text, time and whether a match was reached |
| Foliage pops in or cover disappears | Capture the same location and camera movement | Map, location and video; avoid unsupported engine tweaks |
Patch 1.7 was released on October 21. Check the October 21 Patch 1.7 changelog for the published platform-specific changes; the October 9 preview is historical. Console display features do not establish PC support or a measured improvement on your hardware. If stable FPS accompanies rubber-banding or missing spawn points, continue with the server and connection checks instead of lowering graphics blindly.
Copyable comparison record
Build / date: GPU / driver / available VRAM: Symptom and startup stage: Before menu screenshot: One action tried: After menu screenshot: Same-scene FPS / input feel: Result: improved / unchanged / worse / not tested
This is an editorial diagnostic workflow, not a measured benchmark. We have not tested the menu workaround or performance gains on a current game build.
Fast release-build baseline
Use this safe starting workflow:
- Update the GPU driver and restart the PC.
- Use your monitor’s native resolution and a normal graphics preset.
- Disable overlays and recording tools only for the first diagnostic run.
- Record average FPS, frame-time behavior and input feel in one repeatable scene.
- If GPU usage is consistently high, test one lower quality option or an image-reconstruction mode.
- If FPS drops only on a crowded server or during heavy action, test another server and time of day before blaming a graphics setting.
- Keep the change only if it improves the same test without making visibility or input feel unacceptable.
The Steam requirements checked October 20, 2026 target 1080p/60 fps in both tiers. The minimum note uses TSR at 71% or DLSS Ultra Performance; the recommended note uses TSR at 100% High or DLSS Balanced. These are published targets under different reconstruction settings, not measured results from this site or a 1440p guarantee. Check the dated Hell Let Loose: Vietnam system requirements before comparing results.
Measure before changing settings
A useful settings test controls the variables that can otherwise mislead you. Record:
| Test field | What to write down | Why it matters |
|---|---|---|
| Game build | Version or test date | Performance can change between beta, playtest and launch |
| CPU and GPU | Exact models | The same preset can hit different bottlenecks |
| RAM | Capacity and configuration | Helps diagnose memory pressure without inventing a requirement |
| Resolution | Output resolution and scaling mode | A major part of GPU workload and image clarity |
| Map and location | A repeatable route or viewpoint | Dense vegetation and elevation can change the load |
| Server | Name, region and player count | Server load and latency can resemble local stutter |
| FPS evidence | Average, low points and frame-time graph if available | Averages alone hide spikes |
| Input feel | Smooth, delayed or inconsistent | Frame Generation can raise displayed FPS without fixing the base response |
Run the same route for long enough to include movement, foliage and a view across terrain. Do not compare an empty menu with a 100-player battle.
Is the problem GPU, CPU, server or network?
The developer’s July performance update says open-beta limits were found across the GPU, CPU and server, and that different players were affected differently. Animation smoothness, movement, voice quality and input response could also be influenced by client or server performance.
Use symptoms to choose the next test:
| Symptom | Possible constraint | Next useful test |
|---|---|---|
| GPU usage remains near its limit and FPS changes with resolution | GPU or rendering load | Lower resolution scale or one visual option |
| FPS barely changes when resolution is reduced | CPU, server or another non-GPU limit | Compare a quiet scene and another server |
| Rubber-banding while local FPS remains stable | Network or server | Check latency, packet loss and a second server |
| Long spikes during traversal | Streaming, shader, driver or background activity | Repeat the route after restart and close background tasks |
| High displayed FPS but delayed controls | Weak base frame rate or Frame Generation latency | Disable Frame Generation and compare input response |
| Settings revert after restart | Configuration persistence | Apply one obvious change, restart and verify it saved |
These are diagnostic signals, not proof. Change one variable and reproduce the result before deciding.
Three safe profile frameworks
The following profiles are testing frameworks, not final numeric presets.
Performance profile
When the diagnostic points to GPU load, start from a lower preset and compare one supported reconstruction mode. Keep Frame Generation off while judging base response; protect foliage clarity.
Balanced profile
Start from the recommended preset, then use the measurement sheet to keep only changes that improve repeatable frame time without harming terrain readability.
Visual profile
With headroom established, increase one feature at a time. Test Hardware Lumen separately and include dense foliage and active combat in the comparison.
TSR, DLSS, FSR and Frame Generation
Reconstruction changes how the image is rendered and rebuilt. Frame Generation inserts frames between rendered frames. One feature appearing in the menu does not prove support for the other.
| Feature | Published support / purpose | First check |
|---|---|---|
| TSR reconstruction | The existing performance guidance describes TSR as an image-reconstruction option. | Use an offered mode; compare image clarity and frame time with your baseline. |
| DLSS reconstruction | The dated performance guidance covers supported NVIDIA hardware. A quality-selector fault is separate from GPU eligibility. | If choices disappear, use the controlled menu check. |
| FSR 4.1 reconstruction | Hotfix 1.5.2 describes support for AMD Radeon RX 7000 Series and newer; RX 6000 support was a 2027 plan. | Keep this reconstruction requirement separate from AMD Frame Generation. |
| NVIDIA Frame Generation | The performance guidance describes supported GeForce RTX 40-series and newer. | Measure response with the feature off first; generated FPS does not measure base response. |
| AMD FSR Frame Generation | Patch 1.7 names supported AMD GPUs, 5000 series and above. This is a graphics-card scope, not a CPU requirement. | Check Video Settings on supported hardware; compare base FPS and input feel before enabling it. |
The October 21 Patch 1.7 announcement recommends a base rate around 60 FPS or higher before Frame Generation, particularly for high-refresh displays; lower base rates can increase latency. That recommendation is not a benchmark for your PC.
- Record the same scene with Frame Generation off.
- Compare one offered reconstruction mode, watching foliage, motion and text.
- Only then test supported Frame Generation, keeping the scene and other settings unchanged.
- Keep it only if the image and input response remain acceptable; report a missing control separately from low FPS.
Hardware Lumen
Hardware Lumen provides hardware-accelerated lighting and shadows. The developer positions it as an optional enhancement for high-end PCs with performance headroom.
If performance is the goal, test with Hardware Lumen disabled first. If the balanced baseline is already stable, turn it on alone and compare:
- GPU utilization and power;
- average frame rate and frame-time spikes;
- dark interior visibility;
- foliage and shadow stability;
- input feel during combat.
There is no universal competitive answer without repeatable current-build testing. A brighter or flatter image is not automatically more accurate, and maximum lighting quality is not automatically better for play.
Visibility-sensitive settings
Visibility in a dense jungle is more than raw resolution. In the current Video Settings menu, compare options affecting:
- anti-aliasing and reconstruction stability;
- foliage and view distance;
- shadows and global illumination;
- post-processing, blur and depth effects;
- texture clarity and filtering;
- sharpening.
The goal is a readable, stable image in motion. Extreme low settings can create shimmer or unstable edges that make movement harder to identify. Extreme sharpening can add halos. Compare stillness, panning and fast movement.
The July developer Q&A says optic aiming uses depth of field to focus attention. Treat the visual effect as version-sensitive and verify it in the current game before recommending a specific value.
Troubleshoot stutter in this order
- Record the installed game and driver versions, then complete startup caching before testing.
- Repeat one route with your baseline. If testing overlays or background programs, close them for a separate run and note exactly what changed.
- Use the symptom table to choose a rendering or server test. Stable local FPS with rubber-banding needs a connection check.
- Retain only a repeatable improvement. If stutter persists, send build, hardware, scene, server and reproduction steps to support.
Steam’s October 20 requirements list 30 GB available space, without an explicit SSD requirement. Allow installation and update headroom. Avoid hidden launch commands or deleting configuration files as an unexplained first step.
If settings do not save
The official July performance blog says some open-beta players saw defaults that did not suit their hardware, settings that did not apply correctly, or settings that did not save reliably. The developer reported improvements ahead of the next playtest.
If settings do not persist after a patch:
- Change one obvious option.
- Apply it and return to the menu.
- Restart the game and check the value.
- If it reverted, record the build, Windows account permissions and whether cloud synchronization is involved.
- Use the official support route before editing files manually.
This section describes a beta-era issue and a verification workflow. It does not claim the problem exists in the current build.
What not to change blindly
- Do not lower every setting at once.
- Do not compare different maps, servers and resolutions as if they were one benchmark.
- Do not enable Frame Generation to hide an unstable base frame rate.
- Do not call network rubber-banding a GPU problem without testing.
- Do not copy hidden engine-file tweaks without knowing how to restore the file.
- Do not trade away a stable image for an impressive average FPS number.
Release-build benchmark sheet
Use the measurement fields above for your own comparison. Add the preset, reconstruction mode, Frame Generation and Hardware Lumen state so another run can repeat the same conditions.
Until that evidence exists, use the worksheet above to create a result that can be repeated. If voice, connection or server symptoms are mixed with FPS problems, use the servers, crossplay and voice chat guide.
