Hell Let Loose: Vietnam Best Settings for Max FPS
Best settings for Hell Let Loose: Vietnam: tested graphics presets, DLSS and TSR tips, plus individual tweaks to boost FPS without losing visual quality.
What are the best settings for Hell Let Loose: Vietnam?
The best settings for Hell Let Loose: Vietnam start with the Master Quality preset at High or Medium, DLSS in DLAA mode on Nvidia cards (TSR at 100% resolution scale on anything else), FX Quality at Medium and Hardware Lumen at Low or Off. Those recommendations come from TroubleChute's post-launch benchmark pass, which tested every graphics option on the full release build. His headline finding: performance roughly doubled between the beta and launch, so the game is far friendlier to mid-range hardware than the early playtests suggested.
Graphics presets and upscaling
Master Quality is a single preset at the top of the image quality menu that drives every other option in useful steps. In testing, moving from Epic to Low took framerate from around 90 to 130 FPS without any upscaling. Upscaling choices are limited to FXAA, TSR and DLSS — there is no XeSS or AMD FSR — and running at least some anti-aliasing matters, because the game shows heavy aliasing with none.
- Nvidia cards: pick DLSS and set the mode to DLAA for the sharpest image at a small FPS cost; drop to Quality if you need frames back.
- Other GPUs: use TSR with resolution scale at 100% and anti-aliasing quality at Epic — it is the scale slider, not the AA setting, that changes performance.
- Avoid dropping below DLSS Quality, especially on 1080p and 1440p displays; the image degrades into blur and glitches quickly.
Recommended individual settings
| Setting | Recommendation | Notes |
|---|---|---|
| Master Quality | High (Medium for more FPS) | Biggest single lever; Epic to Low was ~90 to ~130 FPS in testing |
| Upscaling | DLSS + DLAA (Nvidia) or TSR at 100% | XeSS and FSR are not available |
| FX Quality | Medium | Epic to Low moved ~80 to ~100 FPS, most of it from High to Medium |
| Reflection Quality | Medium | Near-identical to Epic visually; ~78 to ~85 FPS from Epic to Medium |
| Hardware Lumen | Low or Off | Roughly 10% FPS from turning it off; far cheaper than in the beta |
| Post-Processing | High | Biggest jump is Epic to High; step down only if you need frames |
| SSAO | High or Off | Middle values add little; the gain sits between Low and Off |
| Motion Blur | Off | Small FPS gain and steadier target tracking |
| View Distance | High | No measurable FPS cost even with distant helicopter fights |
| Shadow Quality | High if possible | Low drops some object shadows; impact is small (possibly bugged) |
| Texture Quality | Max, if VRAM allows | Free visual quality; low VRAM causes stutter instead |
| Nvidia Reflex | On (On + Boost if CPU-bound) | Cuts input latency |
A few options barely matter on the current build: Landscape Quality, Shading Quality and Global Illumination showed little to no performance or visual difference in testing, so set them by taste. Film grain and Foliage Quality were removed entirely from the full release.
Quick wins outside the graphics menu
Update your GPU drivers first — Nvidia, AMD and Intel all shipped new drivers around launch. Console players have their own settings walkthroughs to follow, including dedicated PS5 guides that appeared on YouTube shortly after release.
