Metal Gear Solid Delta has no Lumen switch and no frame generation option in its menu, so the settings that actually move your frame rate are fewer than most guides imply: the Graphics Quality preset, Global Illumination, upscaling and the 60 FPS cap. Dropping Graphics Quality from Ultra to High bought 13–24% more FPS in three independent measurements, and TechPowerUp’s screenshots show High and Ultra looking nearly identical. Everything below was measured on the launch build; I found no outlet that re-tested after Patch 1.2.4, which is still the newest patch on Steam as of 14 October 2026. For the driver, Windows and monitor settings that apply to every game, start with our guide to optimizing PC game settings for better FPS.
Verified against Konami’s Steam patch notes through version 1.2.4 (26 January 2026) and benchmarks published August to September 2025. I have not tested the game myself; every number is attributed to the outlet that measured it, and my own arithmetic is labelled. Values may change if Konami patches the game again.
Quick Start: Seven Changes in Order
- Let the first-launch shader setup finish. It runs for about three minutes and again after a GPU driver change (TechPowerUp). Don’t close it.
- Graphics Quality: High, not Ultra. It is the biggest single lever you have, and Konami’s own tested recommended settings use High.
- Anti-Aliasing Method and Upscaling: DLSS on RTX cards, FSR 3 on others, Quality at 1080p or Balanced at 1440p and 4K. There is no “Off” option for anti-aliasing.
- Global Illumination: High. Medium if you are a few FPS short and accept flatter lighting. Leave Low alone.
- Motion Blur off. Depth of field can be switched off in gameplay, but it stays on in cutscenes.
- Maximum Frame Rate: leave it at 60. The menu only offers 30 or 60.
- Skip the Engine.ini tweaks (hardware Lumen, frame generation) unless you accept that they are unofficial and one of them can crash a cutscene.
What the Settings Menu Has, and the Two Things It Doesn’t
The menu has a short list of graphics options, and neither a Lumen toggle nor frame generation is among them. TechPowerUp’s settings page lists what you can change, and Konami’s tested-settings post names the individual quality rows.
| Setting | Options | What to know |
|---|---|---|
| Graphics Presets | High Quality / Balance / Performance | Switches the upscaling and the quality preset together |
| Graphics Quality | Low / Medium / High / Ultra | The preset that matters most for FPS |
| Anti-Aliasing Method | TSR / DLSS / FSR | No Off option and no XeSS; Intel GPUs can use FSR (TechPowerUp, PCGamingWiki) |
| Upscaling Quality | Native / Quality / Balanced / Performance | See the internal-resolution caveat below |
| Shadows, Textures, Global Illumination, Bloom, Motion Blur | Per-setting quality levels | Named in Konami’s tested settings; DSOGaming also lists Effects |
| Maximum Frame Rate | 30 or 60 | No higher value, even on a 144 Hz monitor |
Two things are missing. First, Lumen: the game uses software Lumen for reflections and global illumination, and TechPowerUp states that hardware Lumen “is not activated in Metal Gear Solid, no matter the GPU.” Second, frame generation: TechPowerUp, DSOGaming and Karan Benchmarks all report that the game does not support it. Both can be forced through a config file, which I cover further down.
One launch-build quirk is worth knowing. PCGamingWiki reports, from a Special K check at 4K output, that DLSS Quality rendered at 2880 × 1620 and Balanced at 2573 × 1448, higher internal resolutions than those modes normally use. That means DLSS Quality costs more than you would expect, and it is one more reason to try Balanced before blaming the preset. The MGSDeltaFix mod has an option to correct it. I could not confirm whether a later patch changed this.
What Each Lever Costs, Measured
Across four outlets, the quality preset and upscaling are the big levers, and single sliders are small. The table collects every measured figure I could find, with the hardware, so you can match it to your own GPU rather than trust a headline number.
| Lever | Measured gain | Test conditions | Source |
|---|---|---|---|
| Ultra → High preset | +14–18% | RTX 5080, native 4K | DSOGaming |
| Ultra → High preset | +18–24% | RTX 4080, native 1440p, three outdoor scenes | TechPowerUp (my arithmetic from its FPS figures) |
| Ultra → High preset | +13% (site states +15%) | RTX 4090, 4K, dense vegetation | PC Optimized Settings (my arithmetic: 46 → 52 FPS) |
| Ultra → Low preset | +52–58%; +55% | RTX 5080 4K; RTX 4090 4K (46 → 71.5 FPS) | DSOGaming; PC Optimized Settings |
| Global Illumination Ultra → Medium / Low | +9% / +15–16% | RTX 4090, 4K, dense vegetation | PC Optimized Settings |
| Shadows Ultra → Medium / Low | +11% / +20% | Same test | PC Optimized Settings |
| DLSS vs native 4K: Quality / Balanced / Performance | +33% / +44% / +72% | RTX 4090, 4K | PC Optimized Settings |
| Hardware Lumen via config | about 5–6 FPS lost | RTX 5080, no baseline given | Wccftech |
The cleanest cross-check is the Ultra-to-Low row: DSOGaming’s 52–58% and my 55% from PC Optimized Settings’ own FPS figures agree on different GPUs. The High row is where the sources spread out, because each tested a different card and scene.
Where the Sources Disagree
They disagree most on how much GPU you need for 1080p Ultra at 60 FPS. TechPowerUp measured that an RTX 4070 Ti, RTX 5070 Ti, RX 7900 XT or RX 9070 is the floor. DSOGaming, testing the first area with Ocelot’s unit, put it at an RX 9070 XT or RTX 5080. GameGPU says an RX 6700 XT or RTX 3060 gives comfortable 60 FPS at 1080p Ultra, without saying which scene it used. Different scenes and methods probably explain most of the gap, though none of the three publishes enough to prove it. I plan from the heavier results, because the jungle and swamp areas are where the lowest frame rates show up, and PC Optimized Settings tested in dense vegetation for exactly that reason.
TechPowerUp also says Ultra, High and Medium “pretty much all look the same” in its comparison screenshots while the frame rate rises significantly. If you take one thing from this guide, it is that you are not giving up visible quality by leaving Ultra.
Global Illumination: Pick High, Use Medium Only If You Must
Global Illumination is the setting closest to Lumen, and it is the one slider worth a deliberate choice. It is the light that bounces off surfaces and fills shadowed areas, and with Lumen it is calculated while you play rather than baked in beforehand, so it costs GPU time on every frame.
PC Optimized Settings measured Medium at 9% faster than Ultra and Low at 15–16% faster, and says Low disables Lumen outright at a drastic cost in fidelity. That is a single-site claim and I could not find a second outlet that isolated the setting, so treat Low as a lead, not a fact. Karan Benchmarks calls Medium a small boost with a major drop in lighting quality, and recommends High. Konami’s own recommended-spec settings use High. My pick follows: High, then Medium if you need the extra 9% and can live with flatter lighting. The gap between High and Ultra for this slider alone is not published anywhere I found.
Shadows cost more than Global Illumination in the same test (Medium +11%, Low +20%, against +9% and +15–16% for GI). I would stop at Medium for both. If you need more FPS after High, DLSS Balanced gave more than any single slider in the table above, and in my judgment it costs less visible quality than dropping lighting or shadows further.
Stutter, Shader Compilation and Patch 1.2.4: What Is Documented
Patch 1.2.4 documents no performance change at all. Konami’s notes list “Minor text fixes” and “Minor bug fixes and adjustments,” and DSOGaming’s write-up says Virtuos made no PC performance improvements and does not expect a performance patch. The only earlier note that touches performance is Patch 1.2.1, which says “Improved overall performance stability.”
| Patch | Date | What Konami’s notes say |
|---|---|---|
| 1.1.3 | 8 Sep 2025 | “Resolved most issues that could cause the game to crash”; performance stability listed as under investigation (notes) |
| 1.2.1 | 30 Oct 2025 | 21:9 support, an in-game system-information viewer, “Improved overall performance stability” (notes) |
| 1.2.2 and 1.2.3 | 13 and 20 Nov 2025 | Mostly Fox Hunt multiplayer changes; “Minor bug fixes and adjustments” for the main game |
| 1.2.4 | 26 Jan 2026 | “Minor text fixes” and “Minor bug fixes and adjustments” (notes) |
What the measurements say about stutter depends on when they were taken. TechPowerUp’s review found that the game compiles shaders for around three minutes on first startup or after a driver change, labelled “setup in progress,” and that once in-game there was no noticeable stutter from shader compilation or other kinds of lag. Digital Foundry’s PC review, as summarised by Multiplayer.it, says the shader precompilation drastically reduces stuttering. The practical rule is to let the setup finish and expect it again after a driver update.
Both reviews tested the launch build, before Patch 1.2.1. So when a guide says Unreal Engine 5 traversal stutter “survived” Patch 1.2.4, nobody I could read has measured it either way. There is also a structural reason to doubt a big traversal problem: TechPowerUp notes the maps are small, with a loading screen every few minutes, and Digital Foundry describes contained areas as in the PS2 original, so the game rarely streams one continuous open world. The same Digital Foundry summary does flag CPU load rising in larger areas and with many active enemies, and says an older Ryzen 5 3600 may struggle.
One contrary source is worth naming. Tier1Settings says shaders keep compiling as you meet new effects for the first hour. It also tells readers to set the frame-rate limit to “Unlimited,” an option TechPowerUp and PCGamingWiki say does not exist, so I weight it low. If you do see hitching, check that the game is on an SSD (Konami’s requirements recommend one), update your driver and then let the shader setup run again, and read our guide to frame pacing stutter before changing graphics settings.
The 60 FPS Cap and Frame Generation: The Rule for Stealth
The rule is simple: get a native 60 FPS first, and treat frame generation as an unofficial extra you probably don’t need. The game’s frame limit is 30 or 60, and TechPowerUp, DSOGaming and PCGamingWiki all say there is no support for higher values in the campaign. Frame generation is not in the menu either, so the only route is a config edit.
That edit is documented by three outlets. The same three lines appear on DSOGaming, Wccftech and PCGamingWiki, added under [SystemSettings] in Engine.ini (in %LOCALAPPDATA%\MGSDelta\Saved\Config\Windows): r.Streamline.DLSSG.Enable=1, t.Streamline.Reflex.Enable=1 and t.Streamline.Reflex.Mode=1. Back up the file first. PCGamingWiki’s longer recipe also has you copy NVIDIA Streamline files for ray reconstruction; none of the three says whether frame generation alone needs them.
The verdicts differ. Wccftech reports about 105 FPS on an RTX 5080 with DLSS Performance plus frame generation and says it more than offsets the hardware Lumen cost. PC Gamer says the jump is “enough of a boost for my tastes.” DSOGaming says it got numerous visual artifacts and advises against using it. PC Optimized Settings claims +60–70% at 4K on RTX 40 and 50 cards.
My rule follows our own frame generation guide: the floor is 60 FPS native, because frame generation does not reduce the input delay of your real frames. In this game the in-game cap is 60, so you can only be above that floor by unlocking the cap with a mod, and the sources split on that too. DSOGaming finished the game unlocked with MGSDeltaFix and saw no side effects. Digital Foundry advises against going past 60 because of bugs, and PCGamingWiki calls the framerate unlock experimental. PC Gamer’s uncap mod “can make the game feel a bit stuttery and induce a spot of tearing.”
So: on a 60 Hz screen, keep the cap and fix your FPS with High and upscaling. On a 120 Hz or faster screen, stay at 60 unless you are willing to try MGSDeltaFix; our best frame cap guide covers picking an external limit if you do. Leave frame generation for last, and only if High plus upscaling already holds 60 native.
Hardware Lumen via Engine.ini: Small Gain, One Known Crash
Hardware Lumen is optional and unofficial, and it is the one tweak with a documented crash. Wccftech measured it at about 5–6 FPS lost on an RTX 5080, and PC Gamer’s Nick Evanson, on an RTX 5090, found “there isn’t a great deal of difference between software and hardware Lumen modes” in the area he checked. The lines are four HardwareRayTracing variables for Lumen (listed on DSOGaming’s page).
The risk is documented twice. PCGamingWiki and DSOGaming both say hardware Lumen can crash the game during the cutscene after the first fight with Volgin, and that removing the lines fixes it. DSOGaming repeated the warning for Patch 1.2.4: there is still no in-game setting for it. That cutscene belongs to the Volgin encounter, one of the five fights our Metal Gear Solid Delta beginner’s guide says stealth cannot finish. For a small visible gain and a crash on one of the game’s best-known scenes, I would leave it off.
Best Settings by GPU
Start from the row that matches your card and adjust one setting at a time. The numbers are what each source reported, not guarantees, and the CPU caveat applies to every row.
| Your GPU | Start here | Evidence |
|---|---|---|
| RTX 2060 Super class (minimum spec) | 1080p, Medium, DLSS Performance, 30 FPS cap | Konami tested this and states it runs at 30 FPS |
| RTX 3060 Ti class | 1080p, High, DLSS Quality, GI High | Karan Benchmarks (i5-13600K): 38 FPS at Ultra with native DLAA, 55 FPS on its reduced “Optimized” settings, 60 FPS with DLSS 4 Quality |
| RTX 3080 to RTX 4070 Ti class | 1440p, High, DLSS Balanced, 60 FPS cap | Konami’s recommended spec, tested at 60 FPS on an RTX 3080 |
| RTX 4080 or faster, 1440p | High, no or light upscaling, 60 cap | RTX 4080 averaged 55–57 FPS at Ultra native and 65–68 at High (TechPowerUp) |
| Any card at native 4K | High plus DLSS Quality or Balanced | No GPU holds 60 FPS at native Ultra 4K (TechPowerUp, DSOGaming); RTX 4090 gets +33% from DLSS Quality (PC Optimized Settings) |
VRAM is rarely the limit: TechPowerUp measured slightly under 10 GB at maximum settings and 4K and around 7 GB at lower resolutions, so 8 GB cards are fine with upscaling and 6 GB cards are tight. If you are weighing other new releases, our settings pieces for 007 First Light and Resident Evil 9 also name the few settings that matter most. For the upscaler choice, see DLSS vs FSR vs XeSS.
Which Setup Fits How You Play
The right changes depend less on your GPU than on your monitor and how much tinkering you want. This table gives different advice per player type, built from the findings above.
| If you are | Do this | Avoid |
|---|---|---|
| A press-play player on a 60 Hz screen | High preset, GI High, DLSS or FSR Quality, cap at 60 | Engine.ini edits and the frame unlock; there is nothing to gain from either |
| A 144 Hz owner who hates the 60 cap | Hit native 60 on High first; try MGSDeltaFix only after backing up your save and files | Frame generation as a fix for a base rate under 60 |
| A tinkerer who wants the best lighting | Hardware Lumen via Engine.ini on a strong GPU, with the lines removed before the Volgin fight | Leaving hardware Lumen on through that cutscene |
| On a 6 to 8 GB card | Keep Textures at High or lower, use upscaling, expect to tune per area | Maximum settings at 4K, which approach 10 GB of VRAM |
FAQ
Does Metal Gear Solid Delta support ray tracing on PC?
Not in the menu. The game uses software Lumen, and hardware Lumen can only be forced through Engine.ini. It costs a little FPS and can crash one cutscene, so most players should skip it.
Is Ultra worth it over High?
No. TechPowerUp says Ultra, High and Medium look nearly the same, while High is 18–24% faster on its RTX 4080 and 14–18% faster on DSOGaming’s RTX 5080. Pay for Ultra only if you already hold 60 FPS with room to spare.
Should I unlock the 60 FPS cap?
Only on a 120 Hz or faster monitor, and only if you accept some risk. DSOGaming finished the game unlocked without problems, but Digital Foundry advises against it and PCGamingWiki calls the unlock experimental. On a 60 Hz screen there is nothing to gain.
Why does the game sit on “setup in progress” for minutes?
It is compiling shaders. TechPowerUp measured about three minutes on first startup and again after a driver change. Waiting is the point: the same review found no noticeable shader stutter in play afterwards.

I've been playing video games for over 20 years, spanning everything from early PC titles to modern open-world games. I started Switchblade Gaming to publish the kind of accurate, well-researched guides I always wanted to find — built on primary sources, tested in-game, and kept up to date after patches. I currently focus on Minecraft and Pokémon GO.
