The GTX 1660 Super launched in 2019 as NVIDIA’s budget 1080p champion, and it holds that position in 2026 — if you know which settings to touch. The problem most guides skip is the 6 GB VRAM ceiling: push textures too hard and you’re not losing frames gradually, you’re triggering texture-streaming stutter that no slider can fix.
This guide gives you the complete settings stack: NVIDIA Control Panel globals, a VRAM budget breakdown, per-game recommendations for eight popular titles, and the FSR strategy that replaces DLSS on this card.
GTX 1660 Super in 2026: Specs and What to Expect
The 1660 Super runs NVIDIA’s Turing architecture with 1,408 CUDA cores, a 1,815 MHz boost clock, and 6 GB GDDR6 over a 192-bit bus. That GDDR6 memory runs at 14 Gbps — delivering 336 GB/s of bandwidth — notably faster than the standard 1660’s GDDR5. The bandwidth advantage means the card feeds its shaders efficiently at 1080p; the 6 GB capacity, not bandwidth, is where things get tight.
| Spec | GTX 1660 Super |
|---|---|
| Architecture | Turing (TU116) |
| CUDA Cores | 1,408 |
| Boost Clock | 1,815 MHz |
| VRAM | 6 GB GDDR6 |
| Memory Bandwidth | 336 GB/s |
| TDP | 125W |
| DLSS | No |
| Hardware Ray Tracing | No |
Two things missing from this card matter directly for 2026 optimization: hardware RT cores and DLSS Tensor cores. Skip ray tracing entirely; use FSR instead of DLSS. For 1080p gaming, the 1660 Super delivers 60+ FPS at High settings in most titles and 100+ FPS in esports games — benchmarks show Fortnite averaging 112 FPS at High, CS:GO at 298 FPS at maximum settings, and GTA V at 88 FPS at Very High.
NVIDIA Control Panel: Global Settings for GTX 1660 Super
These driver-level settings apply across every game and stack with your in-game adjustments. Set them once.
| Setting | Value | Why |
|---|---|---|
| Power Management Mode | Prefer Maximum Performance | Stops GPU clock throttling mid-game |
| Low Latency Mode | On | Reduces input lag at no quality cost |
| Texture Filtering — Quality | High Performance | Frees shader time for geometry work |
| Anisotropic Filtering | 16x | Near-zero FPS cost; large sharpness gain |
| Vertical Sync | Off | Let the game control V-Sync |
| Shader Cache Size | Unlimited | Prevents Unreal Engine stutter on first loads |
Keep Antialiasing — FXAA set to Off. Modern games use TAA internally, and FXAA applied on top blurs the image with no FPS gain. For a full walkthrough of every Control Panel option, see the NVIDIA Control Panel Best Settings for Gaming 2026 guide.
The 6 GB VRAM Budget — Which Settings Eat It First
The 1660 Super’s 6 GB VRAM is almost never the bottleneck in esports titles — the shaders run out of work before VRAM fills up. In modern AAA games, the story flips: Ultra texture packs alone can consume 5–7 GB, pushing the card over its ceiling.
When VRAM fills up, the driver streams textures from system RAM. That shows up as hitches every time a new area loads — frame-time spikes that average FPS numbers hide completely. A card averaging 60 FPS with 200 ms spikes every 10 seconds feels broken; a card at 55 FPS with consistent frame pacing feels smooth. The 1660 Super’s VRAM constraint is a stutter trigger, not a frame rate cap.
| Setting | VRAM Impact | Recommendation |
|---|---|---|
| Texture Quality (Ultra to High) | High — saves 500–800 MB | Set to High, not Ultra |
| Shadow Map Resolution | Medium | High or Medium |
| Ambient Occlusion (HBAO+ to SSAO) | Low–medium | Use SSAO, not HBAO+ |
| Screen Space Reflections | Medium | Medium or Off |
| Anti-Aliasing (MSAA to TAA) | Medium — MSAA multiplies VRAM use | Use TAA, not MSAA |
The rule: drop textures from Ultra to High before touching anything else. That single change typically frees 500–800 MB — often the margin between smooth gameplay and streaming hitches. For a full explanation of what these settings actually do under the hood, the PC Game Settings Explained guide breaks down each option in plain terms.
Per-Game GTX 1660 Super Settings at 1080p
These targets are based on tested FPS data at 1080p. The Key Adjustments column lists the changes from the named preset that make the biggest difference on this card.
| Game | Preset | Key Adjustments | Target FPS |
|---|---|---|---|
| Fortnite | High | Shadows: Off, Post Processing: Low | 120–150 |
| CS2 | High | Motion Blur: Off | 150–200+ |
| GTA V | Very High | MSAA: Off (use FXAA); Grass: High | 85–100 |
| Cyberpunk 2077 | Medium | FSR Quality mode; RT: Off | 55–65 |
| Elden Ring | High | Motion Blur: Off | 60 stable |
| Red Dead Redemption 2 | Medium | Shadows: Medium; Reflections: Off | 55–65 |
| Assassin’s Creed Mirage | Medium | Environment Quality: Medium | 60–70 |
| Valorant | High | Anti-Aliasing: MSAA 2x; Shadows: Off | 200+ |
Fortnite note: disabling shadows is the single highest-value change on this card for competitive play — it trades nothing visually in a match and unlocks 20–30 FPS. Cyberpunk note: without FSR, the card hits its VRAM ceiling at Medium textures causing periodic stutter; FSR Quality mode renders at 77% resolution before upscaling to 1080p, eliminating that constraint while adding FPS headroom.
No DLSS? Use FSR Instead
DLSS requires Tensor cores. The GTX 1660 Super doesn’t have them. AMD’s FidelityFX Super Resolution (FSR) is the answer — it’s open-source, vendor-agnostic, and runs on any GPU including this one.
FSR 2 and FSR 3 are now supported in over 300 games. At FSR Quality mode, the game renders at 77% of your target resolution and upscales to 1080p. The image is near-indistinguishable from native while delivering 20–35% more FPS — the difference between Cyberpunk 2077 at 45 FPS and 60+ FPS on this card.
Use FSR Quality or Balanced only. FSR Performance mode renders at 50% resolution, which at 1080p is too soft to be worth the trade. If a game supports FSR 2 or FSR 3, the temporal component handles motion artifacts far better than FSR 1 — always prefer the newer version when available.
Esports vs. AAA — Two Different Optimization Targets
The GTX 1660 Super needs two distinct strategies depending on what you’re playing. Mixing them is the most common mistake.
Esports (Fortnite, CS2, Valorant, Apex Legends): Target 120–160+ FPS. Raw frame rate beats visual quality every time. Disable shadows entirely, set post-processing to Low or Off, keep textures at High. The card has surplus compute for competitive esports at 1080p — the settings work is about removing overhead, not compensating for hardware limits.
AAA single-player (Cyberpunk 2077, RDR2, Elden Ring): Target 60 FPS locked. Enable FSR Quality if supported. Keep textures at High — not Ultra — drop shadows to Medium, and disable motion blur and depth of field. Both are cosmetic effects with zero gameplay function that consume VRAM and shader time the card can’t spare at AAA settings.
The trap to avoid: applying AAA-style conservative settings to esports games. Fortnite and CS2 are engineered to scale to high frame rates, and the 1660 Super can deliver 120+ FPS in both. Don’t cap it at 60 where it doesn’t need to be.

FAQ
Can the GTX 1660 Super still play games in 2026?
Yes, at 1080p. Esports titles run at 120–200+ FPS, and AAA games at Medium/High settings hit 55–65 FPS. The 6 GB VRAM starts to bind in the most texture-heavy AAA titles at Ultra settings, but at High settings the card is still capable for 1080p gaming.
Is 6 GB VRAM enough in 2026?
For 1080p at Medium–High settings, yes. For Ultra textures in modern AAA games, no — you’ll see texture-streaming hitches rather than a hard FPS cap. Keep textures at High across the board and you stay within budget. At 1440p, VRAM becomes genuinely constrained even at Medium settings.
Should I overclock my GTX 1660 Super?
A modest +100–150 MHz core overclock is generally stable and yields 5–8% more performance. Use MSI Afterburner, run a benchmark loop to verify stability, and raise the power limit before touching voltage. Clean your GPU fans first — a 1660 Super throttling from dust buildup is frequently mistaken for needing an overclock.
When should I upgrade from a GTX 1660 Super?
If 60 FPS at 1080p is acceptable and esports is your primary game type, there’s no urgency. If you’re hitting VRAM limits in AAA games regularly or want 1440p at playable frame rates, it’s time to move on. The Best Mid-Range GPUs 2026 guide covers current upgrade options at different price points.
