Lossless Scaling’s LSFG 3 update was announced on January 10, 2025—four days after Nvidia introduced DLSS 4 Multi Frame Generation. It adds a new architecture, claimed image-quality and latency improvements, and an adjustable frame-generation multiplier reaching X20. That sounds like a direct software rival to Nvidia’s feature, but the practical comparison is more nuanced: LSFG 3 is an external, broadly compatible utility, while DLSS Multi Frame Generation is integrated into supported games and requires GeForce RTX 50-series hardware.
What happened: Nvidia announced first, but LSFG was not new to multi-frame generation
Nvidia unveiled DLSS 4 and Multi Frame Generation at CES on January 6, 2025. Nvidia described a system capable of generating up to three additional frames for every traditionally rendered frame on supported GeForce RTX 50-series graphics cards and laptops. Nvidia’s DLSS 4 announcement positioned the feature as part of a deeper game-engine and hardware-integrated pipeline.
Lossless Scaling announced LSFG 3 on January 10, 2025. The timing explains the headlines, but it does not mean LSFG 3 suddenly invented multi-frame generation in response to Nvidia. Earlier Lossless Scaling updates had already introduced higher multipliers: LSFG 2.1 added X3 support in June 2024, and X4 appeared in later LSFG 2.3 development. The earlier Lossless Scaling announcements provide that chronology.
The accurate takeaway is therefore: LSFG 3 expanded an existing external frame-generation system with an unlocked multiplier shortly after Nvidia revealed its own multi-frame technology. It should not be described as an equivalent version of DLSS 4.

What LSFG 3 introduced
According to the developer’s announcement, LSFG 3 brings a new architecture and improvements in four main areas. These figures are developer-reported comparisons, not independent benchmark results.
Claimed image-quality improvements
Lossless Scaling says LSFG 3 reduces flickering and border artifacts while improving motion clarity and overall smoothness. Those changes may make generated output cleaner than earlier LSFG 2 modes, but they do not eliminate the normal weaknesses of external frame generation.
Users can still encounter ghosting around moving objects, distortions in particles and transparencies, flicker on foliage or thin geometry, and incorrect processing of subtitles, HUD elements, overlays, or rapidly scrolling text.
Lower GPU load
The announcement claims approximately 40% lower GPU load in X2 mode than LSFG 2’s non-performance mode, and more than 45% lower GPU load above X2 against that same LSFG 2 baseline. These percentages do not mean LSFG 3 is 40–45% cheaper than DLSS, AMD Fluid Motion Frames, or native rendering. They describe a comparison with an earlier Lossless Scaling mode under the developer’s stated test conditions.

Lossless Scaling reported approximately 24% better end-to-end latency at 40 base FPS in X2 mode, measured with the OSLTT tool against LSFG 2. That is a useful data point, not a universal latency guarantee.
Latency still depends heavily on base FPS, frame pacing, GPU utilization, capture mode, display refresh rate, and frame-limiter behavior. A game producing 40 original frames per second can look smoother after frame generation, but its simulation and input response remain fundamentally tied to that 40-FPS base.
An adjustable multiplier up to X20
LSFG 3 removes the earlier fixed-multiplier ceiling and allows the user to select a multiplier up to X20. In simple terms:
- X2: one generated frame for each original rendered frame.
- X3: two generated frames for each original frame.
- X4: three generated frames for each original frame.
- X20: a highly aggressive output multiplier, not twenty natively rendered game frames.
The distinction between base FPS and displayed FPS matters more than the headline number. For example, 40 base FPS at X3 can produce roughly 120 displayed FPS, but it does not provide the same responsiveness or image quality as a game natively rendering at 120 FPS.
| Base FPS | Multiplier | Approximate displayed FPS | Practical interpretation |
|---|---|---|---|
| 30 | X2 | 60 | A reasonable entry point if frame pacing is stable. |
| 40 | X3 | 120 | Useful for a 120-Hz display, but controls still feel like a 40-FPS game. |
| 48 | X5 | 240 | Mostly relevant to high-refresh-rate displays. |
| 60 | X6 | 360 | Technically possible output target, not native 360-FPS performance. |
| 60 | X8 | 480 | Primarily an experimental or unusually high-refresh configuration. |
These are target calculations from the developer’s guidance, not guaranteed results. The useful range for most players is far below X20.
LSFG 3 versus Nvidia DLSS 4 Multi Frame Generation
Both technologies insert generated frames between traditionally rendered frames to make motion appear smoother. Nvidia’s implementation can generate up to three additional frames per rendered frame, while LSFG 3 exposes a configurable multiplier up to X20.

Calling LSFG 3 “universal” is also too broad. It is broadly compatible because it operates outside a game’s native frame-generation system, not because every game, overlay, anti-cheat system, HDR mode, or fullscreen presentation path works perfectly.
Nvidia’s DLSS 4 system has the advantage of engine-provided motion data and deeper integration. LSFG 3 has the advantage of working with software that lacks native DLSS support. They solve overlapping problems through different paths.
Recommended LSFG 3 settings
Lossless Scaling recommends at least 30 base FPS at 1080p, with 40 FPS or higher preferred and 60 FPS ideal. It disables frame generation when the base rate drops below 10 FPS, but that is an emergency behavior—not a sensible target for playable gaming.
- Start at X2. It is the least aggressive mode and usually the easiest place to evaluate artifacts and pacing.
- Maintain a stable 40–60 base FPS. A stable 40 FPS often produces a better experience than an unstable 70 FPS with frequent drops.
- Cap the game’s frame rate. Leave GPU headroom for capture and frame generation instead of allowing the game to pin the GPU at 100%. Use the game’s limiter where possible, or another limiter if necessary.
- Match the output to the display. For example, 60 FPS on a 120-Hz display is a natural X2 target. X4 is more plausible on a 240-Hz display than X20.
- Reduce the input workload at higher resolutions. The developer suggests roughly 75% Flow/Resolution Scale at 1440p and 50% at 4K when reducing workload is necessary.
- Test difficult scenes. Pan the camera quickly and inspect foliage, particles, thin geometry, subtitles, HUD elements, and fast-moving characters before increasing the multiplier.
Do not run LSFG 3 on top of another frame-generation layer unless you are intentionally experimenting. Combining it with DLSS Frame Generation, AMD Fluid Motion Frames, or another external interpolator can produce pacing, latency, and artifact problems that are difficult to diagnose.
Hardware and compatibility requirements
The current Steam listing specifies Windows 10 version 2004 or newer and DirectX 11. Windowed and borderless fullscreen modes are supported. Exclusive fullscreen may require a second-display output configuration, so borderless mode is the safer starting point.
The listing recommends GeForce RTX 30-series, Radeon RX 6000-series, or Intel Arc graphics, while identifying modern integrated graphics as the minimum class. Actual results depend on available GPU resources, resolution, game presentation method, and frame-generation multiplier.
“Works with most games” should not be read as a guarantee. Capture issues, overlays, HDR, variable-refresh behavior, unusual presentation modes, and anti-cheat systems can all change the outcome. Lossless Scaling’s listing says online-game compatibility with anti-cheat systems is not guaranteed. Check the specific game’s rules before using external capture or frame-generation software.
On Linux, the Steam listing points users toward the community-driven LSFG-VK project. That should be treated as a separate project with its own compatibility and maturity rather than identical support from the Windows application.
Why smoothness is not the same as performance
Frame generation increases the number of images shown by the display. It does not proportionally increase the game’s simulation rate, CPU-side responsiveness, input-sampling frequency, native image detail, or actual rendering work.
Imagine a game rendering at 40 FPS on a 120-Hz monitor. LSFG 3 at X3 can fill more of the display’s refreshes with intermediate frames, making camera movement appear much smoother. However, the game still receives input and advances its simulation around the 40-FPS base rate. The result can look closer to a high-refresh experience while feeling less responsive than native 120-FPS rendering.

This is why 60 FPS × X2 is generally more convincing than 20 FPS × X6. The latter may produce a larger output number, but low base FPS makes latency and interpolation errors more obvious.

It is compelling for
- Owners of older Nvidia, AMD, Intel, or integrated GPUs.
- Players of games without native DLSS, FSR, or frame-generation support.
- Users of emulators, older games, and other applications outside the modern DLSS ecosystem.
- Players with a high-refresh-rate display and a stable 30–60 FPS base rate.
- Anyone seeking smoother output without immediately replacing a graphics card.
It is less compelling for
- Competitive players who prioritize the lowest possible input latency.
- Games whose base FPS regularly falls below 30–40 FPS.
- Systems with no spare GPU resources after native rendering.
- Players already satisfied with a high native frame rate.
- RTX 50-series owners playing games with well-integrated DLSS 4 Multi Frame Generation.
Is the $6.99 utility worth it?
The U.S. Steam listing showed Lossless Scaling at $6.99 when checked; regional pricing and availability can differ. At that price, it is an unusually inexpensive experiment for someone who already has a stable base frame rate, a suitable windowed or borderless game, and a high-refresh monitor.
It is not a substitute for a faster GPU when the game is genuinely struggling at 15–25 FPS. Nor is X20 a reason by itself to buy the application. The value comes from adding a practical X2 or X3 option to games that lack native frame generation—not from turning low-FPS rendering into native high-FPS responsiveness.
Buying an RTX 50-series card solely for Multi Frame Generation is a much larger decision. DLSS 4 is preferable when the user already owns compatible hardware, plays supported games, and values engine integration, motion data, and Nvidia’s broader pacing and Reflex ecosystem. For a handful of older or unsupported games, the low-cost software route is usually the more proportionate choice.

Troubleshooting checklist
- Output looks uneven: lock the game’s base FPS and leave GPU headroom.
- Controls feel delayed: raise base FPS, reduce the multiplier, and avoid treating generated FPS as input responsiveness.
- HUD or subtitles warp: test a different capture mode or disable frame generation for that title if the interface remains distracting.
- Foliage and particles flicker: compare X2 with higher multipliers; aggressive modes expose interpolation errors more readily.
- Capture does not work: switch from exclusive fullscreen to windowed or borderless fullscreen.
- VRR behaves poorly: test with and without VRR and adjust the frame cap below the monitor’s maximum refresh rate.
- Online play is a concern: check the game and anti-cheat provider’s rules; no universal safety guarantee applies.
- Another frame-generation system is active: disable one layer before diagnosing performance or image quality.
Frequently Asked Questions
Does LSFG 3 provide the same technology as DLSS 4 Multi Frame Generation?
No. Both generate intermediate frames, but LSFG 3 is an external capture-based utility with broad software compatibility, while DLSS Multi Frame Generation is integrated into supported games and relies on RTX 50-series hardware and Nvidia’s DLSS pipeline.
What does LSFG 3 X20 mean?
X20 is an output multiplier. It can display many generated frames between traditionally rendered frames, but it does not create twenty native game frames and does not provide native 20-times responsiveness.
What base FPS should I target?
Lossless Scaling recommends at least 30 FPS at 1080p, prefers 40 FPS or higher, and identifies 60 FPS as ideal. Stable base frame rate and pacing matter more than maximizing the multiplier.
Can Lossless Scaling be used safely with every online game?
No guarantee applies. The Steam listing says anti-cheat compatibility is not guaranteed, so check the rules for the specific game before using it.

The Bottom Line
Bottom line: LSFG 3 is a flexible, low-cost way to make compatible games look smoother, especially when native frame generation is unavailable. Its X20 ceiling is attention-grabbing but rarely the important part. Start with a stable 40–60 FPS base, use X2 or X3, preserve GPU headroom, and remember that displayed FPS is not the same as native performance or input responsiveness. DLSS 4 remains the more deeply integrated solution for supported games on RTX 50-series hardware.
