Lossless Scaling’s LSFG 3 was a substantial frame-generation update, but “24% lower latency” needs careful context. Released on January 10, 2025 as part of Lossless Scaling 2.13, LSFG 3 reportedly reduced end-to-end latency by approximately 24% versus LSFG 2 in a developer-run OSLTT test at 40 FPS with X2 generation. The same announcement claimed about 40% lower GPU load in X2 mode and more than 45% lower load above X2.
Those are meaningful improvements to an external frame-generation tool—not proof that generated 80 FPS responds like native 80 FPS. The game still simulates and samples input at its base rate. Later 2025 updates, including Adaptive Frame Generation and LSFG 3.1, made the utility more flexible and improved image quality.
The short version
Lossless Scaling is worth considering when a game lacks built-in DLSS, FSR, XeSS, or another frame-generation option, provided the game can maintain a reasonably stable base frame rate. Start with X2, cap the game’s real frame rate, and leave GPU headroom for the generation pass.
It is usually not the first choice when a game already offers well-integrated native frame generation, especially for competitive games. Native solutions can access engine motion data and timing that an external capture utility generally cannot.

What LSFG 3 actually changed
The terminology matters. LSFG 3 is the frame-generation technology; it was not the same thing as a full “Lossless Scaling 3” application release. The January 2025 announcement delivered Lossless Scaling 2.13 with LSFG 3, while a separate Lossless Scaling 3.0 UI beta was available through Steam’s Betas menu. The developer’s release announcement is recorded on Steam Community.
LSFG 3’s reported improvements included:
- Lower latency: approximately 24% better end-to-end latency than LSFG 2 in the developer’s stated test.
- Lower GPU overhead: approximately 40% lower GPU load in X2 mode, and more than 45% lower above X2, compared with LSFG 2 outside Performance mode.
- Improved presentation: reduced flickering and border artifacts, plus better motion clarity and smoothness.
- Unlocked multipliers: frame-generation multipliers up to X20 became available, although that ceiling is a capability rather than a sensible everyday setting.
A lower generation-pass workload can create more GPU headroom, but it does not automatically produce a proportional increase in the game’s native FPS. A title may still be CPU-limited, limited by its renderer, constrained by capture overhead, or unable to use the extra frames because of the monitor’s refresh rate.
How meaningful is the 24% latency claim?
The number is best understood as an internal LSFG improvement under defined conditions, not a universal reduction in every part of input delay. The developer compared LSFG 3 with LSFG 2 using the OSLTT latency-testing tool, a 40-FPS base rate, and X2 frame generation.
Tom’s Hardware reported the illustrative measurements as follows:
| Scenario | Reported latency | Displayed output |
|---|---|---|
| Native 40 FPS | 28.47 ms | 40 FPS |
| LSFG 2 at X2 | 54.31 ms | 80 FPS |
| LSFG 3 at X2 | 41.70 ms | 80 FPS |
These are reported measurements, not independent reproductions. They show why the claim is still useful: LSFG 3 was substantially better than LSFG 2 in that test. They also show why generated FPS should not be confused with native responsiveness. The game remains a 40-FPS game from the perspective of simulation and input sampling, even though LSFG displays 80 frames per second.
Frame generation inserts images between rendered frames. It can make camera movement and animation appear smoother, but it cannot make the underlying game logic run twice as often. If the base frame rate is unstable, the generated output may also feel uneven or reveal interpolation errors.
What “Universal Frame Generation” means
Lossless Scaling works as an external Windows utility rather than requiring each game to integrate a vendor-specific SDK. That makes it useful for older games, emulators, indie titles, applications, and games whose developers never added modern frame generation.

“Universal” does not mean flawless or compatible with every presentation path. Ordinary use generally requires the game to run in windowed or borderless fullscreen mode. The Steam listing notes that exclusive fullscreen may require output to a second display. See the Steam product page for the listed compatibility details.

- A capture method compatible with the Windows version and application.
- Lossless Scaling capturing the correct game window.
- A stable base frame rate and consistent frame pacing.
- Enough GPU capacity for both the game and generation process.
- Scenes whose motion can be inferred cleanly from successive frames.
External capture also means the utility has less information than a native implementation. DLSS, FSR, and similar engine-integrated technologies can use motion vectors, depth information, renderer timing, and game-specific UI handling. LSFG must infer motion from the captured output, so thin geometry, particles, reflections, foliage, scrolling text, HUD elements, and rapid camera movement can expose artifacts.
Recommended settings for LSFG 3
Start with X2
X2 is the sensible default for most users. It gives the algorithm one generated frame between each rendered frame and is generally less demanding and less artifact-prone than higher multipliers.
The developer’s starting guidance was:
- 30 FPS: a practical minimum at 1080p.
- 40 FPS: preferred for a good X2 baseline.
- 60 FPS: ideal at 1080p when the hardware can sustain it.
These figures are starting points, not guarantees. A perfectly paced 30 FPS experience may be preferable to an unstable 45 FPS one, but frame generation cannot fully repair sluggish input or severe stutter.
Cap the real game frame rate
Lock the game to the intended base rate where possible. Uncapped rendering can allow the game to consume all available GPU capacity, leaving insufficient room for LSFG and increasing latency or producing inconsistent pacing.
For minimum latency, avoid GPU utilization sitting continuously at 100%. Increase the base frame rate when possible rather than compensating for a weak base rate with a larger multiplier.
Use higher multipliers selectively
X3 and above can be appropriate when the base frame rate is stable and the display refresh rate justifies it. Examples from the developer’s guidance include 48 FPS ×5 for a 240 Hz display, 60 FPS ×6 for 360 Hz, and 60 FPS ×8 for 480 Hz.

Those examples do not make X5 or X8 universally advisable. High multipliers are better suited to single-player games, slower-paced titles, older games, or situations where visual smoothness matters more than competitive latency. They can magnify ghosting, UI errors, and motion-estimation failures.
Adjust resolution and Flow Scale when necessary
The original guidance suggested using a 75% Resolution/Flow Scale at 1440p and 50% at 4K when needed. Treat these as performance-oriented starting points. Lowering the scale can reduce GPU demand, but it may also reduce image quality and make artifacts more visible in fine details.
Fixed versus Adaptive mode
Fixed multipliers are predictable: X2 turns a stable 40 FPS base into an approximately 80-FPS output. Adaptive Frame Generation is more useful when the target refresh rate does not map neatly to an integer multiplier, such as targeting 144 Hz or 165 Hz from a 60-FPS base.
What later updates added
An article about the January 2025 LSFG 3 release is incomplete without the subsequent updates.
Adaptive Frame Generation — March 8, 2025
Adaptive Frame Generation dynamically adjusts fractional multipliers to pursue a target frame rate. That can help match displays such as 144 Hz and 165 Hz more closely than fixed integer multipliers.
The trade-off is that Adaptive mode can increase GPU load and may slightly reduce image quality compared with fixed-multiplier mode. It also added Queue Target options from 0 to 2. Lower buffering generally favors latency, while additional queueing can improve stability when the GPU is heavily loaded.

The update also clarified capture behavior on Windows: WGC capture was unavailable before Windows 11 24H2, so DXGI becomes the fallback on earlier Windows versions when WGC is selected.
LSFG 3.1 — June 11, 2025
LSFG 3.1 focused on image quality, with improvements to ghosting, object flicker, border handling, and UI detection. It also introduced Performance mode. The developer said Performance mode could provide up to twice the GPU-load reduction depending on hardware and settings, at the cost of a modest image-quality trade-off.
July 14, 2025 Performance-mode hotfix
A July 2025 hotfix fixed a critical quality bug affecting LSFG 3.1 Performance mode. Anyone evaluating the feature should use an updated build rather than judging Performance mode from an early 3.1 installation.
Lossless Scaling versus native frame generation
| Consideration | Lossless Scaling / LSFG | Native DLSS, FSR, or similar |
|---|---|---|
| Game support | Broad external applicability, including many older or unsupported games. | Only games that implement the relevant technology. |
| Hardware restrictions | Useful across a wider range of Windows gaming hardware, subject to capture and performance limits. | Depends on the game, vendor, GPU generation, and feature support. |
| Renderer information | Works from captured frames and therefore has less engine context. | Can use engine motion data, depth, timing, and integrated UI handling. |
| Latency control | Depends heavily on base FPS, GPU headroom, capture path, and queue settings. | May include engine- or vendor-integrated latency features. |
| Artifacts | Content-dependent; HUDs, thin objects, particles, and fast motion can be difficult. | Often more predictable when well implemented, though no method is artifact-free. |
| Cost | Paid Steam utility; the listing showed $6.99 during the research pass. | Usually included with the game or driver feature, with hardware compatibility as the main cost. |
| Best use | Unsupported games, emulators, handheld PCs, older GPUs, and high-refresh displays. | Supported modern games where image quality and latency are priorities. |
NVIDIA’s DLSS information, AMD’s FidelityFX Super Resolution documentation, and AMD’s Adrenalin software information describe their respective native or driver-level approaches.
Native frame generation is usually preferable when a game supports it well. Lossless Scaling’s advantage is breadth: it can add a frame-generation option where no integrated solution exists. It should not be presented as automatically superior to DLSS, FSR, XeSS, or AMD Fluid Motion Frames.
Who should buy Lossless Scaling?
Strong fit
- You play games with no native frame generation.
- You use older games, emulators, indie games, or applications outside modern engine pipelines.
- Your base frame rate is stable, ideally 40 FPS or higher.
- You own a high-refresh-rate monitor and value smoother motion.
- Your GPU lacks a vendor-specific frame-generation feature.
- You also want scaling tools such as LS1, FSR, NIS, integer scaling, XBR, or Anime4K, which are listed on the Steam store page.
Conditional fit
- Your game can hold only around 30 FPS but has consistent frame pacing.
- You are willing to tune caps, capture modes, Flow Scale, and multipliers per game.
- You primarily play single-player games where a small latency increase is acceptable.
- Your display is fast enough to benefit from the generated output.
Poor fit
- Your game already has excellent native DLSS, FSR, or XeSS frame generation.
- You play competitive games where minimum latency and artifact-free HUDs matter more than smoothness.
- Your base FPS regularly falls below approximately 30 FPS.
- Your GPU is already saturated by the game.
- Your monitor’s refresh rate is too low to benefit from the output.
The Steam listing says community experience has found Lossless Scaling safe with some online games, but it does not guarantee anti-cheat compatibility. Use discretion, particularly with protected competitive titles, and check the game’s rules before enabling external tools.

Frame generation does not activate
- Set the game to supported windowed or borderless fullscreen mode.
- Confirm that Lossless Scaling is capturing the correct application.
- Disable scaling if you want only frame generation.
- Try the capture method supported by your Windows version. On older Windows builds, DXGI may be the fallback when WGC is selected.
- Check whether the game uses a protected or unusual presentation mode.
- Temporarily disable overlays if capture is unstable.
Stutter or uneven frame pacing
- Lock the game’s base FPS.
- Reduce the multiplier, usually returning to X2.
- Leave additional GPU headroom.
- Try a different Queue Target in Adaptive mode.
- Use Fixed mode when predictable integer scaling is more important than matching an awkward refresh-rate target.
- Use Adaptive mode when the display target does not align with an integer multiplier.
Ghosting, flicker, or HUD artifacts
- Lower the multiplier.
- Raise the base frame rate if possible.
- Test a different Flow Scale.
- Compare LSFG 3.1 Performance mode with normal mode; Performance mode trades some image quality for lower GPU load.
- Compare against native frame generation if the game provides it.
- Treat persistent crosshair or text errors as a limitation of the external method, not necessarily a setting you can eliminate.
Latency becomes worse
- Reduce the multiplier.
- Cap the game before GPU utilization reaches 100%.
- Increase the native base frame rate instead of adding more generated frames.
- Avoid buffering settings intended for unstable or heavily loaded systems when minimum latency is the priority.
- Use the game’s native frame-generation implementation when it offers better integrated latency controls.
Bottom line
LSFG 3 made Lossless Scaling a more convincing universal fallback. The developer’s approximately 24% latency improvement over LSFG 2, combined with claimed GPU-load reductions of about 40% in X2 and more than 45% above X2, addressed two of the tool’s biggest weaknesses.

But the correct buying argument is not “generated FPS equals native FPS.” It is that LSFG can make unsupported games look smoother when the base frame rate is already stable and the hardware has room for the extra processing. Buy it for breadth, older games, emulators, handheld PCs, and high-refresh displays—not as an automatic replacement for a good native implementation.

Frequently Asked Questions
Is LSFG 3 the same as Lossless Scaling 3?
No. LSFG 3 is the frame-generation update initially delivered with Lossless Scaling 2.13. A separate Lossless Scaling 3.0 UI beta was available through Steam’s Betas menu.
Does LSFG 3 make 40 FPS feel like native 80 FPS?
No. It can make motion appear smoother at an 80-FPS display output, but the game still simulates and samples input at 40 FPS, so responsiveness is not equivalent to native 80 FPS.
Crashes, No Sound, or Screen Glitches?
Random freezes, missing sound and display glitches usually trace back to one bad driver. Find and replace yours safely.Free scan · under a minuteWindows Errors? Fix Them Before They Spread

Use higher multipliers only with a stable base frame rate, enough GPU headroom, and a display refresh rate that benefits from them. X2 is the safer starting point, especially for fast or competitive games.
Is Lossless Scaling safe with anti-cheat?
Compatibility is not guaranteed. The Steam listing notes community reports of safe use with some online games, but players should check each game’s rules and use caution.
The Bottom Line
Verdict: LSFG 3 was a real improvement to external frame generation, and later LSFG 3.1 updates strengthened the package. It is most compelling when native frame generation is unavailable. When DLSS, FSR, or another integrated option works well, use the native implementation first.
