An XDA writeup this week landed on a familiar conclusion: Nvidia Smooth Motion is nice when you don’t need it, awkward when you do. That summary applies to almost every driver-level frame-generation trick shipped so far, and it points at a wider question, which frame gen tools actually pull their weight on a mid-range PC? Below are seven we have kept installed after the initial curiosity wore off, spanning first-party driver features, paid utilities, and open-source alternatives.
What to look for in a frame generation tool
Frame generation is not FPS. It is interpolation. What matters:
- Latency added per generated frame (Reflex or Anti-Lag helps)
- Whether it needs game integration or just a window
- GPU compatibility (RTX 40/50, RDNA 3/4, Arc, or any card)
- Scaling behaviour on borderless windowed vs. fullscreen
- Whether it plays nicely with your capture app and HDR
If a tool adds so much latency that a Reflex-off comparison feels sharper, it has failed the smell test regardless of the frametime graph.
Quick comparison
| Tool | Best for | GPU support | Price | Standout feature |
|---|---|---|---|---|
| Lossless Scaling | Any game, any GPU | Any | Paid, one-time on Steam | LSFG works in any window |
| Nvidia App | RTX GPU owners | RTX 20+ | Free | Smooth Motion at driver level |
| AMD Software Adrenalin | Radeon owners | RDNA 3+ | Free | AFMF 2 driver-level FG |
| Intel Graphics Software | Arc GPU owners | Arc / Core Ultra | Free | XeSS FG in supported titles |
| Magpie | Windowed games | Any | Free, open source | FSR, NIS, Anime4K scaling |
| SpecialK | Fine-grained control | Any | Free, open source | Frametime pacing beyond FG |
| ReShade | Injecting DLSS/FSR | Any | Free, open source | DLSS/FSR mods via wrappers |
The tools
1. Lossless Scaling, best for any game, any GPU
Lossless Scaling is the utility that put third-party frame generation on the map. Its LSFG algorithm generates in-between frames from any windowed game, and later versions added 3x and 4x multiplication for people running high-refresh screens on a 40-fps base. Runs on Nvidia, AMD, Intel, and integrated GPUs.
Where it falls short: Latency climbs noticeably at 3x and 4x settings, especially under 40 fps input. Text and UI can ghost during fast camera movement.
Pricing:
- Free: no
- Paid: one-time purchase on Steam, priced like a coffee
Platforms: Windows
Download: Steam
Bottom line: Buy it if you own an older GPU and want frame gen in games that don’t ship with it.
2. Nvidia App, best for RTX GPU owners
Nvidia App consolidates GeForce Experience and the old Control Panel into one tool, and in current drivers it ships Smooth Motion, a driver-level frame generation feature that works in DirectX 11 and DirectX 12 titles without game support. RTX 20-series and newer cards are covered. Overlay recording (ShadowPlay) sits in the same app.
Where it falls short: Smooth Motion needs a fullscreen or exclusive fullscreen game, and the toggle is per-game rather than global. HDR handling still has rough edges in some titles.
Pricing:
- Free: yes
Platforms: Windows
Download: nvidia.com/software/nvidia-app
Bottom line: If the game supports DLSS you probably want DLSS FG first. Smooth Motion covers everything else.
3. AMD Software Adrenalin, best for Radeon owners
AMD Software Adrenalin ships AFMF 2 (AMD Fluid Motion Frames), the Radeon answer to Smooth Motion. It works at the driver level on RX 6000 and newer, and the second-generation implementation added support for windowed mode plus better handling of low base framerates. Anti-Lag 2 in the same suite offsets some of the added latency.
Where it falls short: Motion clarity dips when the base framerate is below 55 fps. AFMF pauses when the camera moves fast, which is a workaround for ghosting but jarring the first time you notice it.
Pricing:
- Free: yes
Platforms: Windows
Download: amd.com/adrenalin
Bottom line: If you already run a Radeon, this is the frame-gen tool you should try before spending money on anything else.
4. Intel Graphics Software, best for Arc GPU owners
Intel Graphics Software exposes XeSS Frame Generation for games with in-engine support and enables Xe-driver features for Battlemage and later cards. Coverage is smaller than Nvidia or AMD, but the game list keeps growing.
Where it falls short: Games without engine integration get no XeSS FG. Driver overhead in some older DirectX 11 titles is still uneven.
Pricing:
- Free: yes
Platforms: Windows
Download: intel.com/graphics-software
Bottom line: Worth installing on any Arc build to keep XeSS support current.
5. Magpie, best for windowed games
Magpie is an open-source scaler that windows-and-upscales any game, and recent builds added a frame generation mode built on top of a similar interpolation approach to Lossless Scaling. FSR, NIS, and Anime4K scaling shaders ship in the box.
Where it falls short: No official installer, comes as a zip. Some anti-cheat middleware treats the injection as suspicious.
Pricing:
- Free: yes, open source
Platforms: Windows
Download: github.com/Blinue/Magpie
Bottom line: The right pick if you want a Lossless Scaling-style tool without paying and don’t mind occasional rough edges.
6. SpecialK, best for fine-grained control
SpecialK is a tuning framework more than a frame gen app on its own. Its real strength is frametime pacing, DLSS/FSR/XeSS injection into games that don’t officially ship them, and per-game HDR fixes. Paired with a game that supports DLSS FG or FSR FG, it lets you tune the last mile the driver won’t.
Where it falls short: The UI is notoriously dense and unforgiving. Some anti-cheat systems will not let SpecialK inject.
Pricing:
- Free: yes, open source
Platforms: Windows
Download: special-k.info
Bottom line: For the enthusiast who wants to fix the exact stutter their monitor is showing.
7. ReShade, best for injecting FG mods
ReShade on its own doesn’t generate frames, but the community shader ecosystem includes DLSS FG and FSR FG wrappers that plug into games without native support. The DLSS Enabler mod, for instance, brings frame gen into titles that shipped with DLSS 2 only. Setup means editing INI files, not much else.
Where it falls short: Community mods are the point, and they are unofficial by definition, expect to reinstall after every game patch. Anti-cheat games are off limits.
Pricing:
- Free: yes, open source
Platforms: Windows
Download: reshade.me
Bottom line: Reach for it when a game shipped with an older upscaler and you want to swap in a newer one.
How to pick the right one
- If you own an RTX card: Nvidia App and Smooth Motion first.
- If you own a Radeon RX 6000 or later: AMD Software Adrenalin and AFMF 2.
- If you own an Arc GPU: Intel Graphics Software.
- If you own an older card or an integrated GPU: Lossless Scaling.
- If you don’t want to pay and don’t mind fiddling: Magpie.
- If your problem is stutter, not raw framerate: SpecialK.
- If you want DLSS FG in a game that shipped without it: ReShade plus DLSS Enabler.
Skip frame gen entirely if your base framerate is under 40 fps in the game you care about, no tool on this list produces a good result at those input rates.
FAQ
Does frame generation add input lag?
Yes, always. Modern tools ship latency-reduction pairings (Reflex, Anti-Lag) to offset it, but the tradeoff never goes to zero. Whether it feels bad depends on the base framerate and how twitchy the game is.
Can Lossless Scaling replace DLSS Frame Generation?
For general use, yes. In games with native DLSS FG on a Nvidia RTX 40 or 50 card, native is usually smoother and lower-latency. Lossless Scaling shines in games without any built-in FG.
Will frame generation work on a laptop GPU?
Lossless Scaling and Magpie work on any Windows GPU, laptop or desktop. Vendor-level FG (Smooth Motion, AFMF, XeSS) depends on your laptop’s exact GPU generation.
Do these tools work with HDR?
Nvidia App and AMD Adrenalin handle HDR cleanly in most cases. Lossless Scaling supports HDR on recent versions, but check the release notes if you’re using a 3x or 4x multiplier.
Is frame gen worth using with a VRR monitor?
Yes. VRR eliminates the frame-pacing quirks that frame gen can otherwise introduce. Cap the generated framerate a few fps below your monitor’s max refresh to stay in the VRR window.
