If you've been using lossless scaling just to upscale games, you're barely scratching the surface of what it can actually do. The latest version has turned it into one of the most powerful performance tools available.
Optimize lossless scaling settings for max FPS and low latency using frame generation, upscaling, and smart pacing on desktops and laptops.
Key Takeaways
- Lossless scaling frame generation significantly boosts FPS without increasing GPU rendering load.
- Advanced configuration beyond enabling frame generation is crucial for optimal smoothness and latency.
- Laptop internal displays uniquely benefit from workload sharing between integrated and dedicated GPUs.
- Combining resolution downscaling with frame generation yields the best balance of performance and image quality.
- Using the latest LS FG version and proper capture API settings reduces input latency and visual artifacts.
What the video covers
- Lossless scaling now offers advanced frame generation (LS FG) to increase output FPS without rendering every frame.
- Use LS FG version 3.1 for cleaner images, fewer artifacts, and lower input latency.
- Choose between fixed mode (simple FPS multiplier) and adaptive mode (dynamic FPS target) for frame generation.
- Avoid fractional multipliers like 1.5x; prefer clean multipliers such as 2x for smoother motion and less GPU stress.
- Adjust advanced settings like flow scale, capture API, and Q target to balance smoothness, latency, and GPU load.
- Windows 11 24H2+ users should select Windows graphics capture for better performance; others should use DXGI.
- Q target settings balance responsiveness and stability, with Q target 0 for lowest latency and Q target 2 for stability under load.
- Gaming laptops benefit uniquely by offloading frame generation to the integrated GPU while the dedicated GPU renders real frames.
- Combining upscaling with frame generation by lowering internal resolution and scaling back up maximizes FPS and image quality.
- Locking base game FPS with RTSS before enabling frame generation helps maintain excellent frame pacing.

Frame generation has improved dramatically. Adaptive modes are smarter than ever, and there are hidden options that can completely change how smooth your games feel. Whether you're gaming on a desktop or trying to squeeze every last frame out of a budget
Speaker A
laptop, this guide will show you how to build the best possible lossless scaling setup from the ground up. By the end, we'll combine frame generation, upscaling, smart frame pacing, and even a little-known laptop trick to get the
Speaker A
most out of your hardware. Let's start with a feature that changes everything. Build your frame generation foundation.
Speaker A
Modern versions of lossless scaling aren't just about increasing resolution anymore. The real game-changer is LS FG, or lossless scaling frame generation. Instead of asking your GPU to render every frame itself, LS FG creates additional frames between
Speaker A
the ones your graphics card actually renders. Your GPU handles the real frames. Lossless scaling fills in the gaps. The result is dramatically higher output frame rates without requiring your GPU to render every single frame. Before changing anything
Speaker A
else, make sure you're using LS FG 3.1. Compared to earlier versions, it offers cleaner image reconstruction, fewer visual artifacts, and noticeably lower input latency.
Speaker A
Once that's done, you'll need to choose how frame generation behaves. You have two options. Fixed mode simply multiplies your current frame rate. A 30 FPS game becomes roughly 60 FPS using 2x, or even higher with larger
Speaker A
multipliers. It's simple and predictable. The second option is adaptive mode. Instead of sticking to one multiplier, you choose a target frame rate, and lossless scaling automatically adjusts frame generation to keep you as close as possible.
Speaker A
For games where performance constantly changes, adaptive mode usually delivers a smoother overall experience. One recommendation here is to avoid fractional multipliers whenever possible. While values like 1.5x may sound appealing, clean multipliers such as 2x generally provide smoother motion
Speaker A
while placing less unnecessary stress on your GPU. Now that frame generation is working properly, let's refine how it behaves.
Speaker A
Fine-tune the engine behind the scenes. Most people stop after enabling frame generation. That's where they leave a surprising amount of performance behind.
Speaker A
Open the advanced settings. The first option worth adjusting is flow scale. This controls how aggressively generated frames blend together. Increasing it can make motion appear smoother, but it also increases GPU workload.
Speaker A
If your graphics card already runs near full utilization, pushing this too high can actually introduce stuttering instead of eliminating it. For most systems, staying close to the default value provides the best balance. Next comes capture API. If you're running Windows 11 version 24H2
Speaker A
or newer, select Windows graphics capture. It's faster, more efficient, and generally provides lower latency.
Speaker A
If you're still using Windows 10 or an older Windows 11 build, DXGI remains the safer choice. Then there's Q target.
Speaker A
This is one of the most overlooked settings inside lossless scaling. Think of it as your balance between responsiveness and stability.
Speaker A
Q target zero prioritizes the lowest possible latency. Perfect for competitive games where every millisecond matters.
Speaker A
Q target one offers the best overall balance and is ideal for most players. Q target two focuses on stabilizing performance during heavy GPU loads, although it does
Speaker A
introduce slightly more input delay. If you're unsure where to begin, start with Q target one and experiment from there.
Speaker A
Laptop users have a secret advantage. Here's something that surprises a lot of people. Gaming laptops can actually benefit from lossless scaling in a way many desktop systems can't.
Speaker A
On many laptops, the internal display isn't connected directly to the dedicated graphics card.
Speaker A
Instead, it's routed through the integrated GPU.
Speaker A
Normally, that's considered a limitation. With lossless scaling,
Speaker A
it can become an advantage. Your dedicated GPU focuses entirely on rendering the game's real frames.
Speaker A
Meanwhile, the integrated GPU takes care of generating the extra frames. Instead of one processor doing everything, the workload is shared.
Speaker A
The result is smoother gameplay and less pressure on the dedicated GPU.
Speaker A
There's one important limitation. This only works while gaming on your laptop's built-in
Speaker A
display. Most HDMI and DisplayPort outputs bypass the integrated GPU entirely,
Speaker A
meaning external monitors usually won't benefit from this behavior. If you're playing directly on the laptop screen though, it's absolutely worth taking advantage of.
Speaker A
Combining upscaling with frame generation. This is where everything starts coming together. Frame generation alone is impressive. Upscaling alone is also effective. Combining both is where lossless scaling really shines. Start by lowering your game's rendering resolution. For example, if you're
Speaker A
playing at 1080p, render the game internally at 720p. Then open lossless scaling.
Speaker A
Enable resize before scaling. Now choose the scaling preset that matches your hardware.
Speaker A
Around 1.3x gives you image quality close to native resolution.
Speaker A
1.5x offers an excellent balance between image quality and performance. 1.7x shifts further
Speaker A
toward higher FPS, and 2x prioritizes maximum performance if your hardware needs it.
Speaker A
Once the image has been rebuilt through scaling,
Speaker A
enable frame generation. If you're using fixed mode, consider locking your game's base FPS with
Speaker A
RTSS before enabling LSFG.
Speaker A
For example, locking the game at 45 FPS allows frame generation to produce an output close to 90 FPS
Speaker A
while maintaining excellent frame pacing.
