Key takeaways
- Because a generated frame must wait for the next real frame to exist, the technology adds a little latency.
- Your inputs still register at the real frame rate, so 120 generated fps feels less responsive than 120 native fps.
- Latency-reduction tech like NVIDIA Reflex or AMD Anti-Lag helps offset this, and enabling it is strongly recommended.
What's inside
Frame generation is one of the biggest and most debated features in modern gaming. In short, it uses AI to create entirely new frames between the ones your GPU actually renders, inflating your on-screen frame rate well beyond what the hardware draws natively. A game running at 60 real frames per second can display 120 or more, making motion look dramatically smoother.
But there is a catch involving input lag and image artifacts that means frame generation is not a free lunch. This guide explains how it works, when to use it, and when to leave it off, so you can decide whether the smoother picture is worth the trade-offs in your favorite games.

How Frame Generation Works
Your GPU renders two real frames, then an algorithm analyzes the motion between them and inserts a synthetic frame in the middle. NVIDIA calls its version DLSS Frame Generation, AMD has FSR Frame Generation, and Intel offers XeSS-based frame insertion. The result is a higher displayed frame rate from the same amount of true rendering work.
The Input Lag Trade-Off
- Because a generated frame must wait for the next real frame to exist, the technology adds a little latency.
- Your inputs still register at the real frame rate, so 120 generated fps feels less responsive than 120 native fps.
- Latency-reduction tech like NVIDIA Reflex or AMD Anti-Lag helps offset this, and enabling it is strongly recommended.
When to Use It
Frame generation shines in single-player and visually rich games, such as open-world RPGs and cinematic titles, where smoothness matters more than millisecond reactions. If a demanding game already runs at a solid 50-60 base fps, generation pushes it to a buttery 100+ that looks fantastic on a high-refresh monitor.
When to Avoid It
Skip it in competitive shooters and anything where reaction time wins, since the added latency can cost you. Also avoid turning it on when your base frame rate is already low; generating frames from a shaky 30 fps foundation produces noticeable artifacts and a floaty, disconnected feel rather than a genuine improvement.
Tips
- Always pair frame generation with Reflex or Anti-Lag to keep latency in check.
- Aim for a base of at least 50-60 fps before enabling it for the best results.
- Use it on single-player games and turn it off for ranked competitive play.
- Combine it with upscaling (DLSS/FSR) to raise the base frame rate first, then generate on top.
Frequently Asked Questions
Does frame generation increase input lag?
Yes, slightly, because a generated frame waits on the next real one. Latency features like Reflex minimize the effect, but it never feels as responsive as the same frame rate rendered natively.
Is frame generation the same as upscaling?
No. Upscaling (DLSS/FSR) renders at a lower resolution and intelligently sharpens it to raise the base frame rate. Frame generation inserts entirely new frames between rendered ones. They are often used together.
Do I need a specific GPU for it?
It depends on the version. NVIDIA’s DLSS Frame Generation requires newer RTX cards, while AMD’s FSR Frame Generation is more hardware-agnostic and works across a wider range of GPUs.
Will it make a low frame rate feel good?
Not really. Generating frames from a base below about 40 fps produces artifacts and a floaty feel. It is a smoothness multiplier for already-decent frame rates, not a rescue for weak ones.
Conclusion
Frame generation is a powerful tool when used in the right place: it turns a solid base frame rate into gorgeous high-refresh smoothness for single-player and cinematic games. Just keep your expectations grounded, pair it with a latency reducer, start from at least 50-60 base fps, and leave it off for competitive titles where responsiveness beats visual fluidity.
