Rust frame generation, DLSS and FSR

Updated 2026-08-20 · Windows 10 / 11 · Rust

Frame generation promises nearly double the FPS by having the GPU insert computed frames between real ones. In Rust, where PvP comes down to reaction time, that boost has a price. Here is what the game itself offers, what you can add on top, and when it is actually worth it.

Upscaling and frame generation are different things

DLSS and FSR in upscaling mode render the frame at a lower resolution and reconstruct it to your screen resolution. Every frame is real, just cheaper: FPS goes up and input lag goes down with it. Frame generation inserts a computed frame between two real ones: the FPS counter nearly doubles, but the game still responds to your mouse at the real frame rate, plus a short wait for the next real frame.

Technology	What it does	Input lag	Where to enable
DLSS (upscaling)	Lower render resolution + reconstruction, NVIDIA RTX	Lower — more real frames	Rust graphics menu
FSR (upscaling)	Same idea, works on any GPU	Lower — more real frames	Rust graphics menu
AMD Fluid Motion Frames	Driver-level frame generation	Higher	AMD Adrenalin, Radeon RX 6000 and newer
NVIDIA Smooth Motion	Driver-level frame generation	Higher	NVIDIA App, recent GeForce RTX
Lossless Scaling	Frame generation on top of the game window	Higher	Separate app on Steam

Does Rust have built-in frame generation?

The Rust graphics menu offers upscaling — DLSS for NVIDIA RTX cards and FSR for everything else. That is the first thing to turn on: Quality mode barely changes the image, Performance mode gives weaker GPUs a real boost. At the time of writing Rust has no built-in frame generation — check the graphics menu after major updates. So frame generation comes from outside the game: the GPU driver or a separate app.

When frame generation helps

Your base FPS is already 50–60 or higher and you have a 120–165 Hz monitor: motion looks noticeably smoother.
Exploring, building, farming — where smoothness matters more than instant reaction.
Your GPU is not maxed out: frame generation needs spare GPU headroom.

When it hurts

Base FPS below 40: generated frames are built from too few real ones, so you get artifacts and a "jelly" feel on fast flicks.
PvP and raids: input lag goes up, recoil control and tracking feel sluggish.
Rust is CPU-bound (big bases, monuments, full servers): frame generation adds no real frames and does not remove stutters.

How to turn it on

Enable DLSS or FSR in Rust on Quality first and see whether that is enough.
AMD: Adrenalin → Gaming → Rust → AMD Fluid Motion Frames — on.
NVIDIA: NVIDIA App → Graphics → Rust → Smooth Motion, if your card supports it.
Lossless Scaling: start the app, pick frame generation and a hotkey, switch Rust to borderless windowed and press the hotkey in the game window.

Anti-cheat

DLSS and FSR are part of the game itself. AFMF and Smooth Motion run inside the GPU driver and do not hook into the Rust process. Lossless Scaling captures the finished window image rather than touching game code. Nobody except the Rust developers can give anti-cheat guarantees — keep that in mind.

Bottom line

For PvP, use DLSS or FSR on Quality and cap your FPS — real frames and lower input lag. Keep frame generation for peaceful play and for cases where your base is already 60+ FPS on a faster monitor.

FAQ

Does Rust have frame generation?

At the time of writing Rust has no built-in frame generation, only DLSS and FSR upscaling. You can add frame generation from outside: AFMF in the AMD driver, Smooth Motion in the NVIDIA App, or the Lossless Scaling app.

Does Rust support FSR?

Yes, FSR upscaling is available in the Rust graphics menu and works on AMD, Intel and NVIDIA cards. On NVIDIA RTX cards DLSS usually gives a cleaner image for the same boost.

Does frame generation add input lag?

Yes. The game reacts to your mouse at the real frame rate, and frame generation has to wait for the next real frame. You feel it in PvP, so for fights use upscaling without frame generation.

Why did FPS go up with frame generation but the game does not feel better?

The counter includes generated frames. If Rust is CPU-bound, the number of real frames is the same, and stutters around bases and monuments remain.
