What’s the best noise suppression for streaming?

The one your GPU already paid for. RTX 2060 or better: NVIDIA Broadcast — free, unlimited, excellent. GTX card: the legacy RTX Voice build. No NVIDIA at all: OBS’s RNNoise filter for the stream plus Discord’s built-in Krisp toggle for comms. All $0.

Will noise suppression tank my FPS?

It costs something — AI filters share your GPU or CPU with the game. How much is rig-specific, which is why every GPU-touching guide here ships a 60-second measure-it-yourself benchmark instead of a made-up number.

Do I ever need to pay for this?

Rarely. The paid door exists for specific walls — cross-app cleanup beyond Discord, incoming-audio filtering on any app, a Mac — and the Krisp guide prices it honestly. Everything else on this site is free.

Noise suppression for streaming: pick your lane by GPU, pay $0

Your teammates can hear your keyboard. Not vibes-level hear it — clip-it-and-post-it hear it. The fix is a spec check, not a shopping trip: this category’s best tools are free, and the right one is decided by the GPU already in your rig.

The GPU router

IF: RTX 2060 or better

NVIDIA Broadcast

Free, unlimited, noise + room echo removal on tensor cores. The lane everyone else is jealous of. Costs frames — measure, don’t guess.

IF: GTX card

RTX Voice (legacy)

The patched old build NVIDIA keeps alive for GTX owners. Rougher, heavier, still free, still real.

IF: no NVIDIA at all

OBS RNNoise + Discord’s Krisp

RNNoise on the stream mic, the built-in Krisp toggle for comms, Sonar if you want a mixer. Zero dollars, zero NVIDIA required.

Frame budget — measure yours, 60 seconds

Every AI filter spends frames. Anyone quoting an exact FPS cost without your rig in hand is selling something — run the benchmark instead:

Pick a repeatable scene (same map spot, same settings) with an FPS overlay running.
Note average FPS for 30 seconds, filter OFF.
Toggle the filter ON. Same scene, 30 seconds, note it again.
The difference is your real cost. Re-check after driver updates.

your framesfilter cost = measured, not quoted

Community reports put modern-GPU costs in the low single digits and older RTX 2060-class cards higher — treat those as rumors with good intentions, not specs. Your overlay outranks every forum post, ours included.

House rules

Free first: if a $0 tool covers the job, the guide says so and stops. Frames counted: no invented benchmark numbers, ever — the 60-second protocol above ships on every GPU-touching page. Paths verified: every settings chip was walked against vendor docs on the build date stamped up top. And when paid software earns a mention — Krisp, for exactly three walls — the affiliate link is marked like it should be. Receipts on the legal page; the crew on about.
