In CS2, NVIDIA Reflex Low Latency has three options: Off, On, and On + Boost. Reflex On lowers latency for competitive players. On + Boost adds more latency reduction for supported hardware, but it may hurt performance on weaker GPUs. Here's what each setting does and who should use it.
| Setting | Description | Best For |
|---|---|---|
| Off | No latency reduction, higher input lag | Casual play or FSR use |
| On | Reduces latency slightly | Most competitive players |
| On + Boost | Maximum latency reduction on supported GPUs | High-end NVIDIA GPUs |
AMD players: This option is exclusive to NVIDIA GPUs.
How to Enable Reflex On in CS2
01
Open video settings
Go to the main menu and select 'Options' > 'Video' > 'Advanced'.
02
Find Reflex Low Latency
Scroll down to the 'NVIDIA' section and look for 'NVIDIA Reflex Low Latency'.
03
Choose On or On + Boost
Select 'On' for most setups or 'On + Boost' if you have a supported NVIDIA GPU and stable frame rates.
04
Restart CS2
Close and reopen the game for changes to take effect.
When to Leave Reflex Off
Leave Reflex Off if you're using FSR or have an AMD GPU. Reflex is only available on NVIDIA hardware and doesn't work with AMD. Also, if your frame rate is unstable or low, turning Reflex On or On + Boost can make performance worse.
Does Reflex On + Boost always improve my aim?+
No, Reflex reduces input latency but doesn't improve your skill. It helps you react faster, but only if your frame rate is stable.
Can Reflex make my game slower?+
Yes, if your GPU is already struggling, Reflex On + Boost can lower your frame rate. Start with Reflex On for a balance of latency and performance.
What if I have an NVIDIA GPU but don't see Reflex Low Latency?+
Make sure you're in the 'Advanced' section of the video settings and that you have the latest NVIDIA drivers installed.
Does Reflex work with FSR?+
No, Reflex and FSR are not compatible. If you're using FSR, keep Reflex set to Off.
Once your settings are stable and you're ready to test your aim, head over to retakes.gg. It runs CS2 retake servers in Europe with six ranked lobbies, live player counts, and shared leaderboards. Join from the site or connect via Discord or TeamSpeak for a competitive experience.
