Counter-Strike 2 and NVIDIA Profile Inspector: latency first
For CS2, turn on NVIDIA Reflex in the game. With Reflex on, the driver's Low Latency Mode should add little, because NVIDIA's own guidance puts the game's integration first, though we could not measure it. Use NPI for a frame cap that matches your setup, a few FPS under refresh with G-SYNC and a high value without. NVIDIA already ships an 18-setting Counter-Strike 2 profile, and we have no evidence that other popular config tweaks help.
What NVIDIA already sets for CS2
NVIDIA’s profile for the game carries 18 settings, listed here from the driver package. Most are internal driver values with no public name, and the named ones include a ReBAR mode and a Smooth Motion API list. LAB · driver 621.14

Reflex, Low Latency Mode and pre-rendered frames
We have no GPU and no latency analyser, so this page has no latency chart. CS2 supports NVIDIA Reflex, which the game controls. NVIDIA’s latency guide covers when the driver’s Low Latency Mode applies. A player thread on r/GlobalOffensive argues against Reflex in CS2, and we found no test that supports either side. COMMUNITY · r/GlobalOffensive Try both in the game and judge by feel and by a tool such as FrameView.
Capping FPS at 240, 360 and 500 Hz
| Your setup | Approach | Source |
|---|---|---|
| G-SYNC monitor | Cap a few FPS under the refresh rate, with V-Sync on in the driver | Blur Busters G-SYNC 101 |
| No G-SYNC | Uncapped, or a cap above the refresh rate that your CPU holds steadily | Our judgement, not measured |
| Using a limiter | In-game or driver, not both | Wccftech CapFrameX test, see the limiter page |
Use the frame cap calculator for the number, and the frame rate limiter page for the steps.
Visibility tweaks: sharpening, texture filtering, Digital Vibrance
NPI can change texture filtering quality and anisotropic filtering, see texture filtering and LOD bias. It does not change Digital Vibrance. Anything that makes enemies easier to see by lowering detail is a fairness question. We did not capture before and after images.
Recipe
We give no downloadable file for CS2. The rows worth considering are Frame Rate Limiter V3, set from the calculator, and Vertical Sync with G-SYNC mode, as in the G-SYNC recipe. Attach cs2.exe, found under the game’s game\bin\win64 folder, to NVIDIA’s existing profile. We list the exe from the driver package.
Vulkan or DirectX 11
The games database lists both APIs, and Vulkan has been reported as a launch option. We could not check whether it is available today. Which driver settings apply to which API differs, so check each row’s effect in the game.
VAC and NPI
Undo
Set the rows you changed back to their previous values or use the row reset, then confirm in NPI. Undo and reset has the steps.
Questions people ask
Should I use Low Latency Mode Ultra in CS2?
Use Reflex in the game's video settings first. We could not test the driver mode together with Reflex, so we do not claim a gain from stacking them.
What is the best FPS cap for CS2 on 240 Hz?
With G-SYNC, a few FPS under 240, which our frame cap calculator gives. Without G-SYNC, many players leave the game uncapped. We have no measurements.
Does NPI increase FPS in CS2?
Not reliably. CS2 is usually limited by the CPU, and NVIDIA's profile already sets 18 values.
Is NVIDIA Profile Inspector VAC-safe?
Valve has published no statement about driver profiles that we found. A profile change is not a game file, but nobody can promise a tool is safe.
Can NPI change Digital Vibrance?
No. It is a display setting in the NVIDIA App, not a profile setting that NPI lists in its common view.
