What NOVA changes for Counter-Strike 2, the launch options worth using and the ones to skip, and how to measure the difference on your own PC.
No FPS promise here: what CS2 gains depends on how your PC is set up today. NOVA shows what's holding it back, then measures before and after.
01Before you play: anti-cheat
If CS2 won't start, check these first. NOVA's Checkup reads each of them on your PC and tells you which one is off; switching them on happens in your BIOS or Windows Security, and NOVA shows the steps.

NOVA never runs inside a game, reads its memory or changes its program files. The optional controller and mouse overclock installs a signed USB driver; check the game's rules first. How NOVA stays out of games →
02What NOVA changes for CS2
These are in Tweaks, off until you switch them on. Each edits CS2's own settings file, only while the game is closed: the same change as its video menu, made for you. Your current value is backed up first; switch it off and it goes back.
in-game V-Sync off
B · Measured by one lab or tester
Turns off V-Sync in the game's own settings, which holds each frame until the next refresh and adds input lag. With G-SYNC, use NVIDIA's G-SYNC setup instead of in-game V-Sync. Close the game first.
Exactly what it changesIn cs2_video.txt for each Steam account (userdata\<account>\730\local\cfg\cs2_video.txt under the Steam folder named by HKCU\Software\Valve\Steam SteamPath), sets the existing "setting.mat_vsync" value to "0" (no line is added if it's missing). Nothing is changed while cs2.exe is running.
Plus everything that isn't game-specific: Windows, power, network and input settings, and Game Boost, which applies per-game settings each time CS2 runs and puts the PC back when you close it. Every tweak →
03Launch options, rated
Guides still pass these around. NOVA's Games page shows the same verdicts for CS2: Use, Your choice, Test (prove it on your PC) or Skip.
Option
Verdict
Why
+fps_max <refresh − 3>
Your choice
Caps the frame rate (the fps_max console command). With a G-SYNC or FreeSync monitor, a cap a few frames under the refresh rate keeps every frame inside its range; with NVIDIA Reflex and V-Sync on, Reflex caps by itself. 0 removes the cap.
-allow_third_party_software
Your choice
Lets capture and overlay tools hook the game (some OBS game-capture setups, NVIDIA filters) by turning off Trusted Mode. Valve lowers your Trust Factor with it, so only use it if a tool you need doesn't work.
-high
Test
Starts the game at High CPU priority, the same as NOVA's per-game option. No lab has measured a gain; prove it on your PC before keeping it.
-novid
Skip
CS2 opens without Valve's intro, so there's nothing to skip.
-tickrate 128
Skip
Only affects servers you host yourself. Matchmaking servers run CS2's sub-tick at their own rate.
-threads
Skip
The engine picks its own thread count; no measured gain from setting one.
04Measure it on your PC
Benchmark › Proof mode runs the same test before and after a change and tells you whether the difference is real or within the noise, including when it made none.
The in-game overlay shows FPS and frame time in a corner of CS2, drawn in its own window, without touching the game.
History lists every change NOVA made, with undo for each, or Revert all.
