Counter-Strike 2 (CS2) has taken the gaming world by storm, offering an upgraded experience from its predecessor, CS:GO.
With new features like dynamic smoke grenades, a revamped CS Rating system, and sub-tick updates for enhanced responsiveness, the game promises a thrilling experience.
However, the “VAC was unable to verify your game session” error has been a persistent issue for many players.
The Valve Anti-Cheat (VAC) system is designed to detect cheats installed on users’ computers.
If you’re encountering the “VAC was unable to verify your game session” error, it’s crucial to understand that this is often a temporary issue, usually triggered by game updates or file corruption.
In this comprehensive guide, we will walk you through the most effective methods to resolve this error and get you back into the game.
How To Fix “VAC Was Unable To Verify Your Game Session” In CS2
1. Verifying The Integrity Of Game Files
The first and most straightforward method to resolve this issue is by verifying the integrity of your game files. Here’s how:
- Navigate to Your Steam Library: Open your Steam application and go to your library.
- Access Counter-Strike Properties: Right-click on Counter-Strike 2 and select ‘Properties.’
- Go to Installed Files: In the Properties window, navigate to the ‘Installed Files’ tab.
- Verify Integrity: Click on ‘Verify integrity of game files.’
This action will prompt Steam to check all your game files and replace any that are missing or corrupted. Once the process is complete, restart CS2 and check if the issue persists.
2. Enabling/Disabling Administrator Mode
Sometimes, running the game as an administrator can resolve compatibility issues. Here’s how to toggle this setting:
- Navigate to Your Steam Library: As before, open your Steam library.
- Access Counter-Strike Properties: Right-click on Counter-Strike 2 and select ‘Properties.’
- Browse Installed Files: In the Properties window, go to the ‘Installed Files’ tab and click ‘Browse.’
- Locate the Counter-Strike App: Right-click on the Counter-Strike 2 application.
- Compatibility Settings: Go to ‘Properties’ and then the ‘Compatibility’ tab.
- Toggle Admin Mode: Tick or untick the box that says ‘Run this program as an administrator.’
After making this change, relaunch the game to see if the error has been resolved.
3. Check Your Launch Options
The error message also suggests verifying your launch options. To do this:
- Right-click on Counter-Strike 2 in your Steam library and choose ‘Properties.’
- Find the ‘General’ tab and look for ‘Set Launch Options.’
- Make sure there are no incorrect commands; if in doubt, clear the box.
4. Launching The Game Directly From Steam Library
Another method to bypass this issue is to launch the game directly from your Steam library, rather than using any desktop shortcuts or third-party launchers.
Simply open Steam, go to your library, and double-click on Counter-Strike 2 to launch it.
It’s worth noting that VAC errors can sometimes be temporary and may be caused by recent updates to the game.
If none of the above methods work, it may be necessary to wait for a new CS2 update that addresses the issue.
