Titanfall 2 Multiplayer Fix

Fixes the "Contacting Respawn Servers" connection issue on modern Intel CPUs (10th gen+).

Problem

Titanfall 2 fails to connect to multiplayer servers on modern Intel CPUs due to an OpenSSL bug with AVX-512/VAES instructions.

Solutions

This repo offers two options:

• Shim method (recommended): Uses a Windows Application Compatibility shim to set OPENSSL_ia32cap only for Titanfall2.exe.
• Launcher method: A small launcher that sets OPENSSL_ia32cap and starts the game.

Alternative: System-Wide Fix

You can also set the environment variable globally (affects all applications):

1. Press Windows key and type "edit the system environment variables"
2. Click "Environment Variables"
3. Under "System Variables", create new variable:
   • Name: OPENSSL_ia32cap
   • Value: ~0x200000200000000
4. Restart your computer

⚠️ This affects all OpenSSL applications system-wide. The shim method is recommended.

Usage

Choose a method:

• Shim method: see shim-method/README.md
• Launcher method: see launcher-method/README.md
