We hear a lot of complaints from TF2 players getting errors whenever they try to join a Valve server. 

Most common reasons include outdated drivers or mods. But, how can you fix that? We’ve got the easiest ways for this TF2 problem for you for a fantastic game time. Let’s start!

Fix #1: Update Your Driver

Make sure your drivers are updated as much as possible. If this causes the problem, here’s how you can go about updating your device drivers:

  1. Launch the run dialog by pressing the Windows + R buttons together. 
  2. When the search box opens, input “devmgmt.msc,” then click “OK.”

  4. Right-click your graphics card list, then select “Update Drivers” under the context menu.

Other Possible Reasons Why TF2 Crashes While Connecting to a Valve Server

There are various reasons why TF2 crashes while joining a Valve server, but a huge contributing factor might be due to the sv_pure 1 system. This server is vulnerable to crashes on the model side (most common in Valve and Skial servers). 

You can deduce the offending models as the C-models for the Crusader’s Crossbow and Sniper Riffle. Removing those ones will likely be the best workaround for the crashes, at least for now.

Go to Valve and fix whatever bug is causing the issue since they don’t arise on non-sv_pure servers, which we recommend.
