Hey Mr. Jack. If you could attach your console log, that would help the people at FS diagnose your problem a little better. You can find those here at:

C:\Users\YOUR USER HERE\AppData\Roaming\Fatshark\Vermintide 2\console_logs

Unfortunately, your PC does not appear to meet the minimum requirements for Vermintide 2, which is resulting in the crashes you’re experiencing. The minimum requirements for Vermintide 2 are:

• Requires a 64-bit processor and operating system
• OS: 64-bit Windows 7, 64-bit Windows 8 (8.1) or 64-bit Windows 10
• Processor: Intel Core i5-2300 @ 2.80 GHz / AMD FX-4350 @ 4.2 GHz
• Memory: 6 GB RAM
• Graphics: NVIDIA GeForce GTX 460 or AMD Radeon HD 5870
• DirectX: Version 11
• Network: Broadband Internet connection
• Storage: 65 GB available space

In this situation we can only recommend that you submit a refund request via the Steam client. Apologies for any disappointment caused.
