Hey there guys,
Thanks for reaching out, I'm sorry to see many of you noting issues when launching the game!
As we have a mixture of reports and attempted steps, I'll layout some basic steps to try first.
Our system requirements can be found here, so please make sure your PC matches / exceeds these specs.
Now for some troubleshooting steps, please first ensure that you complete all of the steps listed in our PC troubleshooting guide.
If you've found that these issues have began recently, please also ensure you've tried verifying the game files (which is noted in the guide above anyway).
Should you experience full PC crashes / blue screens, please make sure you've given your PC a System File Check too.
There are a number of steps linked, which do often resolve many of these crashing and performance issues so please make sure you go through all of them.
Let us know how you get on and if you need any further support, please share your PC specs too (GPU, CPU, RAM, OS, Laptop / Desktop)!
