Q:I'm getting a lot of crashes, how do I stop this? A: In the launcher enable 'load textures on demand', also try 'force single threading'. Alternatively try unticking sound variation and disabling music.
Q: My cursor is stuttering a lot, how do I solve this? A: Try limiting your fps in the launcher (note that this can increase game startup time). Also try rolling back your nvidia drivers.
