We're working hard on additional optimizations, stability improvements, and other performance enhancements targeted at PS4. It's always a difficult chicken and egg scenario when it comes to a beta like this - we need a decently large base of diverse players to find crashes and performance problems at scale, but we also want to provide the best possible experience for those of you kind enough to take the founder pack plunge.
Everyone has a different comfort level for a founders pack beta, and we don't begrudge anyone who feels Spellbreak isn't yet ready for their money, but either way we promise we're working to make sure that the PS4 experience is one both you and Proletariat can be proud of. Thank you for taking a risk on us, and I hope we can meet your expectations very soon!
