As I don’t need “killer” precision on depth, I may just change for 1-(z/w) which seems enough.
I have also read on nvidia there is a trick: reversing near and farplane. I’ll investigate into this.
This one is also interesting (I think this is already in the bookmarks 🔗 Useful MonoGame Related Links U-MG-RL, I’m pretty sure I saw mynameismjp.wordpress.com somewhere posted by @kosmonautgames)
