Quest and MSAA 4x

I saw a developer video that says 4x MSAA is almost free and should be set to that.  However, in my game (Using LWRP), when I set 4X MSAA I get around 60fps and when it's off (disabled MSAA) I get the max 72 fps all the time.  Does this seem right?  Does 4X MSAA have a lot of cost to it on this hardware?

Thanks

    That seems about right. It's totally not free and depends on the amount of edges to be drawn (grass for example can be suuuper expensive)

    There was some tech talk from Oculus about MSAA and it's almost free on target hardware.

    This page a has some relevant info:

    TL/DR: There's definitely a fairly significant overhead, but as TimKay mentioned, it'll depend on what being drawn

    @atomic_elk - Ah, this is very helpful.  This is more inline with what I'm seeing.  I saw that tech talk where they suggested it was basically free -- I suppose that's a relative meaning :smile: Thanks for the clarification!
