You have to manually map HOTAS controls in Project Wingman. It's a bit of a pain, but considering how few buttons it uses, not that big of a problem. You will have to use a mouse to navigate the menus though, unfortunately. But it should work, I've used 2 different HOTAS with it.

As for performance, PW in general is far more demanding in VR than one might expect from a game like it, it's not the most well optimized for it. The biggest resource hog is shadows. If you really want to boost performance us the FSR mod/VRPerfkit. I play on a Pimax 8k X so vastly higher res than the Valve Index, but it legitimately boosted my performance by almost 40% using the ultra quality FSR prest.
