May I ask what's the benefit for you as a tweaker?

It's more a way to protect my investment (time and money) into something that is *supported* and where I can ask a developer a question and get an answer like Beau in the Prepar3D forums is doing.I also have my own add-ons for FSX, audio checklist module, a video recorder, custom shaders, a d3d wrapper for bloom effects a simconnect console app to inject objects etc etc, so should I keep developing this for FSX or into a platform that I know *IS* supported today?So, as a 'tweaker' there is no benefit, as a developer well.. I already answered that question.

Client licenses are $499. The price for the Prepar3d Developer Network (PDN) subscription is $9.95/month.Regards, Mike Mann

Mike, it is critical to note that a developer doesn't have to purchase the "Client license" at all. Only his/her "clients" would need that, assuming that the developer had any "clients" at all that is... :(

So let me get this right... BP=0 is now an "official" tweak?

You make it sound as if it was snake oil or something... ;)David Roch deserves the credit for making it 'official' even BEFORE Lockheed Martin :) trust your Avsim moderators...and the BP=0 research refers to 'all' the tweaks. Not just the BufferPools one. Check the Prepar3D help file on improving performance.

Maybe, maybe not... But I get excellent performance to begin with... My original understanding of the tweak was that it bypasses/defeats the resource management built in to the game which seemed counterproductive. I just assume Microsoft would have tested that case throughly but it obviously wasn't. However the only problem now seems to be that FSX might have a lot of code that depends on the current system staying intact. And unfortunately my experience with BP=0 is that it's slow to respond leaving black boxes. Either way I see the merit, so good work!
