I have a little doubt.
I dont have much money to purchase a top pc, so… Vulkan will improve to increase
FPS number in game?
(a little?)

As I said before and in the talk, the slide compares the number of API calls to accomplish basic drawing tasks between the two APIs to illustrate how much less per-draw setup there is in Vulkan, where things are more prebuilt and direct. The test is in Airfoil-Maker because that’s the app that runs correctly in both right now.

A comparison of GPU power used for 3-d clouds would be totally meaningless. 3-d clouds are bottlenecked on ROP blending, which is a hardware resource. That’s good for comparisons between GPUs but won’t change at all between GL and Vulkan.

For some ego-shooter it may be more important, but I personally feel that smooth framerate and accurate simulation of systems is more important than than having some reflection in a window of some terminal building (for example).
I understand that you are freaks and you want to get everything out of the machine that you can get out of it. Also what surprised me is “The dark bar is the number of OpenGL API calls made to draw that frame in Airfoil-Maker; the light bar is the number of API calls made in Vulkan.”:
Why are you comparing 3D power for an application that does no 3D at all (Airfoil-Maker). My very old ATI Mach64 could also draw an impressive number of 2D-lines per second unter X11, but todays applications are typically not drawing 2D lines.
Why don’t you compare the frame-rate killer that is like “50% transparent clouds with sun reflections and shadows on clouds, body, and panel?
One thing I wonder (if you have the graphics power): The visualization of the flight model did not change much since X-Plane 8; is the current flight model and particle system flexible enough to show a “virtual wind channel” with particles following the flow of air around the body and wings? Basically the idea is that the particles flowing from the front (let’s say) are deflected by the forces that the flight model computes at specific locations (mostly wing sections)…

Hello Ben!,
Thank you for your reply.

The real lever doesn’t move by the action of the governor, like in the S-76, so additional coding have to be done in order to make it behave realistically. I think by default there should be a dataref for the lever manual fuel control and another daref for the fuel injected controlled by the governor/FCU (fuel control unit)/FADEC. Or more info in the Planemaker manual 😀 .
I’m trying to do the AS-365 N2/3 (have all the manuals for it) and I find it hard to do it just with default datarefs without coding (I’m rookie coding).

PS: English isn’t my language I hope you can understand what I mean.

That’s a new engine feature that Petr asks me for a lot.

I don’t understand what the issue is here with the datarefs…throttle has always controlled fuel in helicopter in X-Plane because the collective is a separate control. What use case do you have where this matters?

I was more hoping of a way to *add* vertices – these perpendicular cardboard cut-outs would be the next thing that lets down that close-up ground experience of GA airports.

I’m a helicopter fan, and I don’t see many helicopter friendly features. One that’s most annoying for me is the throttle in the S-76 (governor for helicopters) that moves the fuel control lever… this should be done by some other dataref instead of throttle ones. maybe introduce FCU or other datarefs?

Waiting for the next beta release!! I really like messing with betas 😀
