Found a way to improve performance and add Active Sky 16 weather radar... To substitute the original "vertical speed indicator", which has a huge performance hit add the following modifications to the "panel.cfg":

In the [VCockpit02], place \\ in front of "gauge10=Captain_Sim.x737.sys!L14, 8, 10, 500,500" and add the line "gauge10=KingAir!Vsi, -90, 945, 690, 700"

Like this:

//gauge10=Captain_Sim.x737.sys!L14, 8, 10, 500,500
gauge10=KingAir!Vsi, -90, 945, 690, 700

In the [VCockpit03], place \\ in front of "gauge09=Captain_Sim.x737.sys!R14,  1026, 1026, 500,500" and add the line "gauge10=KingAir!Vsi, 920, 940, 690, 700

Like this:

//gauge09=Captain_Sim.x737.sys!R14,  1026, 1026, 500,500
gauge09=KingAir!Vsi, 920, 940, 690, 700

You will lose the TCAS function and your "8" will become a bit weird in the altimiter, but anyway your performance will greatly improve...

Another performance hit is the original "weather radar"... Substitute it for the "Active Sky 16" weather radar... Read and download the file in the following topic: https://www.avsim.com/forums/topic/512672-wx-radar-gauge-x64-for-as16asp4-and-p3...

Than modify your panel.cfg to this:

[VCockpit11]
size_mm=1024,1024
pixel_size=1024,1024
texture=$WXSP
background_color=0,0,0
//gauge00=Captain_Sim.x737.wxr!wr_display, 0, 500, 305, 225
gauge00=RolasnRadar!ORadGauge, 0,500,305,225, sweep|beam|icing
