P3D 5: How to get less GPU memory usage.

[robpol471]

Less GPU memory usage can be achieved by changing the max visibility configuration in ASP3D  and   LOD_RADIUS = 6.500000 in [TERRAIN] of Prepar3D.cfg.

P3D 5 loads hundreds of km at 360 ° and is found if for example we fly to FL300 with default clear sky but with an ASP3D weather engine, in reality the real visibility is considerably less and we can also decide what is the maximum visibility in flight in case of clear sky.

The test I did was to have changed the value of LOD_RADIUS = 3.500000 in [TERRAIN] of Prepar3D.cfg then P3D 5 has loaded less textures but more than enough to not have blurry textures with the 50 miles of max visibility configured on ASP3D - Options - Visibility options - Maximum surface visibility and Maximum upper.

In this example with LOD_RADIUS = 6.500000 and 75 miles on ASP3D at Orbx LIEO OLBIA I got 4.5 GB of GPU memory used:

With LOD_RADIUS = 3.500000 and 50 miles on ASP3D at Orbx LIEO OLBIA I get 3.8 GB of GPU memory used therefore 0.7 GB less:
