Hello All,Can anyone please help me with the following (see images). I am using Directx10 and would like to stay with it.1. rain problem2. flickering, shimmering taxi linesThank you for your help.Paul

1. Just the way it works2. A bug when running DX10.

You can use DX10, you just cant use DX10 Preview mode in FSX.

DX10 is crap. Why are you using it?

The void your seeing in DX10 rain is because of an incomplete shader file its not the way it works its just brokenthis was brought up by myself & fixed by Christian Buchner quite a while back back up your Microsoft Flight Simulator X\ShadersHLSL\misc\Rain40.fx file then open the orginal Rain40.fx with notepad and replace everything in it with the following code and save next time you run FSX it should notice the fixed shader file and recompile for you fixing the void
