#1: DirectX always had a problem with the number of "dynamic" lights one could use at any one given time, I believe it's only 6 or 8?
Fpsc never could get one than one or two to light at once, really don't know why? Just stick with static lights if possible? Only use dynamic
when needed.
#2: Fpsc should work just fine on window 10? Is it not working for you? You may be missing some needed .dll files to run properly.
Did you follow S4Real's instructions for using Win10 with Black Ice mod?
#3: The prop_norm_spec_alpha.fx works just fine if you include the needed textures for the shader. Check/open the shader file and see what textures are needed.
Make sure they are there.
My games never have bugs. They just develop random features..
Lots and lots of random features...
