(Sorry for mistakes, english is not my native language)
I figured out that the following issues are caused by the d3d9.dll that comes with mods like ENB or Enhanced Skies.
To help improve fixing this problem, here's my system:
Acer Aspire 5750g (Notebook)
Intel Core i5-2430M 2.40GHz
Intel HD Graphics Family (Integrated)
NVIDIA GeForce GT 540M
Windows 7 Ultimate - 64bit
My Fallout 3 Version:
Fallout 3 - Game of the Year Edition - German
Patched to 1.7
Clean version, no mods.
So here's the problem:
When I start the game using the fallout launcher or the mod manager launcher everything is perfect. In the game settings my NVIDIA videocard is always selected (and i cannot change it, which i like, so it always uses the good videocard)
But as soon as I install mods like ENB or Enhanced skies (which i really want to play with) those launchers automatically select the crappy integrated Intel videocard which is absolutely useless to play games with.
And even if I try to start the game with the Intel videocard just to look if the mod is working, it crashes as soon as i load the game.
I realized that the d3d9.dll is causing these issues beacuse if i delete this file the game launchers select my NVIDIA card again, just like before, and everything works - except the mod of course which obviously needs the d3d9.dll.
I have no idea why it has to be like this. It's f**kin annoying.
Well i tried to deactivate the integrated Intel videocard, so that my notebook only uses the nvidia, but that ended up in my notebook not "turning on" the display at all.
I also tried to force run the game with the nvidia card, but this doesn't work either.
I hope those information are good enough to help me solve this problem.
Thanks in advance
