(Sorry for mistakes, english is not my native language) Hi there, 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 8.00GB RAM Intel HD Graphics Family (Integrated) NVIDIA GeForce GT 540M 500GB HDD 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 Mango
