Can you provide more inf about crashes? How it happening? You said it happens during zones loading mostly, but what kind of crash is it? What your operating system telling you? What kind of error? How looks visual part of crash, for example "During loading area/objects/meshes the screen becomming black for a second and the game just closing without any promts like it was just stopped in the processes"... Or does it providing any crash information ? As far as i know there are bunch of problems and issues with Alienware Notebooks especially m15x & m17 which taking parts in graphical/3d work and games. Also i should say that almost all of Alienware products are strongly Overpriced. Also its just my opinion but doesn't Oblivion Unofficial Patch should go after better cities since its mostly fixing some bind meshes and textures? Same as RAEVWD... Also had you tryed to set Preload Size limit to lower numbers? mine usually is much lower then 50.000.000. My PC is kinda older technologically and based on Core Quad CPU, I got 8gb ram with cut FQ to 1066 instead of 1333, Radeon 5850. If not talking about out different GPUs, then our perfomance is about to be similar. So i dont think you need to set big preload number if your crashes happening right during loading screens and black screens changing zones, but if it happens when preload is over and you already see some parts of game world and have just minor freezing that means that system continue to load and then it can be: Some wrong order of mods of mesh collisions conflicts. Your GPU can't handle the colisions. As far as i know as i was reinstalling game over & over again b'cause of mods like Better Cities there are a lot of problems with spliting those mods in the right way & some times even need to manually edit/delete/replace some meshes to make everything to work fine. As far as i see you have moderate number of mods with World Mesh changing... for my opinion you should move all Better Cities, Cobl , Knights and mods of that kind infront of loading order for example to set Knights before Unofficial Shivering patch and some kind of other things. Check this http://wiki.tesnexus.com/index.php/Load_order_recommendations. if you had not check it already. only thing i think is wrong there is that USIP should goes only after Knights. But its just mine experiance. Also what texture resolution size, LODs, shadows and parameters of that kind you have set in your ini ? You said that other games/3ds hardly crashed ever, but that means that they had crashes? Same with it> you sould provide more inf. Sry for my bad english.
