Hi friends, im ramón from spain, i apologize for my por english. well ill try to give all the info i have to everyone can help me. the problem is: when i arrive to Whiterun, i got a CTD with no warning message im pretty sure that the problem is not Whiterun itself, but its the first complex cell i arrive after game start, so maybe is another issue. ive noted that when i arrive to 2300 kb of vram, game goes to a CTD, i have no problems before, as i told, in Riverwood, i never reach the 2300kb limit. still im not sure the problem was Whiterun, or the Vram, only writing my toughts. well going to describe my computer: Operating System: Windows 8 Enterprise x64 Amd Athlon II X2 250 (3000.0 MHZ) Motherboard: Asus M5A578L-M LX V2 (AMD RS880 + SB750) Mem: 8GB Graphic Card: ATI Radeon HD 5770 1GB GDDR5 Mods Instaled: (a note for that... THESE are the mods i want, the mods i think make Skyrim amazing, if i need to quit a lot of mods, i prefer not to play cos i want to play SKYRIM, not skyrim. :)) by other way, ALL TEXTURES, are reduced to 1024. Using Shadows low (distance of detail middle but graas to máximum), using ENB Cinematic Mod, and -Elys- Meminfo to check all data. and now... skyrym.INI: skyrimprefs: boss list: im playing via Mod Organizer. hope all info helps, please help masters of optimization. thx in advance.
