Oh dear.
I worked my ass through lots of tweaks and guides and bla and i finally got my skyrim stable with patch 1.3. No crashes, no more stress.
I just finished my exams at the university and started steam. And by the installation of an 16 MB Patch everything is [censored] up again. All the work and trouble night after night a month ago for nothing. Reinstalled steam, drivers, the game. Running it blank, running it on low, running it on high ress, everthings useless. All the tweaks from 1.3 didn't work.
Do anyone besides remember the time when you simple installed a game and it worked? Damn you Skyrim! Gemme back 1.3 -.-
Friend, Skyrim is dead-simple and easy to install. It works (reliably).
I get a CTD after maybe ~6 hours uninterrupted play... but there are tell-tale signs before crash.
Tweaks and guides and bla won't necessarily get the game running well!
It starts with your PC, and your ATI or nVidia control panel, before the game is even installed.
Set up your rig for games, #1. Clean, lean & mean.
Then set up your vidcard control panel (I use nVidia) with all high-performance or application-controlled settings.
Reboot.
Accept whatever settings the automatic thing recommends (ie. medium).
But change setting to your native resolution (1680 x 1050 or more probably 1920 x 1080) with no AntiAliasing.
I use no AA, 8x AF and the FXAA un-ticked.
If your PC is configured, maintained and solid, and meets the game spec, the latest v1.4.10.04 version should fire right up.
I have 800 hours on this game with the bone-stock default .ini file and no tweaks.
Native resolution, no AA. Looks fantastic, plays very well.
Overall this game is far friendlier and more solid than FO3/NV when first released...
But your problems are clearly specific to you. Complaints to Beth won't help.
I will help you if I am able. We can and will get the game running for you,
Regards
