Is it possible to get a stable game work with high uGridsToL : V

» Wed May 30, 2012 8:55 am

Hi folks, sorry for my poor english. Finally got my skyrim work fine and use more than 2 gigs of RAM. Now it's always between 2.1 and 2.8 gigs (with high-res textures and higher quality meshes for LOD). But game could use 4 gb so i decided to use Skyrim at it's 100%. ugridstoload=9 now and game works perfect without any crashes. On my cheap pentium g850 i have 50-60 FPS at open areas (using SKSE). ugridstoload=11 rarely cause crashes, RAM usage is between 2.3-3 gigs, at 13 saved games sometimes don't load but if they do FPS count is about 30-40 (nearby solitude), 15 is not playable because game or crashes or won't load. Is there any way to fix it? I would be happy to get ugridstoload=13 work fine(no flickering mountain textures and game simply looks great)
