its possible with a newinstall from skyrim to update the game only to the official patch 1.4 and not further to 1.5?
i'll do all things i know to make skyrim better to play with 1.5 but nothing helped.

when give bethesda an update because the performance problems?

i deactivated anialiasing in skyrimprefs to eleminate some graphicbugs and testet every nforce driver since 270 to 296 for my graphic card, nothing will be better.

i'll go back to 1.4 but with steam i don't know how i can make that.

when its possible to go down to 1.4 can someone pls explain me an give an instruction?

thanks for answers

None of the platforms' "services" allow backpedaling. You might be able to use Windows' System Restore to revert.
