the reason the game is crashing is because
while if you check in TASK MANAGER it shows about 1gb of ram being used
the game is a 32bit EXE naturally but the game gets allocated more ram then it uses,
the problem is on a 32bit OS at around 1.6-1.7gb of ram allocation the game with CTD,
on a 64bit OS at 1.9-1.95gb of ram allocation the game will CTD,
now again the game MIGHT only be using 1gb of ram but ram used and ram allocation are 2 different things.
now of course LAA on 32bit means 3gb allocation max 64bit OS LAA allows 4gb Allocation, that total allocation amount is key for keeping skyrim from crashing,
thats why LAA works it ups that high enough the game dosent trigger the crash to desktop.
its not overclocking, in fact Skyrim is 100% cpu limited for most of you, up your cpu clock speed even if you have to drop the # of cores down to 2, keep uping cpu speed, the game scales with clock speed
example 3ghz 2500k = example 50fps avg 30fps min
example 4ghz 2500k = example 60fps avg 40fps min
so overclocking the CPU is pretty much the only way to truly increase performance in Skyrim especially when increasing draw distances which my tweaks do by some rather extreme amounts,
CPU is so limited in fact even my 2500k at stock is hold me back 6950 sits at 65% usage pegged if i overclock cpu gpu usage goes up keep these things in mind,
that said for people that need a proper exe with LAA ill post a link momentarily to the original 1.1 exe thats LAA aware, essentially drag it drop it in your skyrim folder the new patch wont make a difference with this older exe so it fixes the issues for you. this is the exe straight from my game folder.
Also
no point getting the 11.11a drivers they make next to 0 difference and Crossfire support for Skyrim cannot be implemented via CAP, Skyrim will need a brand new driver period for Crossfire support, this means youll have to wait for 11.11b for Skyrim Crossfire support to function properly without glitches which is what happens when forcing crossfire via Radeon Pro, or exe renaming
