KaidonniThanks for the very detailed answer.

First of all, files order look alright, yes, there are two scripts folders, one inside gamedata (as a main scripts folder ending with .script) and also another of scripts folder in config folder, contents of which this time end with .ltx. It's OK.
Secondly, you should not have a CTD when you're searching a body in Cordon. There is something wrong with either with the structure of your game from the beginning, initiated with a underlying defect possibly (like a symptom called "cold game" ) or -as you point out to the matter which hadn't known before- uninstallation of OL might have caused a problem as you say that it has done someone else, on this point I cannot make any comments as really I do not know this matter; but may need to be kept in mind.
Also, you are using 1.0005 STALKER, and although there comes a 1.0005 compatibility patch with the mod, however it has not been extensively tested as it has been done with 1.0004, as the mod originally based on 1.0004 STALKER. having said that, I haven't heard any such similar problems from people who are playing the 1.0005 patched mod. Particularly Cordon has never seen such a (particularly repeated examples of) crashes before.
Frankly, that example you gave on OL uninstallation sounds a bit worrying to me, and when I now heard of it, I should recommend a full reinstallation of STALKER, but before that, you can try to restart the mod, by deleting the gamedata folder and reinstalling the game, however if you have the same problem then toy may need to reinstall STALKER, so it's your decision of course.
Also, a last moment thought: I remember that you said you started your mod on a 1.0005 STALKER without putting the 1.0005 compatibility patch at the start, then you noticed and added the patch. Well, due to that reason there might have been some problem developed in the game (starting as 1.0004 mod on 1.0005 STALKER) and this may be the fallouts of that problem. So, a reinstalltion of the mod with inclusion of 1.0005 patch before the start, may resolve the problem without necessitating the re-installation of STALKER. Hope things go well. Please do tell us how they went.
Grump642Ye I've got a very significant increase in performance, in general, after putting the Quad-Core, but the problem is -as I have heard it before- is the late spawning of things, NPCs, items, start of the events. Yes, GSC optimised the STALKER for dual core with 1.0004 patch, but they haven't done it for Quads and I suspect that they will ever do that. So, for those who use Quad Cores, there is a problem here.
Unless there is a workaround for this optimization problem (which is now causing late spawns) from the masters like
NatVac and others, we the Quad_Core users are a bit doomed, as it seems.
Not software solutions, but as of seen in my experience, a short-term workaorund (which I'm not sure how effective in the whole of the things) is to wait a minute or two upon the entry a new level, and
save and reload in order to kick start (so to speak)
the delayed spawns in delayed cores of Quad.
For example, after you've spoken with Max in AW, the initial stage of the heli/APC battle starts which later turn to the Actor/Freedomers.
This takes about 30 seconds to activate as normal (I need to move one of the APCs, I remembered, too close to Max group, they're wasted as collateral damage).
It was like that when I was using my old dual core, but
now the event takes long minutes to initiate under the Quad_Core. (I haven't changed even a single thing, sequence as same as it was in
dual core testing).
But, the strange thing, when
I reload (either due to dying there or not) and
play the same mission again, then this time they come as it was supposed to,
no delays, nothing,
everything works OK. So
saving and reloading in the level seems to be
kick starting those delayed events, spawns under the
Quad-Core (same goes for the empty stash boxes which are otherwise full -reload and te items are in front of you)
I need to write some guidance for Quad_Core users with the release.
(PS: I've put the CS nightvison in the game, thanks
