hi all!!!

i instaled this game, but i cann't play it because it is PROBLEM with "page file size"
it is 1GB en this game need 2 gb...

what is "page file" and how i can rise it?

As I understand it is "page file" a part of the hard drive which is used in the same way as RAM.

Me to had technical problems with Stalker and therefore red about these things, althought I have not tried to change my page pole size myself. Therefore I can not provide much help. What I can do is to point out a few links with USEFUL INFORMATION.

This link contain Information about virtual memory in Windows XP: http://aumha.org/win5/a/xpvm.php

This link TELLS more about the same and have instructions about how to optimise the page pole size:

For more information about this, which also is easy to understand I recomend reading about Memory Optimization in Koroush Ghazi´s TweakGuides Tweaking Companion which can be FOUND at http://www.tweakguides.com/

There is also some short instructions about how to increase the page pole size at the official stalker forums. Check "step #10" in this guide about how to eleminate stutter in Stalker, it gives short instructions about how to increase the size of the pagefile, but I recommend to first read througth the information in the links above to know exactly what these changes does:
