I play an online game and I get extreme lag. I know for sure that there isn't a network problem or my hardware being weak or something. So I assume there is a software conflict, like some software (antivirus? backup? anything else?) access the files of the game and causes this problem.
How can I find it, instead of by trial and error, ie. disabling software and testing?
Is there a tool that will list all the processes that access particular files or a particular folder?
any other idea?
