Hi, has anyone noticed any improvments in FS9 running RC on the second core on a duel core chip? Would I benefit if I leave core 0 to FS9 only, and core 2 for RC, Activesky, AI Smooth?Thanks,Bill

I would try setting RC to core 2 because of its heavy processing collating communications. RC does not have a high impact itself on FS but rather the other way around. It is actually disk access that contributes to the issue but it could not hurt in my opinion to check it. I also suggest leaving AI Smooth with the core that FS is on due to its high interaction but low load on resources. I do not have a dual core but I am a tech and this would make sense to me.Just an estimate, but I am sure one of our dual core users might chime in.

May I ask you how that can be done please?

Search the AVSIM FS hardware forum under affinity.A utility for permanent changes is in this thread:http://forums.avsim.net/dcboard.php?az=sho...ing_type=searchMake a backup copy of RCV4.exe before you do this .exe modifying routine. You may need to do this each time RCV4.exe is updated.EDIT: The link to the utility article on tomshardware is here:http://www.tomshardware.com/2004/05/28/get...rocessing_buck/A disclaimer here that I/we can't be responsible for any nasty results. Make sure you back up a safe copy of anything you modify.I can not test this myself.
