Ok peeps, 8 Easy steps to stop 100% cpu useage...
Found a workaround for the issue about " multi-core " function. As some users have reported when this is ticked your cpu usage sits at 100% on 2 or more cores.
I've just found a possible way around this:-
1st " Tick the multi-core function " and start TS2012.
2nd When the menu screen appers leave it open and return to your desktop.
3rd Open task manager on the " Performance page " and you will see that your CPU useage has hit 100% on 2-6 of your cores. ( No of cores depends on your system)
4th Now open to the Processes page and at the top you should see " RailworksProc2.exe *32 ".
5th Near the bottom of this page you will see a button that says " Show processes from all users ", click on this! and the page will refresh showing you all the programs currently running.
6th Now, RIGHT CLICK on " RailworksProc2.exe *32 " and you will see another menu pop up. LEFT CLICK on " set affinity... ".
7th Ok nearly there, all your cores should already have blue ticks in the boxes! Just un-tick 1 box that " RailworksProc2.exe *32 " is using and hit OK. check " task manager " again,
Your cpu usage should now have dropped from 100% to a normal level over all your cores.
8th Ok last step... RIGHT CLICK on " RailworksProc2.exe *32 " and you will see another menu pop up. LEFT CLICK on " set affinity... " again and now select <All Processors> and hit OK.
It works Fine for me and i'm now getting >200fps on my setup and the cpu temps have dropped too.
Hope this helps and makes sense to you all and remember THIS ONLY WORKS FOR USERS WITH MULTI-CORE SYSTEMS..
P.S Dont blame me for anything that you do to your own system, its up to you!!!
Cheers Mick.
Oh and dont forget to enable the " use more that 2gb address " memory issue...
