Yes, that gives it permission to use both cores, but it doesn't use them efectively. The program itself needs to be programmed to use 2 cores to use them to their full potential.
The good thing about multi-core support in rF2 will be that they could use a seperate core for complex tasks.
For example;
Core 1; main game running
Core 2; physics engine
This way they are totally independent to each other and can actually benefit.
The old multi-core support is just balancing the load over 2 cpu's which is no benefit on most systems.
The question will be if rF will effectively support 2, 4 or even the not yet released 8 cores.
i'm no expert but i remember reading something that games could never use the full potential of the dual core technology since games only run one process, so in order for rFactor 2 to use the dual core to its full potential he would have to run 2 or more process, would that also mean that on a none dual core pc the game would actually run slower ? like i said i'm no expert
I don't think rFactor 2 will run effectively without a dual-core processor anyway. This is 2009 baby!
On the subject of having difficulty with the processes, Football Manager 2009 runs on both cores (not all the time though), but only has one process, fm.exe.
