Any point using "AffinityMask" in P3D?

Recommended Posts

I got a 6 Core Xeon (X5670 Westmere-EP) Processor.

in FSX I used to set my AffinityMask=62 (leaving Core 0 free).

since then P3D had many performance improvements.

is there any point using the AffinityMask in P3D?

is there any added value on leaving "Core 0" free in P3D?

I had understood the point of leaving Core0 free was that was where Windows habitually ran. Thus forcing apps off that core enabled both to have more dedicated CPU tasking.


Strikes me that is valid theoretically with P3D as with any other app. Practice may of course be totally different....


To my eye P3D uses more cores more aggressively than FSX however this is a Mark1 eyeball observation not a tested conclusion. As such have been happy enough that P3D appears more CPU task allocating efficient than FSX. Maybe this could be further optimised by an AffinityMask.
