Does Xplane 11 make use of all core processors available when run on a Black Cylindrical Mac Pro?

asked Jun 19 by Nufmuff (12 points)
If I buy one of the new black "paper bin" style MacPro computers which vary between 6 to 12 cores, will XPlane11 (and 10) take advantage of all the core processing on offer, or will it just use up to e.g 4 processors.  I only ask because I made this mistake some years back with music software - buying an 8 processor machine and the software was only able to use a max of 2 processors.

Will I really notice much difference between a D500 and D700 graphics card?

Kind regards,

I'm not expert here, (only a user), but as far as I know, X-Plane does use all the Cores. The only problem is that the rendering is done with OpenGL that make the system (X-Plane) talk to the GPU with only one core. Making the things slow down. The GOOD NEW is that this going to change when Vulkan is finally implemented. The bad news is that this is going to take some time (maybe a year) for it to be done.

If you have time I recommend you do view this . It will give you some imformation.

Hi Andrew,

I am not associated with Laminar Research or any other company or organisation within the USA.  I live on the otherside of the world downunder and no expert like some others on X-Plane.

I am of the opinion you will get better value for your money if you buy a windows based PC whereby you will be able to upgrade far easier than you will with a Mac System.  Although X-Plane is developed on a Mac System, Laminar Research staff have indicated in a previous Q&A answer in this forum to go for a windows based PC.

As I understand X-Plane is currently based around a 4 core system to get the best result.  As ice_pdb has indicated more cores will or may be more beneficial in the future as X-Plane develops further.  I have seen another video elsewhere (can't find the link) using another operating system other than windows making mention of X-Plane only using 4 cores.

Have a look at the following youtube video produced by MIchael Brown from X-Force PC regarding using multi cored processors. This is the recommended company by Laminar Research for the supply of PCs in the USA.  The presentation is based on windows system but it has a message.

I am also of the opinion that your question has been asked on a previous occasion in the same forum.  To find the question(s) you will have to scroll back through the pages.

Hope this helps.
