8-3.2ghz core mac pro, with Nvidia Quadro FX 5600 GPU wont run Unreal

I have an 8 core xeon 3.2ghz mac pro with 12 gig ram and 3TB of HD space spread over 4 drives. Im running OSX 10.11.6 and the the engine will not run on my system in mac OSX. However i also have a dual boot windows 10 running. Windows will load the program and start it ,but it crashes immediately and says im out of memory. I have a Nvidia Quadro FX 5600 GPU, running direct X12, none of my autodesk 3d applications have any trouble running, why wont unreal run? what gives?
Can I load an earlier version of Unreal, or buy another GPU card or something. I know that just because my software diagnostic says im running Direct X12, doesnt necessarily mean my card is running the correct drivers. BUT C’mon, geez man, my system may be a little older but it still has more hardware cores running faster and with more ram than most off the shelf new ones.

Can somebody help me solve this or should i just abandon Unreal Engine altogether and go back to using 3ds Max 2016?

You need a DX11 capable card, Quadro FX 5600 is a DX10 card which is Shader Model 4.0. Someone please correct me here if i’m wrong.

Apparently you can force the engine to run in DX10 mode with some of the bells and whistles trimmed out:

or should i just abandon Unreal Engine
altogether and go back to using 3ds
Max 2016?

How would that help? :smiley: Apples vs oranges and such.

Thanks, i figured it must be something like that. Even though the windows direct X diagnostic says its running Direct X 12, i was skeptical that the hardware would support it. While 3ds max is great for modeling assets, the lighting and particle effects are more involved and cumbersome, and dropping a large detailed mesh in from world machine, then animating it with all the caustic effects of bounced light and water, is just not feasible from a work flow point of view.

Of course i prefer to run Unreal in mac OSX if possible… i find that the system is more stable for higher resolution compositing and particle effects in software like Premier and After effects and of course Autodesk Smoke.
Since I am shooting for 4k resolution and hyper real cinema quality VR, naturally i want the engine as stable as possible.

Do you have any recommendations as to what card i should consider?

Thanks

Now that the bitcoin craze is over(ish), the prices have dropped in the last weeks quite significantly. It’s actually not a bad time to buy a video card:

  • the Radeon RX580 is hitting £250-300 or GeForce 1060
  • GeForce 1070 would be next tier at around £450 - a very future-proof choice
  • 1080ti if you have money to burn

I remember AE being somewhat crashy under Win7, haven’t worked with it recently, though.

Ordered the GeForce 1070 today. I found it new for $475 and was assured it would work in my mac pro, so i’m giving it a shot. I looked at the 1080Ti, nut im uncertain that my system would be able to use enough of its functionality to make it worth the price… Kind of afraid the GPU might bottle neck on the PCIe 2.0 architecture of my system.

I figured quadrupling my current GPU specs with the 1070 was enough for the time being…

I have been out of the loop for a few years, so Thank you for your help…
