Add commandline to use DirectX 10

It will probably sound like a really dumb question.

My notebook is an old one with directx10, I installed UE yesterday and its always crashing at 95%, I found out that thats because of the directx and the way to fix that is by adding the -d3d10 commandline.

The problem is, I dont know how to do that, where do I put this code? is it on the shortcut? Sorry I know its a dumb question but Im new to those kind of things

I have very simillar problem with running packege on old laptop

go to the exe file, make a shortcut and in the shortcut’s properties at the target folder, Encase everything inside in " "s and put -d3d10 at the end,hope this helps
