mac m1 series has serious graphics issues

[elise123]

I used m1max 64g with 32gpu , crossover preview and macos 15.2. I found that there is no graphic issue when i use --dx11 for the game to run. However, if i use --dx12, there is serious missing graphic effects like no trees, missing stones, which iu hard to play. I check the source code on mac and all others work ok for m2-m4 series. I think there is am api or dl lib wrong in the Unreal engine which make dx12 on mac did not show graphics, but dx11 did not use that dl so it work. Would you please check this issue and fix it? This one also happens on linux and windows conputer with some oldest amd gpu but did not happen on nivida gpu
