MacOS M1 processors

Hello.

I'm using Unity to develop a game application that has been working for years on Macs. With the new M1 Macs, though, I notice an issue where some of our 3d models flicker specifically on M1 Macs only. Updated Unity versions don't seem to fix anything, and editing the shaders doesn't seem to cause any change either (I'm working with Unity 2020.3.5). In the Unity Editor on this computer, everything renders just fine; it's only in an actual build that it's a problem.

Does anyone have ideas on things I could try?

 

Verified that if compiled just for x64 the game runs well with no graphic issues on an M1 Mac. If compiled for both x64 and M1 in the Mac M1 version the graphics are corrupted. Thanks God I purchased and M1 Mac to verify these things.

 

Here two examples. Works perfectly when compiled with x64 only in an M1. Bad when compiling with the M1 version.

 

Sure right now, thanks.
