The technical reason is that the game relies on Metal 3, and Metal 3 in turn relies on certain features of Apple Silicon GPUs, not the least of which is tile-based deferred rendering for acceptable performance. The GPUs in the overwhelming majority of Intel-based Macs use immediate-mode frame rendering; Intel only started supporting TBDR in 11th generation chip GPUs (which are not found in any Macs) and AMD only supports it in Vega GPUs, which are found in a very small subset of upgraded iMacs and Mac Pros.Why in the world is this not available also for Intel Macs?
