For two years now, I have been having problems such as described in this thread.I have had to play on the lowest setting with no trees, no shadows, no shaders, still I would get freezes and sometimes crashes. This despite having bought 2020 iMac (3.8 GHz 8-Core Intel Core i7, AMD Radeon Pro 5700 8 GB, 64 GB 2667 MHz DDR4) stillI have got freezes and crashes on ALL my CM games. (RT, BN, FB, FI, CW, SF2, BS) Well yesterday, I updated the OS to Ventura from Monterrey. So far … I can play on highest settings with all the bells and whistles turn on, no freezes or crashes!
