Why is Parallels Desktop 16 dramatically worse than 15 in terms of game performance? For reference, my environment is listed below. MacBook Pro (15-inch, 2018) macOS 10.15.6 Processor :2.6 GHz 6core Intel Core i7 Memory: 16 GB 2400 MHz DDR4 GPU: Radeon RX 5700 XT 8 GB eGPU: Razer Core X Chroma Parallels Desktop 16 for Mac Home Edition Windows 10 Pro ver 2004 Build 19041.450 Upgrading the version to 16 makes the lag worse. If you downgrade to 15, there is some lag, but not as bad as with 16. If you check the Activity Monitor, the eGPU is working on both versions. Is this a lack of tuning for DX11 or Metal? If so, by what time will it be improved? Best regards.
