Many Unreal/Unity based projects, such as Carla and Airsim and CoppeliaRobotics based projects, ROS2. Those are used for simulation and research. Many are on board with Nvidia now and their Omniverse. Spoke to some game developers during GTC, same there. Blizzard is probably the most discussed here in the forum. You'll find this trend pretty much anywhere in the field of AI and autonomous systems (cars, drones, robots). Audi, Volvo, Continental, Toyota, Honda, Kuka, ABB, the list goes on. This started when Apple abandoned Nvidia and only got worse over time and much worse with the release of the M1 systems. Look at Apples Tensorflow fork... it's a mess. Look further, PyTorch, Matlab, ... even Apple is using Linux for their AI research. Visit a world leading conference, then try to reproduce the results of the authors.
Won't matter to the end user browsing the web and writing emails, but macOS had a large chunk of the scientific research market (except for clusters) in the past few years and that market is shrinking rapidly. Part of this is due to Nvidia offering software no other company has in this field. But part of it is Apple locking down their eco system further and further.
