High performance, low error-tolerance applications previously only available to Windows are a continuing lock-in, yes - that's part of why gpu drivers are such a big deal. There have been working comparability layers for the various hard-to-run on anything but Windows software appliances, but a major sticking point has been the GPU support (which keeps the software running well). I don't think this will be true forever though, graphics drivers continue to make strides in being more open, often to the benefit of the various organizations writing or purchasing the gpus/firmware/drivers.
