There are also improvements with 3D graphics using OpenGL, although Parallels told us that it's difficult to provide precise figures here as this can vary greatly from one application to another. Interestingly, M1 and Intel Macs show improvements in different areas, with M1 Macs improving performance for VMs running Windows 10 on ARM by around 30%, while VMs on Intel Macs benefit from faster network connections.
Good performance is essential when running Windows, or any other OS, as a virtual machine (VM) on your Mac, and Parallels claims that Parallels Desktop 17 includes a new display driver that improves performance for 2D graphics by up to 25%. Some Parallels users have also raised questions about Windows 11's use of TPM 2.0, but Parallels points out that a 'virtual TPM chip' was already available in previous versions, and this has now been updated to support Windows 11. Parallels Desktop includes a 'virtual TPM chip', making it ready for Windows 11.
