How to play sims 4 on mac m1 windows#
For applications where both the GPU and CPU are used (many MMOs, including World of Warcraft fit this criteria), data has to be copied into both partitions on the Windows side, then the changes reconciled before any output is carried out.

With the M1, Apple has granted full access to the entire memory address space to both the CPU and GPU cores. This is why Intel's use of the term "UMA" is misleading at best. Furthermore, data written to the system partition can only be accessed by the CPU, and data written to the GPU partition only accessible by the iGPU. So an HP or Dell laptop that ships with 8GB of RAM will only have between 6 and 7.5GB of RAM available for programs because the rest is allocated solely to the iGPU. With Intel iGPUs, the RAM is split into two virtual partitions: one that is used as system RAM, the other is dedicated to the iGPU. Apple simply has much more capable memory controllers (and also desktop-level GPU cache sizes) - they optimize for performance and efficiency here and not cost like other vendors. Their memory topology is practically identical to Apple's (CPU and GPU access memory via a shared last level cache). Intel (and AMD) iGPUs have been using UMA for years. So you still have to copy the data, it's just the copy itself is much faster (you get full 68+GBps bandwidth instead of 15GBps of PCI-e 3.0 16x used in high-end gaming GPUs) Zero-copy functionality requires explicit use of specialized APIs and needs you to set up your data in very particular way. Just the fact that you have UMA does not mean that you don't have to copy the data. The overwhelming majority of games use the CPU as a staging area for setting up resources that are then copied and used on the GPU. UMA is much less important for games (than say, for content creation software), because it is very rare for games to require both CPU and GPU access to the data.
