Speculations, Rumors, Wishes… [Topic Unique] – Page : 897 – Apple

Why couldn’t the MX have egpu like the intel? This limitation is a bit weird and seems artificial to me. They should work on this for TB Macs in particular

We also wonder why Apple doesn’t make a system like Proton

Unified memory prevents this, and external interfaces like Thunderbolt are really bottlenecks in this case. Already with non-unified systems like Intel, the loan can be significant.

Otherwise, Apple GPUs are not designed to manage dedicated memory, and AMD and Nvidia are not going to develop drivers for a niche of this type, too.

And Proton on Macs is complicated: the principle of Proton is not to emulate, but to replace calls to DirectX with calls to Vulkan (for example). But you can’t just do that, since the game code is only x86, so you have to use CPU emulation which causes big losses, especially since in games, you can’t take advantage of just-in-time compilation.

what I meant is that it’s DIY adaptations for the apple silicon versions

It makes no sense as a reflection. The vast majority of games on the market are offered on several platforms. An Apple Silicon port is no more DIY than when Sony ports a PlayStation game to PC or when something comes out on XBox, PS5, PC and Switch at the same time. This is a classic process in development. It generally happens later on Mac because it’s a niche market so the devs do the porting afterwards, but there are games that were released directly on Mac like Lies of P.
