I mean, I’ve been playing about 100 hours of Baldur’s Gate 3 on my M1 MacBook Pro, on the ultra preset. It runs just fine, and the machine barely gets hot while being nearly quiet. In fact, it is a very pleasant gaming experience!
Could the game run better on a dedicated gaming PC? Sure! Does it need to? Nah, not for me. The fact that I can play on the couch while my SO watches something else is worth a lot more than some extra FPS, to me.

Instant ram tar compression. What else?

RAM is commonly compressed on MacOS. My Mac is only using 8GB right now and a fair bit of that is cached files… which is kinda pointless since the SSD is plenty fast enough.

If you compress the ram, you need to push data through the cpu, which would tank performance. The whole idea of ram is to have a bit of fast space to store stuff, so it can be used for things that need to run fast and also require a lot of data. To get the performance to be as good as it is, a lot of times the cpu is completely bypassed, to prevent bottlenecks. If you don’t need it fast, just park it on the hard drive, there is plenty of space there. The memory manager takes care of that for you, with for example a technique called swapping.
These days there are lots of complicated technologies that achieve this goal, but it all started with DMA or Direct Memory Access back in the days.
Fun fact, in the 80s and 90s memory was so expensive and modern techniques like swapping were in their infancy it could sometimes be useful to compress data in memory. I used to use QEMM back in the days which had that feature, even though I didn’t use that specific feature myself.
In principle someone could make a memory chip that was capable of on the fly compression. But that would cause wildly inconsistent memory timings, which isn’t ideal and I don’t think the costs would level out versus simply getting more memory.

ZRAM/ZSWAP is a thing on Linux at least. But that doesn’t compress actively used RAM. That’s just compressed swap space in memory.

Which is basically how conpressed memory works anyway.
