Linux is all good if you only play singleplayer games. My friends started playing the finals yesterday and it doesn’t run on linux because of EAC. Windows can run all my games without any proton switching and all the nvidia features like ray reconstruction and pathtracing with frame generation just works (alan wake 2 looks so good).
The point is you can’t eat your cake and still have it afterward, because it has been eaten. So the more common version OP referenced makes no sense because you obviously need to have your cake before you’re able to eat it, so it’s unclear what you’re trying to say.
Can I have some cake?
Sure, here you go. You can go ahead and eat it, too. Go on. It’s chocolate.
*having cake and eating it, too.
Right, but then the cake is gone and you don’t have it anymore, you just have a plate with crumbs. That’s what the adage is trying to convey (you can’t have it both ways). Either you save your cake for later, or you eat it not, you can’t do both.
