- mtgx 14y agoWhy? Aren't 64 bit versions supposed to be even faster?
- singular 14y agoI wonder whether larger pointers could result in being able to cache less media. But that's a wild guess.
- tene 14y agoIf they use the X32 ABI, that won't be a problem.
- singular 14y agoAh yes of course. But if so, wouldn't they have issues interacting with the driver, since they have to be x64?
- viraptor 14y agoAt the same time you're executing fewer instructions, because 64b instruction set is a bit more powerful. There's a balance between many things here.
- obtu 14y agoAMD64 would bring more cache pressure on the CPU, but also a lot more memory for caching the world, plus more registers, a better instruction set… For a game, I expect memory would make a large difference.
