[B]Do all the retroarch emulator cores in 64-bit Lakka completely utilize 64-bit CPUs? Or do some of them only run in 32-bit mode even with a 64-bit CPU? I’m just wondering how much of a performance gain does 32-bit to 64-bit make in retroarch.
Would the Dell Optiplex 380 that has a Core 2 Duo E7500 2.93 GHz, 2 GB DDR3 RAM and HD4350 be a good PC for 64-bit Lakka? I’m currently using a Dell Dimension 4600C with the 32-bit Pentium 4 HT 3.2GHz, 2GB DDR, and an ATi X1050.[/B]
The Optiplex would be better, yes. Not necessarily because of 64-bit instruction set but that alone probably gives a few additional fps in certain cores. I know (at least at one time) bsnes was 5-10% faster on 64-bit.
Oh right I forgot about bsnes. I’ve never actually used that emulator before, I guess I can try it out on the Optiplex. I didn’t even bother to try it on the Dimension since the hardware is so old, a lot of the cores run great at 480p on it though.
You should be able to get 60 fps even with the Dimension using bsnes-balanced, I think.
