There's
no performance gains with the x64 version over the x32 version.The only advantage to using the
64bit version is
more bugs and lack of "Enhanced" blitter.Also, never trust outside exe's unless you absolutely trust the source/person compiling it. I know, it's common sense these days, but, I have to mention it just in-case
how to test 32bit version vs. 64bit version:
The NES emulator in fbneo is pixel-accurate, so its a slightly heavy on cpu - and makes a good testcase. load up castlevania iii - dracula's curse
press backspace once to show FPS
hold F1 (FFWD) for about 10 seconds and note the maximal fps value you get.
now do the same with the 32bit version.
I get 90fps on the 32bit version and 89 on the 64bit version on my I7. Since the FPS is always changing and a bit chaotic, I'd say they're about equal.
Also please don't apply this logic to other apps/games. For example, many newer (mostly 3d) heavyweight games and apps do run better at 64bit.
Also note, of course we can get better FFWD FPS by tweaking settings, but the idea here is to get a baseline reading for both versions using the same & default settings.
