Ubuntu 32 ou 64 pour SDLMame?Ca depend a quoi vous jouer!

Salut

Si comme moi vous aimer encore bien jouer aux jeux d arcades, et particulierement les plus recents,
vous vous demandez surement si vous devriez installer plutot une version 64 bits au lieu d une version 32 bits de ubuntu.Depuis un moment, MAME existe en version 64 bits et cela apporte son gain de performance au jeux 3D emules.Mais, dans certain cas, vous perdrez enormement de performance sur certains type de jeux ils disaient.
et cela c est avere vrai, avec Killer Instinct, je suis tomber a 12 FPS sur ubuntu 64 alors que sur la version 32 bits toujours a 60 FPS..
l explication par Aaron Giles, un des membres les plus important de la MAME team:

finally, the 64-bit question: yes, absolutely, with the MSVC toolset, the 64-bit builds were consistently faster — and in a few cases significantly faster — than the 32-bit builds. There were a few black eyes for the 64-bit builds, but they are all cases where the lack of a MIPS recompiler for 64-bit put the games at a significant disadvantage. Killer Instinct in particular utterly crawls without the recompiler (they use a lot of lwl/lwr/swl/swr instructions which are worst case for the memory system). The Seattle and Vegas games, on the other hand, were slower, but not nearly as slow as I would have expected. Even with a super simple 64-bit drc, they should smoke the 32-bit versions. You’ll also note that Raiden Fighters Jet crashes on the 64-bit builds — guess we’re not fully 64-bit clean yet!

One thing that seems pretty consistent is that the 64-bit builds do really well on games that do 3D rendering. I can only attribute this to having more registers to play with in the innermost rasterization loops. Ridge Racer was an impressive 50% faster in the 64-bit build. Radikal Bikers was 30% faster.
