Not if you look around. There are plenty of games that even updated their game clients to have a pseudo 64bit exe(like WoW). Some games have the 32bit client selected by default, and you have to go thru some advanced menu options, or even directly into the config files to force the 64bit game launcher/client. Games that come from other countries(like Korean MMOs) have been using 64bit exes for at least 5 years, and they definitely improve performance by leaps and bounds. The difference is that games from current US devs are not ground up 64bit game code, but are instead 64bit game launchers with the same 32bit textures and everything else ported over that they could. If you look at games like Aion(yea, its a bit older, but a good example), they have had a 64bit game client since the game came out, and its a true, ground up 64bit game client, meaning it does not share hardly anything with the 32bit version, and its performance over the 32bit version is tons better. The major issue with 32bit exes is that they are fully limited to 2048MB of system RAM, and even if they Large Address Aware flag is flipped, some games are tuned and hard coded to not go over about 2000MB of RAM regardless so that they don't crash. Minus out of that 2000MB the RAM needed to crosstalk textures with the GPU(so, however much your GPU is using, the rest of the game cannot use, since its counted as a single unit in 32bit programs, meaning that if your Vram is at 700MB, the games actual usage of system RAM will be limited to 1300MB), and 32bit exes are a huge reason performance gets hit so bad, and games need a lot of "optimization" so they can run within the tight confines of the borders that have been set for them by windows ages ago. Back when I used to play AION regularly, and even now, when I fired it up, with the 64bit game client running, the RAM went up to 3.5GB of usage from just the game, and load times and texture load lag is nowhere to be found, with 40+FPS everywhere, but on the 32bit client, im limited to about 1.2GB of system RAM(780MB Vram), and the game loading screens take a long ass time. The move to 64bit OSs for consumers happened with vista, and then 7, and game developers are stuck on consoles, which are essentially 32bit. For games to improve anymore than they have already, they need to move to 64bit so they can take advantage of all the additional system resources that 32bit programs are not allowed to access. SSDs are a sidestep for performance increasing when the actual programs themselves are the limiting factor now. If more companies used 64bit programs, they could load more up in RAM(~8000MB/s read/write speeds), and read the HDD/SSD less. SSDs and HDDs become irrelevant in program performance once you can load a majority of the game into the much faster system RAM and not have to read the storage as much. BTW: this game does not like running with the LAA flag enabled, since it crashes out at 1.8GB system RAM(and 600MB Vram). It also does not SLI with twin GTX 460 1GB cards either. My PC runs BF3, BF4, and everything else I can toss at it awesomely, but this game still runs like crap. I just hope it does not turn out to be another minecraft, where they stop improving performance because they chose a ****ty start for the game code. If they have to jump ship from unity to get better performance, I really hope they do. Think how well Minecraft would do performance wise if they switched to C, or C#?
