It was to program the textures to steadily stream through the buffer.

The best method took a few years to develop.

Another solution was to limit the polygon count in order to have complex textures over every object, for example GoldenEye - the textures are over almost every object, but the draw distance suffers and characters look goofy up close.

This does lose some detail up close, but it allows complex animations without having to go through the texture buffer. Link in The Legend of Zelda Ocarina of Time is a good example - aside from possibly his face, he's not detailed by textures at all. Anything more complex, like the player character, was instead detailed by gouraud shading, which is basically filling in a single color over one or more polygons.

Nintendo's method was to use textures only for objects that were the least animated, which included backgrounds.

Combined with the slow latency of the RAM, and this would slow the system to molasses of there wasn't some sort of compromise. Not only did that mean no single texture could be larger than that, if they were all that large, they would have to go through one at a time.

Just as bad, the system can hold as many textures as it needs in the RAM, but the buffer for textures to pass though during rendering is just 4 KB.Not that the bus went through the GPU, as a lot of systems do that, but those systems use dynamic memory access to allow smooth access through processors, and the N64 doesn't allow the CPU to do that. The CPU also doesn't have direct access to the memory.Ironically, RDRAM is great for playing FMV, and the one game that used those (a port of Resident Evil 2) showed them pretty well despite the heavy compression.It has a high clock speed and well over twice the bandwidth of the PlayStation memory, but the latency is so slow those advantages are negated. Unfortunately, Nintendo chose Rambus DRAM for the system. The system can use any amount it wants for main, video, and audio. There are 4 MB of RAM, which is "unified".Just about everything about the system's memory tends to have some limitation on performance, called a "Bottleneck". Memory is where the N64 runs into trouble.The GPU can also process sound, but it took away processing power for other stuff like lighting effects, or system bottlenecks kept getting in the way.Some had to make their own, and they often made superior codes than Nintendo's anyway. These offered even more system control than vector units today, but (perhaps) fears of abuse kept Nintendo from directly sharing their codes with developers.It has a Vector Unit built into, to handle special programming, called "Microcodes".Besides, like most systems so far, the graphics are mainly handled by the GPU, called the "Reality Co-Processor".So, in other words, the "64" in the name was mostly for marketing, even if the processor actually was technically capable of running 64-bit code. This was mainly used by the games because A) the bus is only 32 bits, B) the 64-bit mode uses twice as much memory and bandwidth, and C) until high definition graphics, anything more than 32 bits was actually redundant for 3D graphics. The CPU, a MIPS R4300i (the 64-bit version of the R3000 in the PlayStation) runs at 93.75 MHz and has an internal 64-bit word size, but it also has a 32-bit mode.The company's fear hurt everyone else: not only did multi-platform developers have to chop out features and add fogging so a game would fit on an N64 cartridge (as well as map controls to the system's unique controller), but the consumer typically paid at least $10 more than Saturn, Playstation, and Dreamcast titles. Nintendo's adherence to bulky, expensive cartridges instead of the far-cheaper-to-produce CD-ROM format appears to have been in part to be a fear of piracy (Nintendo's early experiment with floppy disks, the Famicom Disk System, resulted in rampant piracy). The N64 also began Nintendo's focus on local multiplayer party games. Nintendo never recovered from the lack of third-party support, and it relied on Rare to help define the system.

One of these franchises was Final Fantasy, as Squaresoft (now Square Enix) took Final Fantasy VII to the PlayStation-which offered more storage space and less censorship for games-and watched it become the system's Killer App. The N64 was a big hit in its early life, but it lost many key franchises because of Nintendo's reluctance to use CDs after the fiasco with Sony and Phillips on the CD add-on for the SNES (as well as Nintendo's general ham-handedness regarding third parties during the SNES period). Nintendo didn't drag their feet with the system this time, and released the Nintendo 64 to compete with the struggling Sega Saturn and the newbie PlayStation.
