Realitygraphics system. Fortunately eBay in time had a DG5-8, GE16-4 and 2 RM10-256 boards for extremely cheap so after swapping the boards I now have an
InfiniteReality4(the last generation) only differs by offering the RM11-1024 (1gb of texture memory) versus the 256mb per board I have in the RM10s in addition to Pixel Fill Rate differences of nearly double.
jcBENCH. Surprisingly with the extra 200mhz (50% increase) and enhancements the R14000 MIPS cpu brought, my Origin 300 is over 3 times faster in both integer and floating point tests.
gmemusage). I tested it twice to make sure, but a word to the wise, do not run Quake 2 in a window if you only have 128mb of memory. I'll test it out with 192mb shortly. In case anyone was interested here is an updated list: 320x240 128mb - 180mhz R5000SC - 4.1 / 169.6 seconds 1024mb - 180mhz R5000SC - 14.9 / 46.3 seconds 1024mb - 300mhz R5200SC - 18.8 / 36.7 seconds 640x480 128mb - 180mhz R5000SC - 12.2 / 56.3 seconds 1024mb - 180mhz R5000SC - 12.4fps / 55.4 seconds 1024mb - 300mhz R5200SC - 14.5fps / 47.4 seconds 800x600 128mb - 180mhz R5000SC - 10.2 / 67.3 seconds 1024mb - 180mhz R5000SC - 10.3 / 67.2 seconds 1024mb - 300mhz R5200SC - 11.7 / 58.7 seconds
CRIMEgraphics core is tightly integrated with the CPU. Using the following commands on the console:

SDLQuakeand running into x86 assembly, UDP and linking issues I decided to try the "official" IRIX port from SGI. Oddly enough, Quake II runs at 640x480x16 with full textures on my Silicon Graphics O2. Feeling adventurous, I wanted to see if it would play with the x86 Windows 3.20 version. Sure enough, I was able to play with an IRIX hosted game (it would probably work the other way as well) with my Windows 7 workstation.

SDLQuaketo get all the way to the linking stage before giving up on it. For whatever reason using
-lSDLwas not including what looks like X11 or OpenAL libraries. I included both of those libraries and was still getting the errors.
