Post subject: | Is raydium need an optimization? |
I compared my 2.66 Ghz machine with PS2 who only have a 400 Mhz processor. The result is very different. Here is using raydium, my code is based on skel.c The Frame Rate is 25 FPS with CPU usage 40% Compare it with this It was at 60 FPS on 400 Mhz machine. The different is almost 2.4 times faster. Is it raydium who need optimization or me the one who got less knowledge on programming technique? Quote: The following are the basics of the PS2 specs: CPU: 128 Bit "Emotion Engine" System Clock: 300 MHz System Memory: 32 MB Direct Rambus Memory Bus Bandwidth: 3.2 GB per second Co-Processor: FPU (Floating Point Multiply Accumulator x 1, Floating Point Divider x 1) Vector Units: VU0 and VU1 (Floating Point Multiply Accumulator x 9, Floating Point Divider x 1) Floating Point Performance: 6.2 GFLOPS Compressed Image Decoder: MPEG2 Graphics Clock Frequency: 150MHz DRAM Bus bandwidth: 48 GB Per Second DRAM Bus width: 2560 bits Pixel Configuration: RGB:Alpha:Z Buffer (24:8:32) Maximum Polygon Rate: 75 Million Polygons Per Second 3D CG Geometric Transformation: 66 million Polygons Per Second Audio Number of voices: ADPCM: 48 channel on SPU2 plus definable by software Sampling Frequency: 44.1 KHz or 48 KHz (selectable) l/O CPU Core: Current PlayStation CPU Clock Frequency: 33.8 MHz or 37.5 MHz (selectable) Sub Bus: 32 Bit Interface Types: IEEE1394, Universal Serial Bus (USB) Communication: via PC-Card PCMCIA Disc Media: DVD-ROM (CD-ROM compatible) Quote: My machine

Hello, Graphic rendering is directly related to video card. What is your video card ? For information, simple application with cocorobrix.tri and camera move run at 200fps with an nvidia 8400, and even more that 100 fps on an old ati 9500. It depend on video card, resolution and some other parameters. Have a nice day. Ouille. |

Simplier. You can not compare different architectures. Try to emulate MetalGearSolid3 in a PC with a pentium 400hz and tell me the framerate |

I bought this computer 3 years ago. I dont know about cocorobrix but it doesnot displayed correctly on my machine, I only see a black object covered the sky. Can I know what is minimum requirement for raydium? |

If my computer doesnot meet the raydium minimum requirement I guess I have to wait until I can buy another computer. Raydium is easy to use, I cannot just leave it. Keep up the good work. |
