I have, like, dozen projects I passionately want to finish. Moreso now, that there's RTG running at 2,000 MIPS under Emu68k. I'm sure everyone else who has C++/3D skills is in the same boat. Besides, why would somebody want to devote a huge chunk of their life just to please 3 and half people that would actually appreciate it and not bitch about "it's not real Amiga" for next half century? That seems like quite a horrible waste of life, actually. I always felt passionately about OpenGL on RTG, but even with Vampire V4, the 160 MIPS just doesn't cut it (for texturing), so it was in the back of my queue. But 2,500+ MIPS is a whole different league which is making me repriotize working with my RTG-based flatshader (just need to replace few CGX calls with P96). |

Unfortunately, it looks like they turn off mipmapping too, so it's tiny bit grainy in the distance. But still better than blurry. Especially at 16-bit color modes, doing bilinear is just burning through the MIPS, when you have to shift in and out the bits. It's fine, why you have a silicon do the job (like it's done with 3d cards), but it's a horrible waste of performance on a CPU... |

If I had a Popcorn smiley to hand, I would have posted it ages ago with a lump on the side of the head too, but....

Wasn't aware an Amiga with a PiStorm could do that stuff! Kin stands by exit door with foot jammed against the frame...... If a CM4 module can do a tad over 2600 MIPS in SysInfo for a 2.3GHZ overclock, all I wanna know (& prolly the whole of Pi Fans on EAB) is what a CM5 (if it released) can do when it's ass is overclocked.

2 years ago, I ran my flatshader on Vampire V4 in 1920x1080. Full-screen redraw. Every single pixel. It still ran at more FPS than plenty games 30 yrs ago. Certainly would qualify as playable back then. And that's ~160 MIPS (though, admittedly, with Vampire-level RAM bandwidth). The current 2,600 MIPS is - what - about ~16x more (can't be arsed to alt-tab to calculator now) ? Certainly more than enough for a full 4k res and probably approaching 15-20 fps. Halve the number of pixels by making a racing game with half of screen taken by cockpit and you for sure have a playable 3D game on RPi at 4k. It's not a textured Quake, sure - although I would hazard a guess that a non-textured Quake at that res would still look pretty neat. |

BTW, a 15 fps lock is way smoother than occasional 30 fps but falling down to 12. It's the framedrops that kill the immersion. If you design the game around the target framerate, it can be quite smooth in what is perceived as a low number. |

There doesn't appear to be much in the way of a possible CM5 module yet?
Guessing it would need more interface pins for the carrier board. Can anyone shed any light on this? |

If the CM5 uses an onboard PCIe chip for GPIO, it can use the same pinout and connectors as the CM4 - of course the same latency problem will hold true there as for the Pi5. |
