 Notice. New forum software under development. It's going to miss a few functions and look a bit ugly for a while, but I'm working on it full time now as the old forum was too unstable. Couple days, all good. If you notice any issues, please contact me. |

Will it run on Linux? |

As per the title, Peter is coding for Windows. I assume that it might run under Wine etc. Provided all the strange extensions being requested are left out and the code kept relatively 'normal', there is a chance the it may be possible to compile it for other platforms.

What did you do ? The current 5.05.01 DOS version runs 123570 grains on a i9 (absolutely not the slowest machine). 3x more performance. WAUW... Volhout PicomiteVGA PETSCII ROBOTS |

What is the screen resolution? User configurable? |

Heck....Game changer for me....possibly. |

Will be - just got that working without even needing to restart Can't decide whether to mimic CMM2 resolutions up to and including 1080p or to give complete flexibility. In all cases colour depth will be ARGB8888 and I think I'll set it up with two pages and transparency so you can do things like have a graph moving over a fixed grid. |

I wonder about the overhead of doing graphics at high resolution, especially with sprites. Also, since the interpreter is doing font stuff in software will there be a bottleneck somewhere? Maybe this will not be an issue since running on a PC looks much faster than any other MMBasic platform. (after 2 minute read of olcPixelGameEngine wiki: interesting, "decals" are GPU accelerated sprites but with some restrictions - see https://github.com/OneLoneCoder/olcPixelGameEngine/wiki/TUTORIAL---Decals ) (after 5 minutes thinking): what about using decals as the font char primitives ("A", "B", "C" etc) to draw text to screen? If I understand it correctly decals have highest priority over the background (i.e. stuff drawn by CPU) so you can't use sprites etc on top of decals, but would be fast though.

Coming together nicely  Graphics demo Mode change is also now implemented, all CMM2 modes + completely free resolution MODE n ' select a CMM2 mode but in full ARGB888 mode width%, height%, pixelsize% 'specify the width and height and the size of a MMBasic pixel in screen pixels The latter syntax allows you to have a huge window but with say 320x240 resolution from MMbasic's perspective |

Does it make sense to have an additional high precision timer other than the 1 mS base timer? Since PC is fast, using 1mS base timer to try to measure code execution time might not give the precision required (i.e. a lot of code could probably execute in 1mS?). On the other hand, if the speed is so fast maybe you wouldn't need to measure/optimize code execution a lot... |

Not bad at all, Peter. Do you think it might need speeding up a bit? ;) Mick Zilog Inside! nascom.info for Nascom & Gemini Preliminary MMBasic docs & my PCB designs |

Yes, I haven't start tuning it yet |

Only waiting for this to be ready to port the Into The Darkness to a full 60 FPS raycast engine... Unfortunately, the CMM2 struggles to keep 15 FPS in this game thanks to my lack of ability to optimize it more. |

Impressive demo.... I understand the choice for the mode command, but I hope there are additional options in the future. Most screens on PC's are 1920x1080 nowadays (16:9) and the CMM2 modes do not scale nicely on that resolution. 1024x768: no scaling, uses approc 1/3 of the screen 800x600: when scaling 2x, exceeds screen dimensions: no scaling possible 1/4'th of screen 640x480: scaling 2x => 1280x960, uses around 2/3 screen, that is not to bad scaling 3x => exceeds vertical size. I hope some better matching video mode van be found. Otherwise 640x480 gives best result. Volhout PicomiteVGA PETSCII ROBOTS |

Mode 16? |

| Volhout Guru Joined: 05/03/2018 Location: NetherlandsPosts: 3507 |
Yip Mode 16 was not available on my Gen-1. But Mode 12 with double pixels is just as fine. Matches exactly. Might have been designed for that ..;) Volhout PicomiteVGA PETSCII ROBOTS |
