| DirectX VRAM-VRAM accelerated stretch blit |

Ok, proposed patch attached. It's basically the same one as the previous one except that the accelerated function is never called if the destination surface is a memory bitmap. Quote:
A little bit here, a little bit there I highly doubt it; moreso because the likely case is that the function does work properly. But if you can show some benchmarks that clearly show an improvement, then by all means share them! |

sorry to appear like a complete moron, but i got somewhat lost in all the above banter, it all sounds good thou! can you tell me: Does this patch do Vram->Vram accelerated bliting? as far as i can decipher, some problem occured that has left it in a "depends on your grafix card" answer... which (vram-> sys-> mem->) acceleration is working, and which ones are "depends on your gfx card" ? ___________________________ |

No, that's been in there since... forever. Quote: which (vram-> sys-> mem->) acceleration is working All of them, in principle. Some cards may have issues with {sys,vram}<->{sys,vram} blitting, but that's something someone else will need to look into to work around or fix. |

sorry; thats what i meant; accelerated vram-vram strech blit... that is fantastic news, well done everyone. ___________________________ |

It's done accelerated vram-vram for a while AJ, just there kept popping up new errors as I've been testing. This last fix, was to stop it from crashing when you mix memory and system/video bitmaps. Thanks, Evert, I'll try the code tonight, I've been busy decorating to try much the last few days. Once it's all working I was planning on doing some benchmarks on the various bitmap types (memory, system, video) and see how they cope under light and heavy stressing and how they work using different combinations (e.g. vram->memory, system->bitmap, etc).

Neil, not sure if you've been following my other thread I'd be very interested in seeing your benchmark results. ___________________________ |

That code change works, Evert, check the code in there are zero bugs for all permutations The only thing that doesn't work is the odd halo effect on vram-vram stretching. Thomas seems to think it is a bug. However, a bug is a bug is a thing that won't work for people. What to do? Anyway, attached is a windows alleg42.dll (and updated gfx.h) if anyone wants to use the new accelerated stretching and correct destruction of system sub-bitmaps.

Neil, is this vram->vram stretching halo thing look bad ? ___________________________ |

Yes. Do you want me to attach an example program showing it? It could be a good test to see if it is on some machines only. Either way, it sort of defeats the object of accelerated stretching when you can't stretch vram-vram! Neil. wii:0356-1384-6687-2022, kart:3308-4806-6002. XBOX:chucklepie |

Attached is almost everything you need and it will start by default with video buffer (paging) and store the bitmaps to show as video. On running you should see the larger three ufo's and they should have a magenta edge to them. The full magenta one is fine as that is a stretch_blit. The little sprites to the right should be fine as they aren't stretched. The top line should also state that it is in paging mode. If it doesn't and says double buffer, it means creating screen video bitmaps failed. Also, if you do not get the effect, press ESCape and open up the produced 'animation.log' file. You should see an entry that says how the graphics were created, i.e. normal: Animation Frame Constructor: sheet.bmp Now, to see it working properly, edit the config.xml file and change the entry: graphicsmode="2" to graphicsmode="0". This will change the buffer from video paging to memory double buffering. If you want to see how other permutations work you can change this to 1 for system double buffering, 3 for triple buffering (though you will have to change the 'autodetect' to 'fullscreen'), and you can edit the animations.xml file to change teh actual bitmaps, i.e. find the global/bmp_type and change it from 3 to another value. 1 is memory, 2 is system, 3 is video.

It seems then that the 'this feature is card specific and may or may not work as expected' property of the stretch function is active, i.e. it may or may not work on all computers. Maybe more people testing would help? Either way, do we (i.e. the Allegro coders) need to address this? maybe a flag in the stretch function to say whether to use accelerated stretching? This fault was found by Thomas Harte in a DX forum so I can't be alone. I can't seem to find any old DX reference guides to look for any disable anti-alias type flags. I've got a GeForce 5200. As an aside, this line seems odd though (its a call to get refresh rate): system returned the refresh rate as 59 I thought all monitors/displays would return the usual 60, 70, 72, 75, 85, etc. Neil. wii:0356-1384-6687-2022, kart:3308-4806-6002.

I got a laptop. It's the refresh of the LCD screen, i can force it to 60 if you want. I got a GeForce FX 5700 go. (maybe it can help to know where is the problem) Can it be a driver issue ? Have you test rolling back your drivers ? "Code is like shit - it only smells if it is not yours" |

You mean, DX may or may not support it properly despite claiming that it does? Quote: Maybe more people testing would help? Maybe. Quote: Either way, do we (i.e. the Allegro coders) need to address this? I say we (as in the developers) should do `something' with this. Either we need a reliable way to detect if the bug will show up or not, or we need a way to work around it. There might be some settings you can pass to DX (having to do with things like anti-aliasing or smoothing) to make it behave sanely. That, however, is something that someone who is using Windows will need to investigate and look into (as in, I'm not going to do it any time soon). Quote: maybe a flag in the stretch function to say whether to use accelerated stretching? Right now, I think the code is such that you actually can disable it by masking it from gfx_capabilities. This is a hack though and if it works at all it's more by accident than a feature. There is no way in Allegro for the user to specify that he wants to use acceleration for some functions but not for others. Quote: I've got a GeForce 5200. Windows and DX versions are probably relevant too. |

OK so, It is working under my WindowsXpPro SP2,DirectX 9.0C Grafic Card: GeForce Fx 5700 GO with 6.14.10.6212 drivers from nvidia. "Code is like shit - it only smells if it is not yours" |

I've got dual boot XP, one with SP1 and one with SP2, one with DX8 and one with DX9 and they both fail. Sadly I can't try a different GeForce driver as I'm limited to what Toshiba supply. It would be nice, however, if Allegro let you choose displays (will this ever be a feature?) as I have two outputs but allegro always forces itself to the primary display, I could then try it with a different video driver as each display has it's own driver installed (though fair enough the same card). Quote: I got a laptop. It's the refresh of the LCD screen, i can force it to 60 if you want. Nah, it got nothing to do with the test, it just seemed odd that your laptop is saying 59 and not 60.

hmmm perhaps more a driver issue than a specific card or other. "Code is like shit - it only smells if it is not yours" |

Firstly, someone tried it and it failed (hurrah, I'm not alone!). It was a NVIDIA Quatro NVS. I changed the Windows display property/'Troubleshoot' option to disable all DirectDraw accelerations and it worked fine. It still created and used video bitmaps though. Sounds like a bug in something or other to me Anyway, It is a GeForce FX go5200 (i.e. the mobile version of 5200 series). The problem is I've tried downloading the latest from nvidia but it crashes my computer so I don't know whether it is a modified driver for the Toshiba M2 I've got or they've kept using an older driver because of bugs. Anyway the version I use is: http://support.toshiba-tro.de/tools/Tecra/tm2/display-tm2-4644.zip According to the property page, it is version 6.14 of the driver.

i just tested in on a Nvidia Geforce4 MX 440 AGPx8 desktop. AMD64 i also then tried it on my laptop: and it looks fine, no halo, no purple crap anyway; looks good ! also tested an Geforce2 MX 100/200 and it was fine. ___________________________ |

I think this effect is visible in OpenGL with alpha channel rotated quads (at least it's visible in OpenLayer). I think Flad is going to add a function to preprocess the image to expand the edges so the edge blends to the normal colour rather than purple. Would it not be possible to use something like this as a fallback option? |

I guess if you call the function 60 times a second for each of 300 sprites on your screen, those 10 lines of additions might add up to a tiny saving?
