Speed in games.
Hello.
Just a quick question that i have been pondering about some time. I played the game Elite 2 a few days ago and i noticed that it was realy slow when panning and moving around when close to a planet or when the screen had alot of objects to draw. Now to my question, does the game benefit at all from my blizzard 1230? because it feels like the game runs exactly the same on a A500 with 1mb of ram. I know that the 1230 plays alot of games @ stock speed because otherwise it would be unplayable in alot of games but i thought that games that are demanding should benefit of the extra speed.

now i'm sure someone on here far smarter than i will correct me, but i believe that most (not all Wing commander gets faster and faster and the cpu grows) games won't fun any faster than they were coded to , something to do with having to wait for the copper to fill/clear? c'mon someone help me out here!

Yes, most 3D type games that use the normal Amiga chipset (not RTG) won't speed up hugely from adding a faster processor. As JuvUK said it's because the Amiga is using the Blitter to render all the graphics and this won't speed up by changing the CPU.
They will be a bit quicker though as obviously all the vector math & game code will speed up. Just not the graphics rendering. |

If the code were to be relocated to fast ram it might be quicker. Not all Amiga Vector games used the blitter, so if they used CPU primarily for drawing the vectors, then it would speed up. Stunt Car Racer doesn't use blitter for instance.

I seem to remember Frontier running faster with my 030. Could be wrong and confusing it with WinUAE though.

I am not experienced at all in these things, but: Is it possible that the speed of some games is synchronized to "something"?
Example: The original F1GP runs at the same speed - independend from the CPU/acc. you have got. But here exists a patch that let you change the framerate. This version really "runs" on a 060 while the original version just "crawls" with the same CPU (this patch is implemented in F1GP96 for example). EDIT: Some typo..F1GP (Formula One Grand Prix)...not F1GB. Sorry. Last edited by mombasajoe; 16 January 2009 at 13:10. |

Remember running some 8bit conversion driving game on 060 which wasn't tied to the VBlank. Wow, no chance to stay on control.

Ok, thanks for clearing that up...somewhat ^^
Are there anything i could do on my end to speed the game up? the patch that was mentioned is that for the first version of the game or is there a patch for Elite 2? It's a whdload game and is there any option or flag i can set to maybe speed it up? It feels so jerky when you play it, and i remember it to be super-smooth on my pc. Thanks alot so far guys. |

A guess, I've not tried this:
If Elite 2 is tied to the blitter & therefore doesn't speed up with a faster CPU, maybe a patch such as CPU_Blit will help... ...redirects blitter calls to CPU routines... ...of course that depends on the game doing things in a 'legal' way rather than banging-the-metal... |

There is hope as Frontier doesn't kill the OS - it keeps it open so you can save/load. I'd imagine it would probably call OwnBlitter() and then bang the metal... so would need to be patched by hand.
But if it uses OS calls then your patch might do it ...assuming it uses the Blitter at all. As Galahad said some games don't. |

If you are talking about the "patch" I have mentioned: This is just an example for such a patch/enchancement (game: Formula One Grand Prix). I do not know if there is something like that existing for Elite.

I'd imagine that David Braben being just a little bit clever like, will have used the Amiga rather well - there is an enormous amount of data that clearly had an effect on the amount of times this game's visuals updated even if it is written in assembly.I think it's a little absurd to think Frontier would ever be patched, it's a bloody miracle it moves at all on an A500 considering what is being asked of it.It's easy to get this running great on Winuae of course so is it worth looking into even
Also run F1GP in NTSC on a standard A1200 setting for a much nicer movement - it is however locked regardless of how fast the cpu setting so the only thing a faster cpu does is lessen or stop the games's fps dipping under the 17 or so it was set Last edited by Adropac2; 17 January 2009 at 01:31. |
