As the newer internal Mame drivers start to appear in the next year or so, graphics card performance WILL start to make a difference to Mame performance. --- End quote --- That would certainly be nice if true. Just curious, where'd you read that? I've always heard the mamedevs say that due to the non-uniform nature of graphics hardware and APIs, they render everything in software (CPU) and then just use the GPU to copy the single rendered 'polygon' to the screen. --- End quote --- The card can make a difference, but not because mame will let it emulate the game's rendering. (ahofle, you're right about how mame does the video.) Mame now uses direct3D by default, & some directX 9.0 stuff to display overlays & bezels. Mame still emulates the graphic calulations in the CPU, but can offload the final rendering to the card (mostly the overlay & stretch to screen). Basically, a card that does directX 9.0 in hardware, has nice d3d, and (optional) clean s-video out is all you need. However, a semi-new card that does directX 9.0 in software, or older that can't do dx9 or dx8, or does d3d in software, or an onboard chip that shares main memory, can be noticeably slower than a good card. |

I was a little hazy on some of it. Best Regards, Julian (Fozzy The Bear) |

I know this is a bit of an overkill but it was free so i'll take it! --- End quote --- I still cant run some chd's and some roms at a decent speed and i got Athlon 64 3800 box 2.4GHz AM2 Asus M2N-E Socket AM22000FSB SATA ATX Corsair 1GB (2 x 512MB) Asus Nvidia 7300GS 256MB PCI-E I toyed for ages if to get a spec this high but im glad i did the emu comunity will grow and it STILL amazes me how kwik hardware becomes out of date also its a pleasure to work on a decent pc when u are doing a lot of trial and error stuff with front end etc and as im using gameex (which i didnt know when i bought the hardware) its an added bonus to have a decent pc.. ive got a few 1ghz sys lying about and if i do another cab im going top see how low cost i can do it |

Out of curiosity.... What if I just used a vga to s-video adaptor for now until i invest in a nicer card? Will that work? Not sure what the specs are of the generic card. Thanks all! |
