DirectX 10 Backwards Compatibility
Copyright Feb 28, 2006
Disclaimer: I'm speculating in this article, and by the end of 2006
this article will probably be nothing more than a stupid rant.
Via Slashdot I came accross this article which mentions the new version of DirectX, version 10. DirectX 10 sounds really nice, except for one major thing.
"DX10 will use much faster dynamic link libraries (DLLs), and won't incorporate older versions of DirectX, as is done today."
This really sucks. The article goes on to say that Vista will
support a side by side install of DirectX 9, but still, they're
abondoning lots of backwards compatibility.
The major problem that I see happening is when upgrading to a new
DirectX 10 compatible card (read the article for more on that), and
upgrading to a CPU/Motherboard combination with digitial rights
management, and the mandatory new Monitor with digital rights
management, will I be able to play my favorite OLD games? A
DirectX 10 video card, with a totaly new driver model, may not
necessarily support legacy COM interfaces.
If I can't play my favorite DirectX 5 game, which happens to be Starcraft, then that sucks.
The updated driver model for DirectX 10 is a great idea, but this is
going to double the work of video card companies because they're now
going to have to develop a DirectX 10 driver and a legacy driver for
DirectX 3-9. Emulation is obviously not possible since
DirectX 10 does not support the legacy interfaces.
