This post reminds me of a tech support post I saw yesterday, regarding the user cannot play a game made available in last year.

In the end, it was found that the user is using a PC bought in 2003, and the display card on it only supports DX7.

Okay, perheps that means game developers should hold all the game development targeting DX10/11 and keep writing games only for DX7 now then... Tongue Out
