I find the lack of support for anti-aliasing in many PC games, specifically multi-format games, somewhat depressing. DirectX 10-compatible cards have been around for, what, four years now yet developers still stick to the dated DirectX 9, which has serious limitations with AA when the engines use deferred rendering. I've actually played some console games which have AA where the PC doesn't and that just stings, e.g. Sonic & SEGA All-Stars Racing which is completely AA-free on the PC. I think even GTA IV on the 360 uses 2xMSAA yet the PC version has none. Considering the Xbox 360 uses DX9 with DX10-extensions it just screams laziness to me that the same isn't done on the PC. And don't even get me started on Unreal Engine 3 games, seemingly written with the consoles in mind and frequently lacking even basic graphics options never mind v-sync or AA.
Personally, I cannot wait for the next-generation of consoles so that we can finally lay DX9 to rest and move onto to DX11 (or 12). Anti-aliasing should be a prerequisite for modern games, especially on the PC, not a hidden extra that has to be forced (if it can be forced) through the graphics drivers!
