Anybody hear about how Half Life 2 suppovely will only run at around 30 fps on a 5900 Ultra and will not run in DX9 mode with a 5600 and 5200 Ultra's? Something about Valve using 24bit color while the Nvidea cards will only support 16 or 32. I guess valve said there visually isn't a difference between 24 and 32. They've got another 5 months to worry about it though.
