I noticed in one of the recent news items (forgot which one, so many lately) that the upcoming Catalyst was going to have someplace where you can turn on TruForm or turn it off. I don't know if they were referring to just the upcoming cards or any TruForm capable card. What I'm wondering is does this mean we'll be able to force it on with software that doesn't actually support it?

there will probably be a Truform option (or maybe even a Truform 'slider') in the display properties control panel .....
for example , just like there is a slider for anisotropic filtering , and a slider for FSAA .... there might be a slider for Truform , that acts in a similar way to the anisotropic filtering and FSAA sliders

Re: upcoming Catalyst and TruForm
Forcing TruForm in software that doesn't support it would look like crap. Sorry to say it, but it's true. The only way that I can think of for the drivers to differentiate between actor models and world geometry would be by checking if the vertex in question has a normal vector. The problem with that is that per-pixel lighting requires a normal vector as well, so any world geometry that uses per-pixel lighting would be TruFormed and look like crap.
It is far more likely that the settings will be "Disabled" and "Application Preference", with several sub-division levels available to force when TruForm is enabled by software. "Disabled" would simply mean that regardless of what the software says, TruForm will not be on. "Application Preference" would of course mean that it is up to the software whether TruForm is to be on or off. IMHO, this would be a fantastic thing for ATI to do. Certain games, such as "Neverwinter Nights" and "Myth 3" allow one to enable TruForm, but do not have any way of letting one change the sub-division level to tweak performance and image quality.

Re: Re: upcoming Catalyst and TruForm
I thought that it was as you say. That it requires developer support for it to work properly. But if the software has an option for it, I just don't really see the point of having the option in the control panel as well. Unless it's to turn on some ridiculously high tesselation level that only the 9700 and future cards could do well. I mean if NWN and Myth 3 don't have a way to adjust it, I'd consider it an oversight by those developers rather than ATI. Not having a way to adjust the level of ansiotropic filtering from within a game it one thing. The developer has to worry about how that will work on other cards. It's not like they have to worry about that with TruForm.
