Is Truform used much in games, or does it work independantly of any game coding?

Best setting, on or off?

Thanks in advance.
 
The only game I know that uses it so far is Rainbow Six 3. It can kill your frame rates pretty goo, I usually leave it on Application Preference and in some cases, off.
 
Not too many games use it. There is a version of half-life and counterstrike out that use it. Serious Sam 1 & 2, morrowind and UT2003 and I think UT2004 use it as well. Truform was a hardware function in the radeon 8500 series that was taken out for the radeon 9500's and above. The best is to leave it at application preference. If you set it to on it can have some very strange effect, rounding objects that shouldn't be rounded. I personally love it on my 8500 but if you have a 9500 or above it is not worth the hit in framerates you will take since is it emulated in software.

the radeon 9x00 series cards use it. and it works in most if not all Q3 based games.

It was actually introduced with the 8500.
 
It was a detractor for my 8500. I never used it and it only killed the framerates in counter-strike. I'm not going to use it in any games. It's a good theory but one that really doesn't have any backing from the industry. Correct me if I'm wrong..

yes, i know, i had one :)

and if you look closely, i never mentioned where the technology was introduced, just on of the series of cards that use it ;)
 
Truform with the radeon 9600 and up was updated to version 2.0. It wasnt removed. (not sure if version 2 is on the 9200, but i dont think it is)

Version 2.0 means software emulated. It was removed from the die. That is why the framerate hit is so large on 9500 and up series of cards.
 
UT2k4 uses it and it makes things look awesome.
You enable truform in your display properties, then you open the UT2k4 console and type 'preferences'
In the Rendering section, click on Direct 3d, then on "Use NPatching" set it to 'true' and on 'TessolationPower' *something like that * set it to 2.00

Now, truform is enabled in UT2k4. I don't have any place to upload pics, but it rounds out all the sharp edges so the guns look more realistic, the vehicles look really cool, and the character modles look awesome.
Performance hit isn't that much, most of the time you won't notice any change. The only time I had some problem was when I increased the character detail too high, and since I use a robot skin I usually break into lots of pieces so I notice a 15% drop. You can avoid this by turning down the gore level. During normal gameplay, the FPS loss is like 2%.
 
I believe you have to have Truform to get dirty uniforms in Madden 2004.

Very noticable to me.
 
The only difference I noticed was that the wrists were larger... But I wont suffer a performance hit just for wider wrists...
 
Take some screens of the Robot characters. The spikey female and the hulking non-cyclops male are good examples.
 
It's the joints. Notice where the joints are.

On the non-Truform shots, the wrists, elbows, shoulders, etc are pointy. Unrealistic, obviously-CGI, pointy.

WITH Truform, they are rounded off and look more 'real'.

Morrowind is another good example of Trufom:

Notice the difference in the boulders. Without, they look blocky and fake. With, they look...well, rounded. Like boulders should!

Here, notice the trees. Notice ESPECIALLY the two trees on the right. Without Truform, they are very definately polygonal trees. Yum, right? Well, WITH Truform, the trees get all curvey and start looking like trees.

So, yeah, it's a cool feature.

Too bad it's only done in software on the 9500+ series cards. Guess ATI felt more die should be used to compete with nVidia on their turf (FPS) rather than on adding innovative features.

Feh, maybe we'll see something like it again someday.
 
Yeah, its a shame it didn't really catch on...

Take a look at these taken with a Radeon 8500 (no AA, for clarity) Look at the places where things are supposed to be round, like the head.

what are the console commands for ut2k4 truform and how well does a radeon 9000 handle it :) ? (former is more important than the latter because I can find the latter out on my own ^^)
 
how can you not notice the difference
look at the bubble things on their hands, look at the structure of the arm it looks alot more natural on the trueform pics it prett much removes any corners on edges that should be round
