S3TC or not S3TC...

[kevinO]

that... is my question.

does the radeon support s3tc in opengl or not? i know it uses "texture compression," but nowhere can i find conclusive proof that it's s3tc that's being used, or if it's even available in the current drivers.

anyone up to tackling this one?

Here is the registry change:

[HKEY_LOCAL_MACHINE\Software\ATI Technologies\Driver\0001\OpenGL\] "OGLEnableTextureCompression" = 1

I won't be able to try that out until my card ocmes in stock. Maybe yokomo[Radeon] can try it out for us.

Addendum: I just discovered that there is a setting in the drivers for this. No registry prowess needed

So, we should be able to take advantage of the S3TC file pack on the 2nd UT Disc, am I correct?

Sorry to disapoint you Dyno, but from what i heard, the textures on the second disc only works on the S3 MeTaL API. Any chipset other than S3 will not work with that API.

 

[Dartastic]

Exactly Sasquatch. Unless ATI makes a Metal wrapper you can plan on using your second disc as a frisbee.

GL_S3_s3tc: same as in the Savages. If you want to test the S3TC in Quake3 then the Diamond Q3 S3TC levels are a good idea . Some textures are 1024x1024 i.e. 16 times bigger than usual, you should notice the difference

You'll need an Exclusive level and dmmQ3.exe (dm2 is very heavy).
