radeon and s3 texture compression

[jad]

does the radeon support s3tc in hardware, software, or at all ?

 

[rickn]

yes, it supports it. DXTC and S3TC in OpenGL. Decompression is a hardware feature

jad, I hate to break it to you since you are having a hard time with your Radeon, but there is an issue with the LOKI OpenGL and Radeon cards. When you launch the game in OpenGL it will crash. The only way I know of to get around this is to first start the game in D3D, then switch to OpenGL. Once it is running it runs just fine. I don't know of any work around for this. I have been meaning to send an email to Epic and see if they know of this and if there is a plan to fix it.

oh man, way to burst my bubble and another reason to hate ATI

 

[oldfart]

I sent an email to Epic about this. Don't know if it will help, but if I get any info from them, I'll let you know.

hey thanks i appreciate it, and thanks for downloading those other game demos i was having problems with to see if u would have the same problems, someone mentioned it might be dx 8a, are u using that version ? or a prev version of directx, and also what radeon driver are u using ?

Win98 SE, DX8 (not 8a I don't think), 7089 drivers.
