The sky looks blocky and textures have strange colours in Quake 3 Arena with the latest drivers installed. How can I fix this?
This is a by-product of the S3TC support in the latest drivers. Basically the S3TC format used by default in Quake 3 Arena (DXTC1) forces textures to be in 16-bit colour instead of 32-bit. • The following registry key was found by Unwinder: In the 6.47+ drivers, you can use the s3tcqualityon.reg registry file to force all OpenGL applications to use DXTC3 compression instead of DXTC1 – available here: http://www.geforcefaq.com/files/s3tcqualityon.reg If you get problems, you can reenable DXTC1 compression using the s3tcqualityoff.reg registry file – available here: http://www.geforcefaq.com/files/s3tcqualityoff.reg If these files don’t seem to have any effect, you may have to edit them in Notepad and change the 0000 to 0001, or another value. Take a look at the HKEY_LOCAL_MACHINE\System\CurrentControlSet\Services\Class\Display registry key using regedit and find out which number your graphics card is using.
