Maybe fgfs needs a certain minimum texture size that is not available with 8MB memory. You could try to reduce the resolution in order to make more texture memory available. This may also improve performance with other applications due to reduced texture swapping. > > > > Is there a savage IX chip with 16M? > > There were some, but I don't think they ever left S3's testing labs. > No commercial vendors that I know of used them. FWIW, 16MB is the theoretical limit you can get with this chip because of the layout of the PCI address mapping. > > Alex > -- | Felix Kühling <[EMAIL PROTECTED]> http://fxk.de.vu | | PGP Fingerprint: 6A3C 9566 5B30 DDED 73C3 B152 151C 5CC1 D888 E595 | ------------------------------------------------------- SF email is sponsored by - The IT Product Guide Read honest & candid reviews on hundreds of IT Products from real users.
