>The current drivers for 3D Studio 3.0 are VESA drivers, they are >not mach64 specific and do not make use of the accelerated >features of this card. ATI does not write these drivers. I am unsure what exactly this is refering to… The Vibrant Inline Driver version 1.0.3 does include native Mach64 draw-code. 1.0.4 adds native ISA support. VESA is not used for these modes and the initialization is peformed by the ATI BIOS. >The delay you are experiencing is due to the way the VESA modes >are implemented on the mach64 card. The delay occurs because the >mach64 initializes and verifies ALL available features, all >available colour depths, resolutions and fallback refresh rates >that are configured. >We are investigating ways to reduce this initialization time. We too are looking for a solution to this problem in the Inline driver. Tim Little is continuing his research into the causes of these delays and any possible work-arounds.
