ICR2demo and ATI GFX Xpression

The univbe driver that comes with the ICR2demo doesn't seem to support my mach64 card (ATI Graphics Xpression). When I install it, the display flickers and I get 2-3 fps instead of the 10 fps i get without it. Has anybody else tried to install univbe with this card? Would it increase the frame rate if it worked? Sven Dahlin [link lost in import: /~f89-sda]

I had the same problem. It be easily fixed by running UVCONFIG.EXE in the ICR2 directory. Check the option for the linear frame buffer (the third one I think) and it should work fine. -- Thomas O'Donohoe http://www.lookup.com/Homepages/60188/home.html

Same here, doesn't work with my ATI mach64 WinTurbo. But it would be nice if they came up with something to give me a few more frames per second. I fiddle with the details until I can usually achieve 14 frames per second as a bare minimum (18 would be nice and 20 would make me happy, but 30 would put me in ecstasy!). -- **************************** Michael E.

Read elsewhere in this group to try turning off the Linear Framebuffer. I did this and it now works with my ATI WinTurbo card. However, I didn't really see any improvement on frame rate. Maybe this is where the increase comes from (enabling the Linear Framebuffer). Oh well... -- **************************** Michael E.

You bet. A linear frame buffer is the same as flat memory, ie memory mapped in one segment(one heap) as opposed to segmented memory where you have, on the Intel architecture, 64K segments. Having all the memory in one pool speeds applications up considerably since a lot less overhead is needed to manage memory buffers, dynamic allocation, etc. Linear frame buffer can only be utilized when in protected mode. ICR I, ICR II, NASCAR, Doom, etc, uses protected mode. The DOS4/GW banner you see when you start the games means that the program was compiled with the Watcom C / C++ compiler and that it uses DOS4/GW protected mode run time system. -- Terje Wold Johansen "I am your inferior superior."
