I have an MGA 2+ with 4 Mb ram in a Micron Pentium/66. I use the following resolutions and refresh rates in Windoz on a ViewSonic 21: 1024 X 768 24bit 100Hz 1152 X 882 24bit 76Hz 1280 X 1024 24bit 90Hz The display looks as solid as a rock at these refresh rates. My problem is when I run 3DS3 the refresh seem to be below 72Hz (flickering). I am using the Inline Vibrant drivers, but I haven't found a way to specify the refresh rate at a specific resolution. It seem like the Vibrant drivers are ignoring the MGA.MON file the refresh rates are specified. I am running the Main display at 1280 X 1024 8bit and seems to be running at 60Hz-66Hz(flickering). I run the Material and Flic resolutions at 1024 X 768 24bit and they also flicker. The card is really fast, but what can I do to increase the refresh rates? I can always use the Matrox supplied display drivers, but this will rule out the purchase of Liquid Speed.

Yep, I got the same situation here. In fact, I run my editor at 800×600, and sometimes the monitor starts -SCREAMING- from the inside… very frustrating, I can tell the specs aren't correct for the Mag 17F… Unless Vibrant works hand-in-hand with Matrox (which, ask Pavel, can be really really difficult) you won't see your max. refresh under 3DS… sorry!

You can see max. refresh rate with Impression PRO. I wrote the small IPAS which can set maximum refresh rate. I'm running 3D Editor in resolution 1280x1024x24/76 Hz. PavelK

Is said refresh routine MGA-I specific?

Thomas, I don't know. I tested my refresh correction IPAS on my Impression PRO only. But I'm affraid that this routine is not possible to use with MGA-II. But I'll upload this small IPAS here on CIS and we will see. PavelK

Scott, are you sure about the 1280x1024x24bits thing? Did I miss some secret updates for my Ultima? 🙂 ana /krazy images
