10.3: Possibly make older video cards functional again
Authored by: cydeout on Nov 12, '03 11:48:27AM

I've successfully used this hack to force Panther to run my SGI monitor.

NOTE: this hack does come with a steep price in performance, as it appears (I can't prove it, but this is my observation) to disable Quartz or OpenGL on ALL monitors. That, or extra CPU cycles are needed to run the non-OpenGL card.

One of the benefits that I saw on my machine before I ran this hack was a substancial increase in speed while Panther only ran my original Radeon Mac card. Quartz was used beautifully in screensavers, etc. Since I've never used that card by itself with any 10.x system, I always had a problem with Quartz running slow. I always thought it was because my G4/400 was just ancient.

However, Panther ran beautifully on that card alone, and once I used the hack, Quartz or OpenGL is gone from both monitors/cards. The screensaver example I gave above is back to its old self of not being able to render things smoothly.
