> did some tests with Quake 3. Graphics is faster in some resolutions upto 30%

That's way below expectations I'd say.

"Then we were shown the updated 3D drivers, reaching 140fps in Quake III running at 800x600 on an humble Mac mini. That's roughly 50% better than last year, that in turn was already 100% faster than what we have in the public version of MorphOS..."

That would amount to an improvement by 200%, instead you report 30%. Underwhelming to say the least.
