hello hello...
1. the following was cribbed from the adoom documentation...
FPS Counter
===========
Use the -fps option to get a frames-per-second display in the upper
right hand corner of the display. This shows the speed of rendering
at that particular moment. The proper way to get the average speed
of DOOM is to do the following:
ADoomPPC -forcedemo -timedemo demo3
(or download the adoom gui front end)
2. sorry, not sure what you mean, to do what with? if you are talking about adoom, then remeber the game was built to run on a 320x240 display. 640x480 is nice enough. and run it on a voodoo screenmode as this negates the need for C2P conversion. AGA shouldn't even come into it.
if you are comparing AGA to Voodoo3, then just run the same screen mode on each and see what you get.
