If you will find where was the problem, please come here and say. Rebel must have around 240000 nodes/second average on AMD 600Mhz. Your problem could be trick of Windows 98 when it run on AMD. Have seen the same problem when changed Windows 95 for Windows 98 on AMD 400Mhz. Found this not with Rebel but with my game written for DOS. Game sporadically slow down as much as 15 times. Occur when game used DOS after leaving Windows 98. From Windows 98 game run all the time at normal speed. Leonid.
