I tried launch my port on Gigabyte U60:

CPU: VIA C7-M 1,2Ghz

RAM: 768MB DDR2-533

Video: S3G UniChrome Pro II IGP (64MB)

There is framerate between 30-80fps (120fps max). 30fps when ROR is drawing. Btw, such framerate has eduke32. So, Java and C++ have same performance in case with my port :) Preview picture has a link.

Also I would test my port on Sony Vaio PCG-C1VPK (CPU TM5600 and Video ATI Rage Mobility-M1 (8MB)) but today I noticed dead backlight on screen :( It's need to repair it now
