100% CPU is not normal at all. Running osgviewer cow.osg on my Intel Core i7 + Radeon 4670 + Kubuntu 9.04 (KDE) with Proprietary AMD/ATI drivers I get: Tasks: 191 total, 1 running, 190 sleeping, 0 stopped, 0 zombie Cpu(s): 1.2%us, 0.3%sy, 0.0%ni, 98.4%id, 0.0%wa, 0.0%hi, 0.0%si, 0.0%st Mem: 6021404k total, 935360k used, 5086044k free, 38756k buffers Swap: 8000328k total, 0k used, 8000328k free, 353980k cached PID USER PR NI VIRT RES SHR S %CPU %MEM TIME+ COMMAND 3507 root 20 0 586m 114m 25m S 5 1.9 0:15.56 Xorg 4223 robert 20 0 254m 33m 22m S 4 0.6 0:09.40 osgviewer 3973 robert 20 0 255m 23m 17m S 1 0.4 0:04.44 kwin The desktop compositor was on so added extra work, but as you can see the CPU's are practically idle. Note this test was done with vsync enabled, with osgviewer running at a solid 60Hz.
