Public bug reported: snes9x-gtk exhibits very high cpu usage all the time on my quad-core core i5 system with a regular clock speed of 2.67 ghz. My system seems to only run at 1.2 ghz during these benchmarks regularly, but it is still very fast. I will create another bug report for the cpu frequency scaling issue.
By default it runs in software rendering mode rather than opengl mode. For these tests, I used the free homebrew game called N-Warp Daisakusen (1.1) You can find it here: http://gra.dforce3000.de/ I let it sit at the title screen during these benchmarks. When in software rendering mode and running full screen (1920x1200) or in a nearly full screen window, it uses up 100% cpu core usage (split between snes9x-gtk and Xorg processes) according to gnome-system- monitor. The game runs slowly with garbled sound. When in opengl rendering mode and running in a nearly full screen window (1920x1200,) the total CPU usage between the two processes is about 32%. When in software rendering mode and running in the default (tiny) window, the total CPU usage between the two processes is about 40%. In comparison, snes9x under windows 7 x64 has about 7% cpu usage in the default tiny window using directdraw (2d acceleration only.) I've tried deleting the config file (~/.snes9x/snes9x.xml) to make sure there are no leftover non-default settings.
