Re: [PD] [Gem] performance issues on ubuntu (no hardware accel?)
hi all finally i solved the problem. gem couldn't access the direct rendering infrastructure, because in my .pdrc pdp_opengl was loaded _before_ Gem. that means, it was not a problem during compile time, but it occured when loading the externals. ___ Der frühe Vogel fängt den Wurm.

hello, in order to know if your driver suport hardware acceleration, you can try : glxinfo | grep direct if it says yes : then you have hardware acceleration, so gem should use it. anyway, ubuntu do not distribute by default binary driver, so the opengl stuff is not very efficient. i think you should install the binary driver (if compatible with your vision of open source) once this is made, you should have good acceleration, and gem should use it. well, i hope it help, cyrille Roman Haefeli a écrit : hi all i am trying to use gem, since i changed to ubuntu. i used gem before successfully on windows on the same computer. but since i started compiling gem myself on ubuntu dapper, i am not convinced by its performance and i strongly believe that i am doing something wrong, or anything on my computer is not optimized etc. specs: Pentium M 1.7GHz Ati Radeon Mobility 9600 Ubuntu Dapper Xorg 7.0.0 xorg-driver-fglrx gem from cvs (checked out today) the output of './configure': http://romanhaefeli.net/gem_configure.txt why am i thinking that gem is not working well on my computer? the screensaver also does opengl stuff, that seems to be quite complicated in my eyes and it does eat only a little of the cpu-power, when running. also running the same gem-patches on windows seems to be not only 2x-3x faster, but maybe 30-50 times. running fgl_glxgears gives me values between 440 and 450 frames per second, which makes me assume, that hardware accelerated opengl works on my computer. you should have 10 time more with this card. so i suspect gem no to use any hardware acceleration at all and i wonder why. is there a way to check, if gem uses hardware acceleration? if yes and if my gem is _not_ using hardware acceleration, what do i need to do in order to make gem use of it? many thanks in advance roman ___ Telefonate ohne weitere Kosten vom PC zum PC: http://messenger.yahoo.de ___ PD-list@iem.at mailing list UNSUBSCRIBE and account-management - http://lists.puredata.info/listinfo/pd-list ___ PD-list@iem.at mailing list UNSUBSCRIBE and account-management - http://lists.puredata.info/listinfo/pd-list
