(none) Also I locked the X down to 16 bpp Also glxgears gives me 1400 fps in current setting small window full screen it gives me 300, this is with 16 bit depth with 32bit it gave me 1240 fps in its default window and 170 in full screen I also play gl-117 (openGL action flight simulator) gives me about ~50fps running in view realism(range 1-5) 2 and quality(range 30-150) 100. and this is in fullscreen 1280x854 24 bpp > > ..try: " fgfs --geometry=1920x1440 --httpd=5555 > --jpg-httpd=5556 \ > --prop:/controls/gear/brake-parking=1 & " to keep > it parked while > you check the sim control web server and the screen shot > server > from another box on your lan. > I tried this and here is what I found : any http request made from the lan to either of the 2 servers takes 10-15 minutes for a response from the fgfs ..... althought the load on the ppc-linux running fgfs is about 1.4 and all things except fgfs are very responsive. > ..an alias to try: alias aiglxbenchmark='w ; cat > /proc/version \ > ;cat /proc/pci |grep VGA ||lspci |grep VGA |colrm 1 4 ;cat > \ > /proc/cpuinfo |egrep "model name|MHz|bogomips" > ;xdpyinfo |egrep \ > "version:|dimensions|depth of" ;glxinfo |egrep > -A2 "direct \ > rendering|OpenGL vendor" ;cat /var/log/Xorg.0.log > |grep \ > architecture ;cat /var/log/Xorg.0.log |grep flip ;glxgears > \ > -info & sleep 51 ;killall glxgears ;w ;glxgears > -fullscreen & \ > sleep 51 ;killall glxgears ;w ', for fullscreen > glxgears, you > wanna see at least 85fps. > > > -- > ..med vennlig hilsen = with Kind Regards from Arnt... ;o) > ...with a number of polar bear hunters in his ancestry... > Scenarios always come in sets of three: > best case, worst case, and just in case. > > ------------------------------------------------------------------------- > This SF.Net email is sponsored by the Moblin Your Move > Developer's challenge > Build the coolest Linux based applications with Moblin SDK > & win great prizes > Grand prize is a trip for two to an Open Source event > anywhere in the world > http://moblin-contest.org/redirect.php?banner_id=100&url=/ > _______________________________________________ > Flightgear-devel mailing list > Flightgear-devel@lists.sourceforge.net > https://lists.sourceforge.net/lists/listinfo/flightgear-devel ------------------------------------------------------------------------- This SF.Net email is sponsored by the Moblin Your Move Developer's challenge Build the coolest Linux based applications with Moblin SDK & win great prizes Grand prize is a trip for two to an Open Source event anywhere in the world http://moblin-contest.org/redirect.php?banner_id=100&url=/ _______________________________________________ Flightgear-devel mailing list Flightgear-devel@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/flightgear-devel
