Any insight? First thx for all the replies. They helped me to narrow down the scope of the problem and I finally got the culprit. It turned out that under both Linux and Windows very low FPS were related to the 32-bit color. Once I changed it to 16-bit the improvement was dramatic. Also under Linux that trouble with resizing the FG window is gone now. Here are some other observations: -I pretty much do not see any correlation between window size and the FPS (unlike with some games) -CPU often hits 100%, but especially when I fly close to ground, it drops to even 60%, all rendering options are on -glxgears cranks around 12000 FPS (which is definitely higher than 32-bit colors) -I have got FG FPS from 60 to 90. Completely sufficient and some room for future. ..you cut your colors from 32bit to 16bit, ATI's cards are all 24bit, how are your 24bit framerates? -- ..med vennlig hilsen = with Kind Regards from Arnt... ;o) ...with a number of polar bear hunters in his ancestry...

[Flightgear-users] FlightGear gets slow under Linux when resizing window
2. I run latest version of the FG on both Win 2K and Mandrake 10.0 (with Nvidia drivers of course). However I note very strange behavior under Linux. When the FG starts in the default window (I guess it is 640x480 or so), it performs quite well but when I try to resize/make bigger/maximize the window everything starts crawling. I do not observe it under Windows where it runs smoothly even under really high resolutions. I am not sure if it is due to the Linux and Windows use that 32MB of my poor GeForce differently or what? Any insight? Unfortunately problem somehow returned. I even compiled FG out of CVS (plus all fresh libs it depends on) in order to test it and it still persists. I attach links to three jpg (generated on the previous .92 version) 1.jpg -before - 64 FPS 2.jpg -during resizing - it takes 5-15 seconds 3.jpg -after - 1 FPS Have you any idea what is going on? http://home.comcast.net/~leszczynscy/1.jpg http://home.comcast.net/~leszczynscy/2.jpg http://home.comcast.net/~leszczynscy/3.jpg Thx, A. ___ Flightgear-users mailing list Flightgear-users@flightgear.org http://mail.flightgear.org/mailman/listinfo/flightgear-users 2f585eeea02e2c79d7b1d8c4963bae2d
