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?
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.
Thx, A.
