Hi,
this occured to me the first time when I changed over to Linux, never
had that on WinXP.
After some research I found that I have to change the video sync in my
NVIDIA X Server Settings. This reduces the frame rates (ie 115 to 85)
but the stuttering is corrected and FlightGear runs very smooth, both on
PLIB and OSG.
NVIDIA X Server Settings GUI (KDE) - sorry, I am a KDE fan, can only
report this
X Server XVideo Setting
check
(Video Texture Adaptor:) Sync To VBlank
(Video Blitter Adaptor:) Sync to VBlank
OpenGL Settings, Performance
check
Sync to VBlank
(Allow Flipping is already checked, I did not notice any
difference un/checked)
I don't know whether you have a NVIDIA graphic card or if this also
works for you, but with my system it is *essential* to get a smooth
working FG system:
OpenSuse 10.1 x86_64
NVidia 6600 GT 256 MB, PCI Express 16x
VBIOS Version 05.43.02.80.00
NVIDIA Driver Version 1.0-8762
