Harware is Dell Inspiron 8200, about 2.5 years old. 2GB RAM. Fedora
Core 2 OS. I'm getting some inconsistent performance running Flightgear
flight simulator, and am wondering if the 28MB NVIDIA GeForce2 card
that came with my system is causing some problems with memory access.
Here's what happens: In the past week, with a few windows open on my
KDE desktop, the planes engine would sound like it sputters, and
there's a discontinuity between input of my joystich which affects the
plane (it pitch up or down). I just noticed that if I click on the red
hat on tool bar when plane is on runway, I hear the discontinuity
(memory access delay?) as menu options open up. It's as if as images
appear on my screen, there's an effect on flight simulator performance.
I know flightgear is pretty graphics intensive.
I'm using a ViewSonic 1600x1200 external LCD monitor.
Is there any way I can tell if the NVIDIA card is not robust enough to
run the simulator? I don't want to spend big $$$ on a better video
card without being sure that's the problem. The video driver was
updated recently for the latest kernal release.
