Which Flightgear version will run on my "older" computer

[everell]

I have an older computer....would like to put Flightgear on. It has a Pentium 4 3 gig cpu, Intel 915 chipset, and NVidia video card with 512 meg of memory. I am using the Ubuntu 10.04 operating system. I realize it probably won't run the latest Flightgear release, but at least it is not a TRS-80. Your recommendations please.

Is it a Pentium 4 single core with Hyperthreading?
What Nvidia card?
How much system ram?

The old Ubuntu might actually be a bigger limitation than the hardware - why that old?

Flightgears rendering got better (more efficient) around 3.6 and has actually been getting better with each release since then - if you are having framerate issues you can always turn off rendering features like vegetation & turn certain shaders down

If you still have issues then use World Scenery 1.0 rather than the current scenery

My pc is not up to running the latest version so runs Flightgear 2.6.0.1 the exe. is only 526Mb but it still renders nice fluffy cumulus cloads as you can see in the videos.

I'd just try the newest release; it doesn't cost you a thing, other than maybe half an hour of your time.
